Speaker 1: Welcome to the deep dive. You know how this works. Yeah,
Speaker 1: you send us your stuff, your sources, and we well,
Speaker 1: we dive deep to pull out the really important bits.
Speaker 2: Exactly. The goal is to get you up to speed
Speaker 2: quickly without you having to weigh through everything yourself.
Speaker 1: So today, based on what you sent over, we're looking
Speaker 1: at these excerpts from twisted Python projects. Specifically, the first
Speaker 1: few chapters all about building gui's graphical user interfaces.
Speaker 2: That's right, using Python and a library called guy zero.
Speaker 1: Looks like you're aiming to figure out how to make
Speaker 1: Python apps you can actually you click on and interact with.
Speaker 2: And these early chapters seem like a really practical starting point.
Speaker 2: We'll look at how guy zero is supposed to make
Speaker 2: things easier, starting with a basic Hello Gui.
Speaker 1: Right. Then there's a joke Machine project and something called
Speaker 1: a fart box soundboard.
Speaker 2: Okay, yes that one's quite something, but they all teach
Speaker 2: useful concepts.
Speaker 1: I saw the subtitle twelve wacky, useful, tricky, cool fun
Speaker 1: things to do That definitely taught my eye. Yes, we're
Speaker 1: not just like learning syntax rules.
Speaker 2: No, definitely not. It's about building tangible things, which is
Speaker 2: often a much more engaging way to learn coding, right,
Speaker 2: helps the ideas stick.
Speaker 1: Okay, let's jump in chapter one. Low, gy, what are
Speaker 1: the aims here? Looks like understanding Python. GUIs getting set
Speaker 1: up and.
Speaker 2: Building that very first interactive window.
Speaker 1: Yeah, now, Python, Well it's everywhere, isn't it. The book
Speaker 1: calls it one of the fastest growing programming languages, superversal.
Speaker 2: Absolutely, websites, games, automation. Yeah, you can do a lot
Speaker 2: with it, and it's generally seen as easier to read
Speaker 2: than some other languages.
Speaker 1: Which probably helps explain his popularity. And the name I
Speaker 1: saw that mention.
Speaker 2: Oh yeah, the Monty Python connection. Gredovin Rossum. The creator
Speaker 2: was apparently a fan.
Speaker 1: He just wanted something short and memorable. It's kind of
Speaker 1: funny for such a powerful tool.
Speaker 2: It is shows you don't always need a super serious name.
Speaker 2: And the book highlights Python's simplicity early on, right with.
Speaker 1: The Hillo World example. Just print Hello World simple.
Speaker 2: Compared to some other languages. The need Moore set up
Speaker 2: lines just for that.
Speaker 1: Yeah.
Speaker 2: The idea is fewer lines can mean fewer places for errors.
Speaker 1: Okay, so that's Python, but we're building Jui's Guy's Hey.
Speaker 2: Yeah, the book uses that Cadbury's cream eg analogy.
Speaker 1: It does a visual way to interact. Yeah, and so
Speaker 1: just typing commands exactly.
Speaker 2: Think about your smartphone ATMs, anything with buttons and icons
Speaker 2: on a screen, that's a GUI. It's usually much more
Speaker 2: intuitive for most people.
Speaker 1: Makes sense. And the tool for this in the book is.
Speaker 2: GOO zero right, created by Laura Sak and Martin O'Hanlon.
Speaker 2: The book says it's specifically designed as a simpler way
Speaker 2: to make UIs in Python three, especially for learners.
Speaker 1: So it's a library like a collection of pre written code.
Speaker 2: Precisely. It gives you building blocks, buttons, textboxes, so you
Speaker 2: don't have to code them from scratch every single time.
Speaker 2: Saves a lot of effort.
Speaker 1: And the book mentions an easy install option too, just
Speaker 1: downloading files.
Speaker 2: Yeah, that can be useful if you're on a computer
Speaker 2: where you maybe can install software normally, But the standard way.
