Pythonic Style of Programming: Tips and Tricks

When you run code in Python, there’s a lot happening under the hood. This module sheds light on some of the lesser-known parts of Python.

As you progress through it, you’ll learn some tools and tricks that every Python programmer should know to avoid common mistakes. You can think of this module as a “Python hacks” handbook.
