Answering my own question (sorry), this works: def functions(): result = [] for i in range(10): def makefunction(index): def mth(): return index return mth mth = makefunction(i) result.append(mth) i = 25 return result for mth in functions(): print mth() But how will I understand this 3 months from now?

Why do you put the function definitions inside the functions() constructor ? AFAICTL the confusion is caused by this overly complicated nesting which doesn't seem necessary.
