Modules help organize code from "summary" of Python Programming by John M. Zelle
When writing a large program, it's important to keep your code organized. One way to do this is by using modules. Modules are files that contain Python code. By breaking your program into separate modules, you can keep related code together and separate different parts of your program. For example, if you were writing a program to calculate taxes, you might have one module for calculating income tax, another for calculating sales tax, and another for calculating property tax. This way, each type of tax calculation is contained in its own module, making the code easier to understand and maintain. Modules also help prevent naming conflicts. When you import a module into your program, you can refer to its functions and variables using the module name. This helps avoid conflicts with names used in other parts of your program. For example, if you have a function called "calculate_tax" in two different modules, you can differentiate between them by calling them "income_tax. calculate_tax" and "sales_tax. calculate_tax". Another benefit of using modules is code reuse. Once you've written a module, you can easily reuse it in other programs by importing it. This saves you time and effort, as you don't have to rewrite the same code multiple times. It also helps keep your code consistent, as you can use the same module in different programs. In addition, modules can help improve the readability of your code. By organizing your code into separate modules, you can break down your program into smaller, more manageable pieces. This makes it easier to understand how your program works and makes it easier to debug and maintain.- Modules are a powerful tool for organizing your code. By breaking your program into separate modules, you can keep related code together, prevent naming conflicts, reuse code, and improve readability. This can make your code easier to understand, maintain, and debug.
