2. A detailed description of the mathematical and random numbers in the Python standard library (math package, random package)

Summary: We have seen Python's most basic mathematical functions in Python operations. In addition, the math package complements more functions. Of course, if you want more advanced math features, consider choosing NumPy and scipy projects outside of the standard library, which not only support array and matrix operations, but also have a wealth of mathematical and physical equations to use.
