It's alr fixed by Volie (see comment above)

For Python, I first wrote one without the recursive method. It passed all the tests, but it gave me an error about memory. So then I switched my solution to the recursive method. It passed all the tests, but when I submitted it, it gave some error message. It ran fine in my own computer's command line interface with Python.

boo

really fun. so many different unexpected problems that came up. pretty complex/realistic toy problem

I only wrote the original Ruby, Javascript, and Coffescript versions, but I have looked at the Python example solution and tests and they appear fine to me.

What problem are you having with your solution?

Have you looked at previous discussions below?

please fix this for python or at least give a hint as to why so many solutions that actually work just fine in IDLE do not work for the tests

awesome. really fun
