Question: Explain how to return a value from a function in a programming language.
Answer: To return a value from a function, follow these steps:
1. Understand what a function is: A function is a reusable block of code that performs a specific task, simplifying the code and making it easier to maintain and debug.
2. Create a function: Define a function using a function definition statement, including the keyword (e.g., 'def' in Python), function name, a pair of parentheses with input parameters (if needed), and a colon. Then write the function's body, which is the code executed when the function is called.
3. Use the return statement: Include a 'return' keyword followed by an expression or value that you want the function to return. The return statement stops the execution of the function and sends the value back to the point where the function was called.
4. Call the function and get the returned value: Write the function name followed by a pair of parentheses containing any necessary input arguments. Store the returned value in a variable, print it, or use it in further calculations.
