Find all the sides and angles of a triangle, if you know some of the sides and/or angles. (Uses the Law of Sines and Law of Cosines.)

This little package applies the law of sines or cosines to find all the sides and angles of a triangle, if you know some of the sides and/or angles.
The main function defined by this package is solve(…). Simple example:
from math import pi from trianglesolver import solve a,b,c,A,B,C = solve(b=7.6, c=8.3, A=pi/3)
Following the usual convention, lower-case letters are side lengths and capital letters are angles. Corresponding letters are opposite each other, e.g. side b is opposite angle B.
All angles are in radians! However, you can use the degree constant to convert:
from trianglesolver import solve, degree a,b,c,A,B,C = solve(b=7, A=5*degree, B=70*degree) print(C / degree)
