Python Snippets

Learn about Python's new assignment expression syntax and walrus operator. Assignment expressions can cut down on boilerplate code and improve efficiency!

Learn how to use the collection module's namedtuples to make your Python code even more clear and readable!

Learn all about Python's divmod function, which allows us to easily perform floor division and modulo operations in one go!

You may be familiar with Python's format method, but what about the format function? Learn to use Python's formatting language without string interpolation!

In this post we cover a lesser known string method called partition. It has a lot of similarities to split, but there are some interesting differences.

In this post we dive deeper into Python's formatting syntax, learning about displaying numbers in different bases. We also make a neat colour converter too!

In this post we continue looking at formatting, this time exploring nested string interpolation, which we can use to dynamically set formatting options.

Learn how to leverage Python's detailed formatting language to control how numbers are displayed in your applications.

Learn about conditional statements in Python: a slightly obscure bit of syntax that allows for succinct conditional logic, particularly during assignments.

In this post we learn about choices and sample: two useful functions in the random module used for generating collections of random values.

In this snippet post we look at the update method for dictionaries. We can use update to change several values at once or extend dictionaries with new keys.

In this week's Python snippet post we look at the extend method for lists. Extend works a lot like append, but allows us to append many values at once.

In this post we cover various ways we can iterate over dictionaries. Learn how to use the items and values methods to write more Pythonic loops with dicts.

zip is an incredibly powerful tool, but it has its limitations. Learn about zip_longest so you can zip collections of any length without losing data!

Python's zip function is extremely powerful and can simplify your code greatly, particularly when working with multiple iterables at the same time. In this post we cover a few ways to use it!

Print is one of the first functions we encounter when learning Python, but it can do a lot more than say "Hello, world!". Learn about print's other options and master this common function!

This week we take a look at some of Python's hidden Easter eggs, including perhaps the most important module in all of Python: antigravity.

Deques are a very handy collection type from the built-in "collections" module. They extend the functionality of lists and give us a couple more useful methods. Learn about them in this post!

This week we continue our look at the itertools module, this time covering the permutations and combinations functions.

The itertools module contains a bunch of handy functions. Here we take a look at product, which can serve as a replacement for complex comprehensions.

In this Python snippet post we cover a lesser known set method: symmetric_difference.

In this snippet post we show you how to add conditional clauses to your list comprehensions. Once you know how to use it, this kind of filtering is very powerful.

Learn how to use Python's list comprehension syntax: an awesome, Pythonic tool for creating new lists from existing iterables.

In this Python snippet post we take a look at the enumerate function: a vital tool for creating Pythonic loops.

In this post we cover shorthand operators for performing set operations in Python. We'll look at the three most common ones: union, intersection, and difference.
