math - Is the golden ratio defined in Python?

Question

Is there a way to get the golden ratio, phi, in the standard python module? I know of e and pi in the math module, but I might have missed phi defined somewhere.

Answer 1

scipy.constants defines the golden ratio as scipy.constants.golden. It is nowhere defined in the standard library, presumably because it is easy to define yourself:

golden = (1 + 5 ** 0.5) / 2
