Just in case: this warning comes from the types of '' and None being different. >>> 1.0 is 1 <stdin>:1: SyntaxWarning: "is" with a literal. Did you mean "=="? False One can compare objects of different types for equality: >>> type(1.0) <class 'float'> >>> type(1) <class 'int'> >>> 1.0 == 1 True (it's the same with "is not" vs. "!=") Best, Dima
