Difference between 'function' and 'method'

Howdy everyone, This is a big problem puzzles me for a long time. The core question is: How to dynamically create methods on a class or an instance? Let me state it step by step. 1. def gunc(self): pass class A(object): def func(self): pass a = A() a.func # gives "bound met

Removing default logging handler (causes duplicate logging)

Hello All, I want to add a logger to my application, then addHandler to it to log to a special destination. Unfortunately when I use logging.getLogger("my_logger") to create the new logger, it apparently comes with a default handler that logs to STDOUT (or STDERR?). When I add my special handler

So far in Python I've almost hated the 'else' of the 'for' loops: - I have problems to remember its meaning; - It gives me little problems when I later want to translate Python code to other languages (and you always have to translate long-lived code). - I have used it only once, so far. So so far
