Value-Returning Function - Python Programming Exercise

In this exercise, you will develop a Python program where the main function should define and call a sum function that accepts two integers as parameters and returns their sum. This exercise is perfect for practicing function definition, parameter passing, and basic arithmetic operations in Python. By implementing this program, you will gain hands-on experience in defining functions, passing parameters, and performing arithmetic operations in Python. This exercise not only reinforces your understanding of function definition but also helps you develop efficient coding practices for managing user interactions.

Value-Returning Function

 Objective

Develop a Python program where the main function should look like this:

x = 3
y = 5
print(sum(x, y))

You must define the function `sum`, and it will be called from within the main function. As shown in the example, it must accept two integers as parameters and return an integer (the sum of those two numbers).

 Example Python Exercise

 Copy Python Code 
# Define the sum function that accepts two integers as parameters
def sum(x, y):
    # Return the sum of the two integers
    return x + y  # This will return the sum of x and y

# Main function to execute the program
def main():
    # Initialize x and y as 3 and 5, respectively
    x = 3  # x is set to 3
    y = 5  # y is set to 5
    
    # Call the sum function with x and y as arguments, and print the result
    print(sum(x, y))  # This will print the result of 3 + 5, which is 8

# Call the main function to run the program
main()  # This triggers the execution of the sum function and prints the result

 Output
