how to edit each member of a list in python

Question

I am new to python and I am trying to create a capitalize function that either capitalizes all words in a string or only the first word. Here is my function

def          


        

Answer 1

Use a list comprehension:

def capitalize(s, applyToAll=False):
    if applyToAll:
        l = [w.capitalize() for w in s.split()]
        return " ".join(l)
    else:
        return s.capitalize()

what do yo guys use in python to debug?

print statements for complicated pieces of code, the interactive interpreter for anything else. I write a lot of tests through, and run them with nose.