Speaker 1: Is using the command prompt right with PIP three exactly.
Speaker 2: PIP three installed zero. KIP is Python's package installer. Think
Speaker 2: of it like an app store for Python code libraries.
Speaker 2: It fetches GU zero and sets it up for you.
Speaker 1: Okay, and once it's installed, GO zero has elements and widgets.
Speaker 2: Yeah, that's how the book categorizes things. Widgets are the
Speaker 2: visible things you interact with. Buttons, text, inputs, labels. Elements
Speaker 2: are more about structure and behavior like layout or handling events.
Speaker 1: Gotcha. Now to write the code, you need an id.
Speaker 2: An integrated development environment. Yeah. It's basically a specialized text
Speaker 2: editor for code.
Speaker 1: And Python comes a one called IDL E pronounced idle.
Speaker 2: That's the one it's built in, so it's convenient to
Speaker 2: get started with. The book focuses on using IDL E,
Speaker 2: and it.
Speaker 1: Stresses organizing your code into sections, imports, variables, functions, app.
Speaker 2: Which is really good practice. It makes your code much
Speaker 2: easier to read, understand, and importantly debug later on.
Speaker 1: Okay, let's walk through that first project. Hello Gui. It's
Speaker 1: like Hello World, but interact right.
Speaker 2: Instead of just printing text, you get a window. You
Speaker 2: type your name in a box, click a button, and a.
Speaker 1: Pop up says hello plus your name exactly.
Speaker 2: It introduces input, the user typing their name and output
Speaker 2: the pop up message. Very fundamental concepts.
Speaker 1: First step, the book emphasizes save the file like Hello Gui,
Speaker 1: dot poy.
Speaker 2: Always save early, save often good advice.
Speaker 1: Then the import section we need app for the main window,
Speaker 1: info for the pop up message. Yet that's specific type
Speaker 1: of pop up, push button for the button, textbox for typing,
Speaker 1: and text for labels.
Speaker 2: And you import them from Guizero. You're telling Python, I
Speaker 2: need these specific tools from the Gui zero toolkit.
Speaker 1: The book also explains comments lines starting with hashtag ignored
Speaker 1: by Python but helpful for humans reading the.
Speaker 2: Code, essential for documentation and explaining complex parts.
Speaker 1: Then variables. The book uses that labeled jars analogy for
Speaker 1: storing data in memory.
Speaker 2: It's a good analogy. While this first project isn't heavy
Speaker 2: on variables, the concept is crucial for almost any program,
Speaker 2: so introducing it early makes sense.
Speaker 1: Next, functions many programs for specific tasks.
Speaker 2: Right, you define them once using def like deaf hello,
Speaker 2: and then you can call that function whenever you need it.
Speaker 1: The book uses a game over sequence as an example.
Speaker 1: Right at once, call it multiple times saves repeating code.
Speaker 2: Exactly in this project. The Hello function contains the code
Speaker 2: to create that pop up message.
Speaker 1: He uses info and joins Hello with whatever's in the textbox.
Speaker 1: String concatenation yep.
Speaker 2: Just stick in pieces of text together, and.
Speaker 1: The book mentions syntax here. The grammar of code using
Speaker 1: that Thor's hammer example. Yeah, spelling and structure matter.
Speaker 2: They absolutely do. A misplaced comma or a typo can
Speaker 2: stop the whole thing from working.
Speaker 1: Okay. Finally, the hashtag app section building the actual GUI.
Speaker 2: This is where you put the pieces together.
Speaker 1: App app Hello World creates the window and.
Speaker 2: Sets the title app is the main container.
Speaker 1: Then added text widget for instructions and to your name
Speaker 1: the static label. Then the textbox widget for the user
Speaker 1: to type in.
Speaker 2: You can set the width right control the size.
Speaker 1: You push button. This is key command Hello links the
Speaker 1: button click to our hello function.
Speaker 2: That's the connection event. Button click triggers the function show.
