Hi, I am not sure how the constants are implemented in math, but here is how I would do it. The main idea is to declare the constants as globals in some file.
Declare all the constants in a file: const.py --- pi = 3.14 Whenever you want to use pi from another file, just do: somecode.py --- from const import pi a = 2 * pi Regards, Ray Tommy Grav wrote: > I have some code for doing orbital computations.
