The math and cmath modules say this in their docs: "This module is always available."  This lead a beginner to believe they didn't need to be imported.

Nearly the entire standard library is always available in this sense (they can be imported).  This sentence isn't useful.

Can we change the first paragraph of the math module to be:

"This module provides access to the mathematical functions defined by the C standard."

(and similarly for the cmath module.)
