Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.
For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

Let’s take a look at an example:

Available Fixes
Change the type-hint for the parameter:
Add an additional type-check:
Add the method to the parent class:
