NameError – function doesn't recognize imported modules

[Sir]

1. as asked by @ndc85430 - why would you import like this in the first place?

For building my own understanding, buran.
As I have written in the beginning: "I was trying out using keywords encoded in a string by using exec() and eval() functions.". Also wanted to make modules transcend the scope zone as a part of the experiment.


I think bowlofred answer is the key here.
But I would like also to acknowledge you for this script with importlib.

Again thank you.
