0:00 Hello again, it's Michael.
0:02 And we're getting really near the end
0:04 of your 100 day journey.
0:06 And I think this topic is going to be a really nice one
0:08 to round out some of the work that you've already done.
0:11 We're going to talk about building GUI applications.
0:15 That's right.
0:16 Windows applications, not terminal applications.
0:20 You're going to work cross-platform just like Python,
0:22 in fact, we're going to take it a step farther,
0:24 we're even going to bundle these up so nobody will even know
0:27 you wrote them in Python.
0:29 Right, you give them an .exe, or .app, or linux binary,
0:32 and they can just run it.
0:33 It's going to be amazing.
0:35 Here is the simple application that we're going to build.
0:38 Now, we're going to start pretty simple.
0:41 We're not going to build super complicated applications,
0:45 but we're going to use a framework that basically takes
0:48 CLI, command line argument apps, and converts those
0:51 into what we would have in some sort of GUI here.
0:55 So, what might have been a command line argument,
0:58 the search term, or the mode, are now UI elements.
1:02 One you can see is free form text, one is a dropdown.
1:05 Really, really nice framework.
1:08 The framework we are going to use to build this
1:09 is something called Gooey: G-O-O-E-Y.
1:13 You know, it's a play on the spelling phonetics
1:15 of GUIs, I'm sure.
1:17 But it turns almost any Python command-line program
1:21 into a full GUI application in just,
1:23 maybe not one line of code, but just a couple lines of code.
1:27 Really, really simple and easy.
1:29 So, the bang for the buck on this one is amazing.
1:31 It's really nice to have a GUI application
1:35 and yet it's really, actually not much work,
1:37 if you're willing to accept a simple UI.
1:39 So, Gooey, we're going to do that.
1:42 We talked about packaging Python applications.
1:45 It's one thing to have a script that shows a window,
1:47 it's an entire another thing
1:49 to give a simple, single application
1:51 to a non-technical person who may or may not
1:54 have Python installed, who may or may not have
1:57 the right version or any of the dependencies installed.
1:59 Just give them one thing that they can run.
2:01 Like on Mac, it'd be great if they could just have
2:03 like a movie search app
2:04 they could double-click and it would run.
2:07 Or on Windows, a movie search app
2:08 they could double click this .exe.
2:12 There's nothing more to it.
2:13 It's literally just this .exe file,
2:15 you do that and you run it.
2:17 Or even, over here on Ubuntu.
2:19 Give them the movie search app,
2:20 they double click it, it runs.
2:22 Don't have to set up Python,
2:23 it doesn't even have to be installed on the machine.
2:25 Just like any other fully packaged application,
2:28 it's ready to go.
2:29 For this, we're going to use something called PyInstaller.
2:33 So, there's sort of two parts to this whole section.
2:36 We're going to one, build the GUI application.
2:38 Two, an additional step to add this sort of
2:42 packaged element in this distributable version to it.
2:46 It's really fun.
2:47 I really hope you enjoy it
2:48 and we're going to get started right now.
