Apply function to each element of a list

Question

How do I apply a function to the list of variable inputs? For e.g. the filter function returns true values but not the actual output of the function.

Answer 1

Or, alternatively, you can take a list comprehension approach:

>>> mylis = ['this is test', 'another test']
>>> [item.upper() for item in mylis]
['THIS IS TEST', 'ANOTHER TEST']