Speaker 1: Pop up, and you set the buttons label like click
Speaker 1: me yep. And the most important line maybe app dot.
Speaker 2: Display absolutely critical. Without that, you define the GUI, but
Speaker 2: it never actually shows up on the screen.
Speaker 1: Then you run it usually F five and IDL E.
Speaker 1: The book also lists common.
Speaker 2: Errors to check installation issues, typos, case sensitivity, the usual
Speaker 2: suspects when you're starting out.
Speaker 1: And I like that. Three other things to try A
Speaker 1: bit change background color with big, resize the textbox, use
Speaker 1: a worn pop up instead of info.
Speaker 2: Encourages experimentation right away, reinforces learning by doing.
Speaker 1: Yeah, and the recap of terms zero, widgets, functions, useful summary.
Speaker 2: Definitely helps solidify those core ideas.
Speaker 1: Okay, moving on chapter two, Are you funnier than a hyena?
Speaker 1: The choke machine? Hey?
Speaker 2: Yes, a gooi with a button that shows a random joke.
Speaker 2: Simple idea but introduces new things.
Speaker 1: The book mentions the benefits of laughter. First, nice touch,
Speaker 1: that's the mood.
Speaker 2: And this project teaches about using Python's random module and
Speaker 2: working with lists.
Speaker 1: So imports. First, we need app text push button from
Speaker 1: guy zero.
Speaker 2: Against standard Gooi elements.
Speaker 1: But also import random that's built into Python itself.
Speaker 2: Right, Yes, random is part of Python's standard library. Very
Speaker 2: useful module.
Speaker 1: Then we need jokes. The book explains lists storing multiple
Speaker 1: items in one variable like a shopping list.
Speaker 2: Good analogy. Here we create list of jokes and put
Speaker 2: joke strings inside parentheses separated by commas.
Speaker 1: Right, and use underscores in the variable name list of jokes, not.
Speaker 2: Spaces common Python style makes it readable.
Speaker 1: The book suggests using print to check the list first,
Speaker 1: then commenting it out smart debugging.
Speaker 2: Yeah, print debugging is simple but effective. Check the data
Speaker 2: looks right before you use it.
Speaker 1: Okay. The core logic the select joke function. How does
Speaker 1: it pick a random one?
Speaker 2: It uses random dot rand range. This function needs a
Speaker 2: range of numbers to pick from, and that.
Speaker 1: Range relates to the position of jokes in the list.
Speaker 1: Python lists start at index zero.
Speaker 2: Right exactly, first joke is at zero, second, one, and
Speaker 2: so on. So if you have four jokes, the indices
Speaker 2: are zero, one, two, three.
Speaker 1: But we don't want to hardcode the upper number of
Speaker 1: the range in case we add more chokes.
Speaker 2: Right, That's where lin list of jokes comes in. Lynn
Speaker 2: gives you the number of items in the list. Ah,
Speaker 2: So random dot rand range Lin list of jokes. We'll
Speaker 2: always pick a valid random index from zero up up
Speaker 2: to but not including the link precisely.
Speaker 1: It adapts automatically. If you change the number of jokes
Speaker 1: very flexible.
Speaker 2: Then you use that random index to get the actual
Speaker 2: joke string from the list.
Speaker 1: Yep like list of jokes random.
Speaker 2: Index, and how do we display it? The book mentions
Speaker 2: a text widget and its dot value attribute.
Speaker 1: That's right. You create a text widget, maybe initially empty,
Speaker 1: and then inside the function you set it's that value
Speaker 1: to the chosen joke string. That updates what's shown on
Speaker 1: the screen.
Speaker 2: Okay, building the GUI itself, set the app title joke
Speaker 2: machine maybe set with in height.
Speaker 1: Standard set up with app. You can also set the
Speaker 1: background color using app dot BG, add a.
Speaker 2: Title text maybe using a specific font like impact.
