Welcome back to the 100 Days of Python.
0:02
In the coming 3 days I will guide you
0:04
through refractoring and writing Phythonic code.
0:08
One thing is to write Python, the other thing
0:10
is to really leverage all the great stuff Python has.
0:14
The Zen of Python states there should be one
0:17
and preferably one way to do something,
0:20
and that's great because in Python there usually is one best
0:24
way to something, and the more you know these constructs
0:27
and idioms, the more readable and elegant
0:30
your code will become.
0:31
For this lesson I've prepared a Jupyter notebook
0:34
with 10 practical examples how you can improve your code.
0:38
For example use a with statement
0:40
instead of a try, accept, finally block.
0:43
Or use enumerate to not keep a manual counter
0:47
or what about refractoring a long if,
0:50
elif else statement using a dictionary.
0:53
We will touch upon list comprehensions,
0:56
generators, using explicit is better than implicit
0:59
in your exceptions, string formatting, tuple unpacking,
1:03
PEP 8, the Zen of Python, and even some common
1:06
best practices writing maintainable code.
1:09
And for day two and three I have you refractor
1:12
your code or the code of somebody else
1:14
to really put into practice what you've learned.
1:17
So there's a lot to cover, I'm really excited.
1:19
Let's dive straight in.
