#100DaysOfCode in Python Transcripts
Chapter: Days 19-21: Iteration with itertools
Lecture: Your 3 day overview

Login or purchase this course to watch this video and the rest of the course contents.
0:00 The next three days are going to be pretty jam-packed with content for you guys to consume. So, for itertools day one, what I'd like you
0:09 to do is actually just watch the videos. There are four videos to do, and they involve cycle product combinations and permutations, okay?
0:20 I'd like you to pay specific attention to cycle, I'll explain why in a second. But, pretty much, that's all you have to do for day one.
0:29 Nice and easy. Just grasp the concept and play in the shell. I cannot stress that enough. Actually do some live coding in your Python shell, okay?
0:41 Do that to really grasp the concepts of cycle product combinations and permutations. For day two, you're going to create a traffic light script.
0:53 Okay, now what this script is going to do, it's actually going to pretty much just emulate or simulate traffic lights. Red, amber, and green.
1:03 Okay, nice and simple, it uses cycle. Which is why I want you to learn itertools cycle and pay attention to that one specifically.
1:14 And you're going to create it before you watch the traffic lights video, okay. The video is there, it'll be right after combinations
1:22 and permutations, but please try not to do that until you actually give this an attempt. Okay, give this a go yourself, and then check
1:31 the video to see how you went, okay? Now for your last day, after you've finished your traffic lights, I would like you to have a play with bite 64,
1:46 bite 17, or bite 65 on the code challenges platform, okay? These are three bites that are free for you because you're in this course.
1:59 And they will actually make you use itertools in some way, shape, or form, okay. Some of them are easy, this one's intermediate here,
2:11 and this one's also intermediate, okay. So have a good play with these three bites. There's nothing much to it; you'll code within the browser
2:22 and you'll hit test to run some tests against your code. A really great way to spend your third day. Nice and easy, it's all laid out in front of you,
2:30 you just have to focus on the code. So if you want to go to bite 64, 17, and 65 using these three links, you'll get them for free, and then
2:39 you can spend your last day just plain coding. And that is pretty much your three-day wrap-up.
2:46 Go through it, if you have any questions, always reach out. But, other than that, move on to the
