That's not your problem, that's the caller's problem. He shouldn't be calling import * unless he wants to import everything in your module directly into his namespace. If the caller said to you: "After executing len = x, I can't access the built-in len function any more, can you change x so that it magically tells when I want the built- in behaviour and does that?" you'd probably tell him to get lost. Doing import * is no different. It only becomes your problem if you have advised people that the right way to use your module is with import *. > Is there any way to get rid of the problem (somehow automatically > determine which func should be used - numpy or Python max)?
