As you might have guessed, the answer is to use a module. A module is basically a file that contains all of the functions and variables you define. In order to reuse modules in other programs, the file name of the
first, the meaning of the moduleIn the development of computer programs, as the program code more and more, in a file code will be more and more long, more and more difficult to maintain.In order to write maintainable code, we grouped many functions into separate files so that each file contained relatively few code, and many programming languages used this way of organizing code. In Python, a. py file is called a module. There are three types of mod
Modules are a core concept of the Python program architecture, and larger programs are often presented as multiple module files, and a module is designed as a master file or a top-level file to launch the entire Python program.