Speaker 1: Yeah text widget. Again, customizing text size and font adds
Speaker 1: a bit of personality.
Speaker 2: And the button push button link to select joke using
Speaker 2: command select joke button text tell me a joke.
Speaker 1: Just like the hellogi button, but triggering the joke function
Speaker 1: this time.
Speaker 2: And we need that empty text widget where the joke
Speaker 2: will appear yep, a placeholder that gets updated by.
Speaker 1: The function, and app dot display to show it all.
Speaker 2: Can't forget that.
Speaker 1: The book also shows how to make it automatic jokemachine
Speaker 1: auto dot pi yeah.
Speaker 2: Using the repeat method, you can tell a widget like
Speaker 2: the joke display text to repeatedly call a function after
Speaker 2: a certain time interval.
Speaker 1: And that interval is in milliseconds.
Speaker 2: Correct, so you need to convert seconds or minutes to
Speaker 2: milliseconds seconds times one thousand.
Speaker 1: Cool, so you could have a joke pop up every
Speaker 1: minute or.
Speaker 2: Something exactly a bit of scheduled fun.
Speaker 1: Again. Things to try, shange font, colors, background, add a
Speaker 1: funny picture with the picture widget.
Speaker 2: More encouragement to tinker and learn by modifying and.
Speaker 1: A recap, variable list, iteration, building blocks.
Speaker 2: Slowly adding more tools to your programming toolbox.
Speaker 1: I Prepare Yourself. Chapter three fart Box a disgusting soundboard.
Speaker 2: Yes, memorable if nothing else. The goal is a GUI
Speaker 2: with buttons that play.
Speaker 1: Sounds, specifically fart sounds. Okay, yeah, But the skills learn
Speaker 1: seem useful layouts buttons triggering sounds, audio playback functions, file
Speaker 1: handling images exactly.
Speaker 2: Beneath the surface humor, there are solid programming concepts here.
Speaker 2: Layouts are particularly important for more complex interfaces.
Speaker 1: So first you need sound files dot waveformat and an
Speaker 1: image PNG or dot gift.
Speaker 2: Right, and the book stresses organization. Create a subfolder maybe
Speaker 2: called farts for these media.
Speaker 1: Files, and save the pythons grit, fartmachine, dot PUI in
Speaker 1: the main folder outside the farts folder.
Speaker 2: Good structure keeps codes separate from assets.
Speaker 1: Imports app box, picture, push button text from new zero
Speaker 1: familiar stuff yep, but also import wind sound. That's for
Speaker 1: playing sounds on Windows.
Speaker 2: Correct, it's a Windows specific module. The book notes simple
Speaker 2: idio as an alternative for Mac and Linux users.
Speaker 1: Important distinction cross platform compatibility.
Speaker 2: Definitely something to be aware of when dealing with things
Speaker 2: like audio or system features.
Speaker 1: Now the functions one for each sound dot fart one
Speaker 1: to fart six makes sense.
Speaker 2: Each function's job is simple play one specific sound file.
Speaker 1: Using winsound dot playsound. It needs the path to the
Speaker 1: sound file like fartsfart one, dot wave and that windsound
Speaker 1: dot s and s y.
Speaker 2: And C flag right snds CIC means a synchronous play
Speaker 2: the sound, but don't make the program wait for it
Speaker 2: to finish. The guy stays responsive, crucial for.
Speaker 1: A soundboard where you might click buttons rapidly exactly. There's
Speaker 1: also an exit function plays a burp dot wave, apparent
Speaker 1: it a final flourish, and then uses app dot destroyed
Speaker 1: to close the window.
Speaker 2: App dot destroy is the command to properly shut down
Speaker 2: the good zero application.
Speaker 1: Okay, GUI build time app fart box set with height
Speaker 1: background saddle brown.
Speaker 2: Oh my thematic consistency perhaps?
Speaker 1: Uh huh? Add a title text, add a picture widget
Speaker 1: for the image. So we're adding visuals.
