How can I cause a Memory Error in python 2.7?

I'm working on a system that has about 128KB of RAM, one of my scripts occasionally causes a ERRNO 12 Cannot Allocate Memory error.

I have a few solutions I want to test.

But how can I replicate the problem when it seemingly happens randomly once a day?

Any bad scripts that will cause ERRNO 12 Cannot Allocate Memory error?

Most posts are trying to solve Memory errors, I want to cause one to test the robustness of my code.

If you want to force Python to run out of memory, this should make it happen very quickly regardless of how much memory is available:

x = [None]
while True:
    x += x

This will double the length of x on every iteration until it fails.
