Finding duplicate words in a string python

Question

I am trying to make my function locate duplicate words and if so the output should be True or False depending on wether there are duplicate words. For example:

doubleWord("cat") --> False .      
doubleWord("catcat") --> True .   
doubleWord("contour" * 2) --> True

So far I have this:

def main():

    word = input("Enter a string: ")

    half = len(word) >> 1
    if word[:half] == word[half:]:
        print("True")
    else:
        print("False")

    return
    print(main())

if name == "main": main()

Any help would be greatly appreciated. I thought maybe using slicing would make it easier but I have no idea how to implement that in my code. Thanks!

You just have to compare the first part with the second, you can do this with slicing like this:

def doubleWord(word):
    return word[len(word) // 2:] == word[:len(word) // 2]
