Learn some Python tools and tricks to avoid common mistakes.

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.

Python basics are a prerequisite, but this is a beginner-level course. Each lesson is independent and after the first chapter, you can pick up from any lesson, and you’ll be able to follow along comfortably.

# File: module.py

def some_weird_name_func_():
    print("works!")

def _another_weird_name_func():
    print("works!")

from module import *
some_weird_name_func_()

<h1> Explanation </h1>

- It is often advisable not to use wildcard imports. The first obvious reason for this is that in wildcard imports, the names with a leading underscore don’t get imported. This may lead to errors during runtime.
- The other reason is that such imports can lead to namespace pollution, i.e. they can interfere with names in the existing modules or the other modules that are being imported.

- Had we used the `from ... import a, b, c` syntax, the above `NameError` wouldn't have occurred.
