I don't want to fill my HD to find out :) What I want is to know who to catch each exception, so my code can say something to the user when he is trying to write to a ReadOnly FS and another message if the user...

Is it considered as a good practice to pick Unicode string over regular string when coding in Python? I mainly work on the Windows platform, where most of the string types are Unicode these days (i.e. .NET String, '_UNICODE' turned on by default on a new c++ project, etc ). Therefore, I tend to think that the case where non-Unicode strin...

While looking at that file, I found the following pattern appears a lot of times: an internal method (hinted by the leading "_" in the method name) is defined, then a public method is defined just to be the internal method...

I don't think so, but I thought I'd ask just in case. For example, for use in a class that encapsulates an int: i = IntContainer(3) i + 5 And I'm not just interested in this int example, I was looking for something clean and general, not overriding every int and string method.
