Thanks for mentioning the python version and OS.

You don't have any whitespace at the beginning nor end of the string 
bound to sentence.  So there's nothing to strip.  By the way, if you're 
checking such a function, it's sometimes more informative to write
    print(repr(sentence))
which will add quotes at begin and end, and show newlines and tabs as 
escape sequences.

If you only want to strip from one end of the string, you'd use lstrip() 
or rstrip().

If you're also trying to remove characters from the middle of the 
string, you might use translate() or the string method replace().  For 
example, to remove all spaces from a string, use
     sentence.replace(" ", "")
