I did something like this, feel free to use my code:

https://github.com/brian-team/brian2/blob/master/brian2/parsing/rendering.py

At the moment, it only works for series of mathematical statements (no
control conditions, loops, array notation, etc.), but it would be pretty
easy to add those. It also puts too many parentheses in outputted
expressions, e.g. 1+2+3 would come back as (1+2)+3, etc.
