The arguments and the -> describe the type of the function. 

def longestCommonPrefix(self, strs: List[str]) -> str:
    pass

So it takes one argument, strs which is a list of strings (List[str]).
Then it returns a string (str).

    To add to this answer, the `self` argument means this function is a non-static member function of some class – LLSv2.0 Mar 05 '20 at 16:07
