Introduction to Python

if/elif/else Expressions

In our last example, you might've picked up on the fact that we didn't account for when the revenue is exactly $2000. In such a scenario, we're neither at a loss nor making a profit. So, we should tweak our code to handle such nuances.

To check a subsequent condition after your initial check, use elif. The structure goes like this:

The code following the final else will run only if none of the previous conditions are met.

Recall our previous example about string length. Let's adjust it. Now, we'll label a string as 'large' if it contains more than 20 characters, 'medium' if it has more than 10 (but certainly no more than 20), and 'small' for anything less.

Note
You can stack multiple elif blocks as required. However, it's good to note that overusing elif blocks isn't the most efficient way to structure your code.
