00:00 So, we've seen that we can run our app,
00:02 and let's actually run it over here.
00:04 We could go to somebody and say,
00:06 all right here's what you need to do
00:07 to run our little program.
00:09 You have to create the virtual environment
00:10 and then you have to activate the virtual environment.
00:13 They have to pip install the actual requirements.
00:19 Once that's all set up, you can Python your program,
00:22 and whew, it runs, finally.
00:24 Okay, so that's not really the way you want to hand out
00:27 a general application, is it?
00:29 You want to say, here, double click this.
00:31 It looks just like your Firefox, or your Word,
00:34 or whatever application people are used to working with.
00:36 So, we're going to use a program,
00:38 or a utility, called PyInstaller.
00:41 So, over here, the first thing have to do
00:44 to use PyInstaller, is install it.
00:50 Now, PyInstaller works on all of the platforms,
00:53 so that's really nice, and the easiest way to run it
00:56 is to create a file called build.spec.
01:00 And if you go to the PyInstaller page,
01:02 it'll say, here's an example one.
01:04 So we're going to do, basically, grab this.
01:10 I'm going to grab some text, basically, that I got from there,
01:12 other than I put in the name, so you can see like
01:15 right here, Movie Search App is the name.
01:19 But it does things like, don't you have the console,
01:21 make it windowed, things like that.
01:23 And the other thing it needs is the Python path,
01:26 so I'm going to say, which Python,
01:28 with my virtual environment activated.
01:30 So in that case, we're going to use
01:31 this great long one there, okay.
01:37 That should pretty much be it.
01:39 Go through, set the name of your application
01:41 and things like this.
01:42 So once this is here, we can come over here, and we can,
01:46 in our terminal, either one will do,
01:48 we just say PyInstaller, let's do it over
01:50 in this bigger one, 'cause you'll see
01:52 all the stuff that comes out.
01:53 So again, the virtual environment is there,
01:56 this build spec is here,
01:57 so we'll say PyInstaller ...
02:01 So PyInstaller build.spec.
02:07 It's done. It's completed successfully.
02:09 How awesome it that?
02:10 That took a moment, but let's go see
02:11 what we have in here now.
02:13 Just minimize everything.
02:14 And now, in our final search app, we have a build folder,
02:17 which is kind of a temporary working directory
02:18 and it will be quicker if you rerun the PyInstaller
02:21 based for that stuff is there.
02:23 But this is what we care about. Look at this.
02:25 This one .app file, put it over here.
02:29 Now, what happens if I double click it?
02:32 Wait for a second.
02:33 And there's our UI. Let's go search for something.
02:36 I'm going to search for "action,"
02:39 and this will be a general keyword.
02:41 Boom, there are eight movies, the action in it.
02:43 So, Last Action Hero, Looney Tunes: Back in Action,
02:46 Civil Action, things like that.
02:48 How cool is that?
02:49 Now, you may notice this
02:50 little thing back here, this terminal.
02:53 That is actually what I would call not cool,
02:55 so I'm going to close that.
02:56 Now, if I go over to my Windows virtual machine,
02:59 and I run the exact same process.
03:01 I pip install, I run the requirements,
03:03 and then I pip install, PyInstaller,
03:05 and I run PyInstaller build.spec, I will get a single .exe,
03:10 and that single exe will run just like we saw.
03:14 But it has no command prompt.
03:16 It literally runs as just a Windows application.
03:18 If I do the same thing on the Linux
03:19 after I get the funky stuff to install with Aptitude,
03:22 then I run the PyInstaller,
03:24 I get this to show the Gooey, no terminal.
03:27 For some reason, I think it's a minor bug
03:28 with PyInstaller that this is shown,
03:32 even when I'm in the command thing.
03:34 We told it not to, but still,
03:36 the benefit of having a thing I can double click right here,
03:40 and that Gooey comes up in Python, that is really sublime.
03:44 And the fact that this is all bundled up.
03:45 I literally just compressed this .app and I send it around.
03:49 There's no dependencies. Even better.
03:51 So, I really hope you like this ability create
03:54 a Gooey and then package it up for reuse,
03:56 because I think that really broadens the reach
03:59 of what you can do with Python.
04:01 Now, these are not super, super general applications
04:03 that you've seen.
04:04 There are some nice examples.
04:06 If we go to the Gooey page and we scroll down here,
04:09 scroll, scrolling, you see some nice examples,
04:10 even at the bottom, I think there's some here.
04:13 Yeah, you can see tabbed groups, custom groups,
04:16 sidebar navigation, all kinds of stuff going on here.
04:19 But what I want to show you is, if you go to the examples,
04:23 there's actually a different repository
04:25 with a bunch of different examples.
04:27 Success screen, error screen, flat versus column layout,
04:31 all that kind of stuff. So you can go over here and play around with those,
04:33 just even like a dynamically generated one.
04:35 So, you can do a lot, but you can't build
04:38 entirely general applications.
04:40 This is a quick way to turn command line apps
04:43 into rich Gooey apps, and I think it does it really well.
