Functions: Hello and Goodbye - Python Programming Exercise

In this exercise, you will develop a Python program where the main function should look like this: SayHello() and SayGoodbye(). You must define the functions SayHello and SayGoodbye, and they will be called from within the main function. This exercise is perfect for practicing function definition and calling in Python. By implementing these functions and calling them from the main function, you will gain hands-on experience in handling function definitions and calls in Python. This exercise not only reinforces your understanding of functions but also helps you develop efficient coding practices for managing user interactions.

Example Python Exercise

Show Python Code

Copy Python Code

# Define the function SayHello
def SayHello():
    # Print a greeting message
    print("Hello, welcome to the program!")  # The greeting message is printed when SayHello() is called

# Define the function SayGoodbye
def SayGoodbye():
    # Print a goodbye message
    print("Goodbye, thank you for using the program!")  # The goodbye message is printed when SayGoodbye() is called

# Main function to execute the program
def main():
    # Call the SayHello function to display the greeting message
    SayHello()  # This will output: "Hello, welcome to the program!"
    
    # Call the SayGoodbye function to display the goodbye message
    SayGoodbye()  # This will output: "Goodbye, thank you for using the program!"

# Call the main function to run the program
main()  # This triggers the execution of SayHello and SayGoodbye

Output

Hello, welcome to the program!
Goodbye, thank you for using the program!
