Chapter 5: Functions and Modules of Python
Abstract : The Python Functions provide the basic building blocks of functionality in larger programs (and computer simulations), and help to control the inherent complexity of the process . We can group functions together into a Python module, and in this way create our own libraries of functionality. Let's explore functions and modules in Python: Functions: What they are: Blocks of reusable code that perform a specific task. How to define them: Use the def keyword followed by the function name and parentheses for parameters. How to call them: Use the function name followed by parentheses with any required arguments. Example: Python def greet(name): print("Hello, " + name + "!") greet("Alice") Modules: What they are: Files containing Python code, including variables, functions, and classes. Why they are useful: They help organize code, promote reusability, and prevent naming conflicts. How to import them: Use the import keyword followed ...
