How to find the positions of the maximum list?

Question from homework: Define a function censor(words,nasty)that takes a list of words, and replaces all words that look in the disgusting word CENSORED, and returns a censored list of words.

>>> censor([’it’,’is’,’raining’], [’raining’])
[’it’,’is’,’CENSORED’]

• find the index nasty

       if word...
