How can I override a constant in an imported Python module?

Question

In my application I am using module within the package example called examplemod.

My app:

from example imp         


        

Answer 1

This is called monkey patching, and it's fairly common although not preferred if there's another way to accomplish the same thing:

examplemod.config.CONSTANT = "Better value"

The issue is that you're relying on the internals of examplemod and config remaining the same, so this could break if either module changes.
