In this video I'll provide you some extra resources
0:03
to read up about refactoring
0:05
and how to make your code more Pythonic.
0:08
Read about the topic of refactoring,
0:10
we have a whole dedicated post
0:12
on the importance of refactoring code.
0:15
Errors should not pass silently, as we've seen.
0:19
So a lot of this we've discussed in this notebook,
0:22
but it shows you some more examples.
0:24
This is an important one, there's some Python mistakes
0:28
the beginner is likely to make.
0:30
And we listed them here
0:31
so you can know about them in advance.
0:34
There's string formatting we discussed
0:38
and Julian had a very nice article here.
0:41
From going from the terribly un-Pythonic method
0:44
to the nicer way.
0:45
And I think he come to the same conculsion
0:47
that you really want to use f-strings if you can,
0:50
if you're on 3.6.
0:52
There's an awesome talk about beautiful idiomatic Python,
0:55
by Raymond Hettinger.
0:57
I learned a lot from this talk,
0:59
there's a lot of good tips and tricks in it.
1:01
And we've made a summary in this blog post.
1:04
And when we talk about modules, and splitting your code,
1:08
it becomes important to know about packaging your code.
1:11
So here we have a post about how to do that
1:14
on a practical project, like her Karma Bot.
1:17
And it's not that hard, I mean basically
1:19
you have to make an init.py file
1:22
and know how to import your stuff.
1:24
That's important.
1:25
The imports mights be confusing,
1:27
but with this article it should become clearer.
1:30
So when we're talking about splitting code
1:32
and making it maintainable, know how to work with modules
1:35
and packaging is important.
1:37
And generic code quality resources, I have two.
1:41
First of all Martin Fowler's Refactoring Book,
1:44
and yes, the examples are in Java, not Python.
1:47
But it's about the general principles.
1:50
And this book really teaches you how to write better code.
1:53
It shows you very practical examples
1:56
how you can refactor bad code
1:58
into much more maintainable code.
2:00
It's a great read.
2:02
And of course, Uncle Bob's Clean Code, a classic.
2:06
And also shows you a lot of ways
2:08
to write professional quality code.
