how can I import a module without using pythonpath?

Hi, I'm using python 2.2, I want to import a module by referring to its relative location. The reason for this is that there is another module with the same name that's already in pythonpath( not my decision, but I got to work around it, bummer). So is there any easy way to do it? something lik

Iteration within re.sub()?

Hi, Is it possible to perform iteration within the re.sub() function call? For example, if I have a string like: str = "abbababbabbaaa" and I want to replace all b's with an integer that increments from 0, could I do that with re.sub()? Replacing b's with 0's is trivial: i = 0 pat = re.compil
