You wouldn't ever put a print statement (or in Python 3 [only] a print function call) inside of a list comprehension. In Python 2, it's illegal, and in Python 3 it's blasphemous. List comprehensions are syntactic sugar for creating lists; if you wish to print said list, you will print the list generated by the list comprehension, so the text "print" ...

In you code, t is always one of s[i:j], and then you test whether it is in the sequence s[i:j], which will always be True. So the "return False" statement will never execute. Further, your function is returning None because there is no other return statement. What you need is to check for each index (so you need for index in ...
