Apologies for breaking threading, but my ISP seems to have eaten the
original post from Tommy. Hence I'm replying to a reply.

If all your code is in the one file, then it couldn't be simpler. E.g.:
# orbital computations
# define some constants
G = 1.0 # gravity is strong in this universe...
# define some functions
def force_of_gravity(m1, m2, r):
return G*m1*m2/r**2