Speaker 2: Too, Yes, showing how to integrate images alongside other widgets.
Speaker 1: Now layout this uses the box object like an invisible container.
Speaker 2: That's a great way to think of it. It helps
Speaker 2: group and arrange other widgets.
Speaker 1: And here it uses layout grid so we can place
Speaker 1: buttons in rows.
Speaker 2: And columns exactly like coordinates on a map or sells
Speaker 2: in a spreadsheet. The book uses grid x y, where
Speaker 2: x is the column and why is the row. Remember
Speaker 2: zero based again, so grid.
Speaker 1: Zero zero is the top left position in the box.
Speaker 1: Then we create the push button widgets inside this box.
Speaker 2: Yes, specifying the box as their parent container.
Speaker 1: Each button gets linked to its fart function via command
Speaker 1: gets button text fart one and its position. Using grid exit.
Speaker 2: You carefully place each button in the desired grid sell
Speaker 2: same for.
Speaker 1: The exit button linked to exit text exit placed in
Speaker 1: the grid and maybe colored red using dot pg.
Speaker 2: Visual q that it does something different like closing the app.
Speaker 1: And finally dot app dot display.
Speaker 2: Bring the box to life.
Speaker 1: The book includes troubleshooting again audio settings, file formats, folder structure,
Speaker 1: function names, matching commands, typos, all the.
Speaker 2: Common pitfalls, especially when dealing with external files and specific
Speaker 2: function names and things.
Speaker 1: To try change individual button colors, add more buttons and sounds.
Speaker 2: Which means creating more functions, more push buttons, figuring out
Speaker 2: new grid coordinates, maybe resizing the box good practice, and
Speaker 2: scaling up.
Speaker 1: The chapter ends with statements of fact summarizing GUI zero
Speaker 1: concepts like box, grid picture.
Speaker 2: Nice little recap reinforces the terminology from this chapter and
Speaker 2: it gives.
Speaker 1: The install command and basic usage for simple audio two
Speaker 1: Windows users.
Speaker 2: Good on them for including that explicitly makes the project
Speaker 2: more accessible.
Speaker 1: So wow, Okay, that covers the first three chapters. We
Speaker 1: looked at. Quite a journey from a simple pop up
Speaker 1: to a multi button soundboard.
Speaker 2: It really is, and based on these excerpts, you should
Speaker 2: have a well a foundational grasp of making gewiyes with
Speaker 2: Python and guzero.
Speaker 1: From Hello World with a button to random jokes to
Speaker 1: well the fart box.
Speaker 2: And even if the examples are a bit quirky, the
Speaker 2: underlying principles widgets, events, functions, layouts using libraries are really
Speaker 2: core programming ideas.
Speaker 1: Yeah, you've gotten from basic syntax to building things that
Speaker 1: actually do stuff on screen, respond to clicks, play sounds.
Speaker 2: It's a tangible way to see your code come to life,
Speaker 2: which can be really motivating.
Speaker 1: Definitely, and I think taking that advice to try the
Speaker 1: extra challenges, tweak the code, add your own jokes or sounds,
Speaker 1: that's where you really make it your own.
Speaker 2: Absolutely that hands on experimentation is crucial. Don't just copy
Speaker 2: the code, play with it, break it, fix it. That's
Speaker 2: how you learn.
Speaker 1: So here's a final thought to maybe Neutilon. Now that
Speaker 1: you've seen how well relatively easy Gay zero makes building
Speaker 1: these interfaces, what else could you build?
Speaker 2: Yeah? What everyday little tools or maybe bigger ideas or
Speaker 2: even just silly concepts could you try and create with
Speaker 2: a bit of Python geocode?
Speaker 1: Think about it? What would you like to make interactive?
Speaker 2: It's a great question. And hey, if you do build
Speaker 2: something cool or have more questions as you explore, we'd
Speaker 2: be interested to hear about it. Might even inspire another
Speaker 2: deep dive.
