Python module (1), python module ( During the development of computer programs, as the program code is written more and more, the code in a file will become longer and longer, making it increasingly difficult to maintain. In order to write maintainable code, we divide many function groups into different files, so that each file contains less code, many programming languages use this method to organize code.
