can i import predefined function in python 3

In python 3 can i import any modules. like,

import copy

l = range(10)

lst = copy.deepcopy(l)

We can import standard modules (collections, itertools, etc).

Never tried to import the copy module, but it should work.
Just don’t try to do stuff like accessing the file system or other things that would try to mess up the judge machine (the judge is protected against these but it’s against the rules).
