I don't think the function itself matters; what's going on is that if you import it locally, the reference you're using is in the local namespace versus being in a module's namespace, which means it takes less time to get to the function object. I'm guessing the function is being called a fair number of times in a loop or some such similar manner?



You could use `from some_module import some_func` to get the same effect as some_func will be in the local namespace.


That's what the top-level commenter was doing.


Ok. It wasn't clear what "importing it locally" meant. I've worked with some people who would use that phrase to mean "copy paste it into the local file".


Fair point :P. I think I might have seen someone mean it like that as well in the past.


And a common stdlib trick is to bind these via function arguments e.g.

    def foo(a, b, thing=util.thing):
        ...


I agree, seems likely. gp can use dis.dis() to confirm this...
