Feb 8, 2024 · The Python walrus operator is especially useful when you want to check a condition and also use the value that is checked later on in your program. Take a look at the program below, the function distance returns the distance between two numbers regardless of their sign.
In this course, you'll learn about assignment expressions and the walrus operator. The biggest change in Python 3.8 was the inclusion of the := operator, which you can use to assign variables in the middle of expressions. You'll see several examples of how to take advantage of this new feature.
