So the code below works for all test cases on my edx course and even works on Python tutor yet for some reason it doesn't work for this one single test case:
def isWordGuessed(secretWord, lettersGuessed):
    for i in range(len(secretWord)):
        if secretWord[i] in lettersGuessed:
            return True
        else:
            return False
            break
Test case is:
secretWord = 'apples'
lettersGuessed  = ['a', 'e', 'i', 'k', 'p', 'r', 's']
isWordGuessed(secretWord, lettersGuessed)
Should return False, but it returns True.
