"doesn't work" is the most useless possible description of a problem. As a general rule, please: - post the minimal running code that exhibit the problem - clearly state the result you hoped and the result you got. Also, don't use builtin names as identifier. "str" is the string type, so using "str" as an identifier will shadow the str type. And, finally, you don't even need multiple conditions here - this should be enough (using 'my_string' instead of 'str'): if my_string.strip() : ... In Python, an empty sequence (strings, lists, tuples, ...), an empty mapping (dict, ...), the integer 0 and the float 0.0 are all evalued to False in a boolean expression. So any non-empty string evals to True. The method strip() of type str returns a copy of the string with leading and trailing whitespaces removed, so " ".strip() will return "".
