How to import variables from another file where the filename itself is a variable

Question

If I have a file called input_file.py and I want to import some variables into another script I use the following:

from input_file import (VarA, VarB, VarC)

If I wanted to have the file name itself be a variable which I could easily switch how would I do it? As an example:

file_name = 'input_file'

from file_name import (VarA, VarB, VarC)

It is not recommended to clutter/clobber the global namespace and you should look at what @MatthewMoore pointed to.

Having said that, you can do this:

import importlib
globals().update(importlib.import_module(file_name).__dict__)
