Let me introduce you to set(). A set is a like a list but it can only contain unique members. You can make a set with set(<list>).

So take all of the words in the file into a list. Then make a set of that list. If they have different len()s, there are some duplicated words.

Many ways to do it. Here's one:

def duplicate(text):

words = text.split()

words2 = []

for word in words:

    if word in words2:

        return True

    else:

        words2.append(word)

return False

def duplicate(text):

words = text.split()

for word in words:

    if text.count(word) > 1:

        return True

return False
