TypeError: can't subtract offset-naive and offset-aware datetimesThis happens because even though the utcnow() function produces adatetime for the UTC timezone, the result is a naive datetime object, and Python prevents you from mixing naive and aware datetime objects. If you are suddenly ...

In earlier versions of Python, a comparison operation such as cmp(a,b) would always produce an answer, even if a user-defined __cmp__() method encountered an error, since the resulting exception would simply be silently swallowed. Work has been done on porting Python to 64-bit Windows ...
