Regarding exception handling

[Aggelos I. Orfanakos]

Coming from C, I think that it's generally a good programming practice
to make sure everything you create, closes; whether it's about a socket
or a file. This may not be the case with Python though. To be honest,
leaving this task to the garbage collector doesn't sound like a good
idea to me (since the language gives you the means to do it yourself).
