Python for Absolute Beginners Transcripts
Chapter: Using external Python packages
0:00 Our game is okay, but boy could it use some color
0:03 or some UI or something, right?
0:06 It all just blends together.
0:07 It would be much, much nicer if we could quickly indicate
0:11 who's playing what, whether or not you've won, and so on.
0:14 So what we can do, is we can use an external library
0:17 that will make it very easy for us to output color
0:20 instead of regular lain text.
0:22 You can do it without these libraries,
0:23 but it's complicated,
0:24 it's different across different operating systems.
0:27 With these cool external libraries, you just basically say
0:29 print, but make it blue, or print, but make it yellow,
0:32 and then out it comes.
0:33 So this is actually going to be a big improvement to our app,
0:36 and we're going to get a library called Colorama
0:38 that let's us do this.
0:40 But, we could go a little farther.
0:41 We could come in here and we could say,
0:43 in addition to color, it's one thing to have that great
0:46 long list of one, two, three, four, five,
0:48 but what about a little dropdown in our terminal here?
0:51 That'd be really cool, right?
0:53 And it can autocomplete, so if we typed S,
0:56 it'll pull up scissors and sponge in our final example.
0:59 Even if we typed, I don't know, R,
1:01 it would pull up rock, and scissors,
1:02 and I guess paper, as well.
1:04 But, you know, if you type enough that it's going to narrow
1:06 it down, then it'll pull those up.
1:07 Like if you hit C, it would be rock and scissors.
1:10 So, we're going to be able to add that little UI
1:11 using a different library and combine these two,
1:15 and you'll see that it's easy to do.
1:17 We basically say their name, we ask Python
1:19 to go get them for us, and then we can just start working
1:21 with these extra libraries.
1:23 It's going to be really fun.
