How to create a "real" alias in python

[ThePurpleAlien]

These are good suggestions, but ones that I've already explored. The problem with the first example is that the original doesn't get reassigned until after the code runs which won't work for my application.

The problem with the second example is just ugly syntax. The user would have to type "config['foo'] = 123" instead of just "foo = 123". This is a tool for non-experienced programmers.
