Calculating board's computation ability

ardfoss:
Hi All,
Generically how do we calculate the amount of memory required to hold c/ python library , which arduino board is suitable.
Do we have a online calculator for these.
For example : haversine formula compute using math library.

No, never heard of such a thing. You need an operating system that's supported by Python to run standard Python, its more than just a language, its a complex software environment. You either have enough disc space or not(!)

Micropython might be more appropriate. Not the same thing though.
