Installing Python modules with the pip tool is surprisingly hard to describe to beginners learning to code. There are several potential issues: multiple Python installations, virtual environments, PATH environment variable settings. You have to introduce command-line terminals and file system navigation, and the differences between Windows and Mac/Linux. However, there is a line of code you can run from the interactive shell to handle all this for you.
Regular expressions (aka regexes) are a mini-language to specify a pattern of text to look for. However, regex syntax is composed of various punctuation marks that can be hard to remember. Humre is a Python module that gives a more human-readable syntax that works better with code editing tools. You can install Humre just like any other Python module with
pip install humre and the full documentation is available in the git repo's README file.
Let's look at a simple example of a recursive function to see what it needs at minimum.
Here's the boilerplate that you can copy and paste when creating a new web page with Bootstrap 5.
Python 3.11 will include a TOML parsing module called
tomllib. Let's learn what TOML files are (they're similar to JSON), how they're useful for configuration files, and how you can write Python code to read them.
You don't need to buy a new computer to learn programming. It's a common misconception that you need a powerful computer to program. This guide will give you some hints to guide you in the right direction.
Mark H. Liu’s “Make Python Talk” is a solid book for anyone who wants to leverage the power of the Python programming language to add speech capabilities to their programs. The chapters cover third-party libraries for speech recognition and text-to-speech in an engaging way.
Serious Python by Julien Danjou is an excellent book for those who have gone through the "hello world" tutorials or those coming to Python from other programming languages, and want a book that teaches you not just how to write code, but how to write code the pythonic way.
Writing for an intermediate audience is hard, but Ken Youens-Clark has nailed it with Tiny Python Projects. This is a great book for those who have dabbled with a few beginner Python tutorials but still feel like they don't "get" programming. The projects in this book are short and simple; perfect for beginners who want to get experience with actual programs instead of just code snippets.
This blog post examines different ways that Python lists and dictionaries can be used to represent a 2D data structure. I also write some test programs to measure the performance of each data structure.
How to Test Multiple Variables Against a Single Value and a Single Variable Against Multiple Values in Python
Python has a more concise syntax that uses the
in operator and the multiple values packaged in a tuple. To check if one of multiple variables is one of many values, you can use a list comprehension and the
I was one of those kids in the 90s who taught themselves how to code by making video games in the BASIC programming language. Later, I majored in computer science, moved to Silicon Valley, became a software engineer, started writing programming books including Automate the Boring Stuff with Python, and then quit my job to write full-time. I now wake up whenever I want and work from home or nearby cafes. I'm financially secure while being my own boss.
This is a completely true story.*
Here are 22 actual, runnable Python code for several recursive functions, written in a style to be understandable by beginners and produce debuggable output.
