Python: Dynamic Access of Data in Module at Runtime

Question

I have a Python file (myconstant.py) that does not exist when I start my program. It also is located on another machine, but I can access it via Samba. Let's say in it is:

MYCONSTANT1 = 123

My program should be able to access this constant at runtime. I think I need some kind of wrapper, e.g. constant_wrapper:

from myconstant import *

Now I can use constant_wrapper.MYCONSTANT1 in my main program. This unfortunately only works if myconstant.py exists at the beginning of the execution.

How can I dynamically load myconstant.py at runtime without having to write a class that server as some kind of getter but directly accessing the data in it?
