How Can I Modify a List of Strings Using a Function in Python?

Modifying List Elements with Functions

Suppose we're given a list containing strings, such as:

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

We aim to modify each element in the list by applying a specific function, for instance, str.upper to get:

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

Solution: Utilizing List Comprehension

One efficient approach to achieve this modification is by utilizing list comprehension:

[item.upper() for item in mylis]

In this comprehension, for each item in the original list mylis, the str.upper method is applied to convert it to uppercase. The result is a new list containing the modified elements.
