0:01 Are you ready to start looking at some Pythonic examples and writing some code?

0:04 I sure am, we are going to start by focusing on PEP 8.

0:07 And some of the very basic structured ways

0:10 in which you are supposed to write Python code,

0:12 and then we'll quickly move beyond that

0:15 to more the patterns and techniques

0:17 that we are going to talk about for the rest of class.

0:19 So one of the first questions about this idiomatic Python code, this Pythonic code,

0:25 is "Who decides what counts as Pythonic and what doesn't?"

0:28 The way one person writes code may very well be different

0:32 than the way another person likes to write code,

0:34 and this is one of the reasons that exactly,

0:37 specifically stating what is Pythonic code and what does it look like is a challenge,

0:41 but there is a couple of areas where we might take inspiration

0:43 and pull together some sources and find some consensus.

0:47 One of them is just the community.

0:49 We can look at blogs, Stack Overflow,

0:51 things like that and see what people are saying

0:54 and what they agree or disagree upon.

0:56 So, here is a question that asked what is Pythonic code

0:59 and there is some examples given.

1:01 Another area that people take inspiration from

1:04 is something called The Zen of Python,

1:06 and if you want to look at The Zen of Python, this is by Tim Peters

1:09 you can just type import this inside of the REPL

1:11 in any version of Python and you'll get this,

1:13 and it's things like "beautiful is better than ugly,

1:16 flat is better than nested, errors should never pass silently";

1:19 again, this is not super concrete

1:22 but it does give some sort of structure about what is important and what isn't.

1:26 We also have PEP 8, Python Enhancement Proposal 8,

1:30 one of the very first official updates to the Python language

1:34 was this thing called PEP 8 which is a style guide for Python.

1:38 Mostly this talks about the actual structure of your code,

1:41 like "you should use spaces, not tabs", those types of things,

1:44 but it also has some guidance on patterns as well.

1:47 We'll look at the few of the recommendations from PEP 8

1:50 before we move on to the more design/pattern/style recommendations.
