Exploring the Power of Python Functions and Modules
Exploring the Power of Python Functions and Modules Python, renowned for its simplicity and readability, empowers developers with an arsenal of features to enhance code organization and reusability. Among these, functions and modules stand out as fundamental building blocks, playing a crucial role in structuring Python programs. Functions: Modular Code Units Functions in Python encapsulate a set of instructions, promoting code modularity and reusability. Defining a function involves using the `def` keyword followed by the function name and parameters. For example: ```python def greet(name): """A simple function to greet the user.""" print(f"Hello, {name}!") Calling the function greet("John") ``` Here, the `greet` function takes a `name` parameter and prints a greeting. Functions aid in breaking down complex tasks into smaller, manageable units, improving code readability and maintenance. Parameters and Return Values
