How to express this mathematical equality in python

Question

How do I do this calculation in python?

This is what I tried but I guess it's wrong:

 v=(pow(g,s,p)*pow(modinv(b, p), h, p))%p

Unless you know that `v < p`, you need to `%p` _both_ sides. — khelwood, Dec 21 '18 at 15:50

Much simpler than that. Try like this:

v = (pow(g,s) * pow(b,-h)) % p

That's an assignment, not an equality. Also, "simpler", but also less efficient. Those additional functions OP is using are for making `pow` much faster for large numbers if you want to take the modulus anyways. – tobias_k Dec 21 '18 at 15:47
