Hi!
Preparing for an upgrade from 2.7 to 3, I stumbled across an
incompatibility between 2.7 and 3.2 on one hand and 3.3 on the other:
class X(int):

super(X, self).__init__(value)

On 2.7 and 3.2, the above code works. On 3.3, it gives me a "TypeErr

I have two problems that are related and that I'd like to solve together.
Firstly, I have code that allows either a file or a string representing
its content as parameter. If the parameter is a file, the content is
read from the file. In Python 2, I used "isinstance(p, file)" to
determine

Hi!
I can call a staticmethod f() of class C like "C.f()" or with an

General advise when assembling strings is to not concatenate them
repeatedly but instead use string's join() function, because it avoids
repeated reallocations and is at least as expressive as any alternative.

Some updates on the issue:

I noticed yesterday that a single HTTP request to localhost takes
roughly 1s, regardless of the actually served data, which is way too
long. After some digging, I found that the problem lies in

tries the IPv4 127.0.0

I need a little nudge in the right direction, as I'm misunderstanding
