It's time to write interactive code
0:02
and this is where writing programs
0:03
and doing software really fun.
0:06
So far, what we've done is we've just told the program
0:09
Do Step One, and then Step Two, and then Step Three.
0:12
Maybe we got some input from the user
0:14
but there was no decision or alternate paths made around it.
0:18
So, we're going to write code and make the code decide.
0:22
Think of the Talk Python website.
0:24
If you go there and you're not logged in
0:25
it'll do one thing, if you are logged in, it'll do another.
0:27
For example, if you try to view a course
0:29
and you're not logged in, it'll tell you to log in
0:31
or it'll take you to the course to just browse it
0:34
and you can learn more about it and sign up there.
0:36
Once you do log in, it needs to know
0:38
does this course belong to you, are you registered for it
0:40
or is this some other course?
0:41
And it's going to decide
0:42
if you're registered, let's show them the lessons
0:44
and let them get started on the videos.
0:46
But if they're not, well
0:47
send them over to learn more about it so they can sign up
0:50
things like that. So this is where programs get real
0:53
they get fun, they get interesting
0:54
and they can do legitimately cool things
0:57
and that's what we're going to do in this chapter.
