Real Python - 🐍 New Python tutorials on Real Python

Hey there,

There’s always something going on over at Real Python as far as Python tutorials go.

Here’s what you may have missed this past week:


Quiz: What Is the Python Global Interpreter Lock (GIL)?

In this quiz, you'll test your understanding of the Python Global Interpreter Lock (GIL). The GIL behaves like a mutex that allows only one thread to hold the control of the Python interpreter. This has advantages, but can be a performance bottleneck in CPU-bound and multi-threaded code:

Python while Loops: Repeating Tasks Conditionally

In this tutorial, you'll learn about indefinite iteration using the Python while loop. You'll be able to construct basic and complex while loops, interrupt loop execution with break and continue, use the else clause with a while loop, and deal with infinite loops:

The Real Python Podcast – Episode #242: Eric Matthes: Maybe Don't Start With Unit Tests

Should you always start testing your code with unit tests? When does it make sense to look at integration or end-to-end testing as a first step instead? This week on the show, we speak with previous guest Eric Matthes about where to begin testing your code:

Looping With Python enumerate()

Once you learn about for loops in Python, you know that using an index to access items in a sequence isn't very Pythonic. So what do you do when you need that index value? In this course, you'll learn all about Python's built-in enumerate(), where it's used, and how you can emulate its behavior:
