Instantiate all functions in Python

Question

Is there a way to do something like this:

util.py contains:
def add
def subtract

instantiate.py contains:
def instantiate

where instantiate does:

import util
def instantiate():
    add = util.add
    subtract = util.subtract

So I can skip typing util everytime I use a function and I can instantiate them all using one function?

I tried but I get

NameError: global name 'util' is not defined

You can import specific functions from a module :

from util import add, substract

I tried doing: def instanciateAll(): from util import countInstanceOf,getAllUnique,getUnique,flames,reverseWord,fstrip,palindrome But still it says the same error, though I could use what you gave me. I could just save a text file somewhere then add a new function then paste it on the Python cmd. Thanks. :)

if you just want to import those functions into the same namespace, you could do something like this:

from util import *

then you can write add and so on without prefixing it with that module

large projects can be a bit harder to read if there are lots of these :-)

If you want a method that adds/subtracts, you should use operator.add or operator.sub.

I was just using add and subtract as an example, plus my question is how can I eliminate the assigning of function names to var names so that I will skip using the name of the import when using the functions, thanks anyway! And yeah I know I should use relevant names ^^
