How do you return a value from a function?

Short Answer

Expert verified

Question: Explain how to return a value from a function using a step-by-step process. Answer: To return a value from a function, follow these steps: 1. Define a function: Use the "def" keyword, function name, parentheses, and a colon (e.g., def add_numbers(number1, number2):). 2. Write the function body: Add the code required for the desired task (e.g., result = number1 + number2 to add two numbers). 3. Use the return keyword: Add "return" followed by the value or variable to be returned (e.g., return result). 4. Call the function and store the returned value: Call the function with the appropriate arguments and store the returned value in a variable (e.g., sum_result = add_numbers(3, 5)).

Step by step solution

Define a Function

To return a value from a function, first, we need to define a function. A function is a block of reusable code that performs a specific task. Functions are defined using the "def" keyword, followed by the function name, parentheses, and a colon. For example, we can define a function named "add_numbers" to add two numbers. ```python def add_numbers(number1, number2): ```

Write the Function Body

Inside the function, write the code needed to perform the task. In our example, we want to add two numbers, so we need to add "number1" and "number2" together. ```python def add_numbers(number1, number2): result = number1 + number2 ```

Use the Return Keyword

To return a value from a function, use the "return" keyword, followed by the value or variable you want to return. In our example, we want to return the result of adding "number1" and "number2", so we use the "return" keyword followed by the "result" variable. ```python def add_numbers(number1, number2): result = number1 + number2 return result ```

Call the Function and Store the Returned Value

To use the function and obtain the returned value, call the function by its name, followed by the arguments inside the parentheses. Assign the function call to a variable to store the returned value. ```python sum_result = add_numbers(3, 5) print(sum_result) # It will output 8 ``` This way, we have returned a value from a function.
