How do you define a function in Python?

As an experienced Python Training tutor registered on UrbanPro.com, I understand the importance of providing clear and concise explanations to beginners. Defining a function in Python is a fundamental concept, and I'll break it down for you step by step. Definition of a Function in Python: A function in Python is a reusable block of code that performs a specific task or set of tasks. It allows you to organize your code into modular components, making it easier to understand, debug, and maintain. Syntax for Defining a Function: To define a function in Python, you can use the following syntax: python def function_name(parameters): # Code block or statements return result def: Keyword indicating the start of a function definition. function_name: Name of the function, following Python naming conventions. parameters: Input values the function accepts (if any). :: Colon to indicate the start of the function body. Code block: Set of statements that define the function's behavior. return: Keyword to specify the value the function returns (if any). Example: Consider a simple example of a function that adds two numbers: python def add_numbers(a, b): sum_result = a + b return sum_result Here, add_numbers is the function name, and it takes two parameters (a and b). The function adds these parameters and returns the result. Key Points to Remember: Function Name: Choose a meaningful and descriptive name for your function. Follow Python naming conventions to enhance code readability. Parameters: Parameters are optional but allow you to pass values to the function. They are enclosed in parentheses and separated by commas. Function Body: The body of the function contains the code that performs the desired task. Use proper indentation to define the scope of the function. Return Statement: The return statement is optional and specifies the value the function sends back. If omitted, the function returns None by default.
