In Python, different hexadecimal conversion (binary, octal, decimal, and hexadecimal) and python hexadecimal

In my opinion, hexadecimal conversion is indeed a common problem. Therefore, in Python, the following code is also indispensable.

This is an article from the Internet that can also be converted to Python, and can be used after verification. The following is the implementation code:
