I think you would benefit from reading the data into a numpy array first,
then using numpy min, max functions.

Looking for tips and lessons learned (advice on what to do and
not do) for writing a Python based DSL.
Googling python dsl yields some wonderful content which I've just
started to read. If there are specific articles or 3rd party
libraries that you used to implement a DSL, I would appreciate
heari
For me, diving into the data model really helped me grasp some of the
metaprogramming capabilities that python has, which is helping me as I am
implementing my own DSL in python.
