Yes of course. It is called module.

file: functioncoll.py

def foo(): pass
def bar(): pass

file program.py
import functioncoll

functioncoll.foo()


Note: functioncoll.py must be in your python search path. One way to 
easily ensure it is in the search path is to put functioncoll.py in the 
same directory as program.py

Note that all the usual tricks with import also works, like
from functioncoll import foo, bar
import functioncoll as fc
