When programming in a multitude of languages with an aim to get the job done, small details are often missed. It's a trade-off. Today, while preparing for a Python certification exam, I have discovered, that Python's standard library math module has three incredibly useful functions which, in my experience, people (yours truly as well) tend to write themselves.
math.degrees(x)converts angle x from radians to degrees.math.radians(x)converts angle x from degrees to radians.math.hypot(*coordinates)returns the Euclidean norm,sqrt(sum(x**2 for x in coordinates)). This is the length of the vector from the origin to the point given by the coordinates.
