>>> if ( (str != " ") && (str != "") ):
  File "<stdin>", line 1
    if ( (str != " ") && (str != "") ):

SyntaxError: invalid syntax

Hmmm... it looks like && is a syntax error in Python. That's probably
because Python isn't C or Java or whatever language you're trying to
program in :-)

Python has operators and, or, not that will do what you are trying to do.

You may want to read these first:
