How Can I Apply a Function to Each Element of a Python List?

Mapping Functions to List Elements

Suppose you are given a list like:

mylis = ['this is test', 'another test']

You want to apply a function to each element in the list. For instance, you want to apply str.upper to achieve:

['THIS IS TEST', 'ANOTHER TEST']

To achieve this, you can employ list comprehensions. Here's an example:

mylis = ['this is test', 'another test']
[item.upper() for item in mylis]

The result would be:

['THIS IS TEST', 'ANOTHER TEST']
