Challenge: Building Functions

Let's introduce ourselves. I've written a function that outputs my name, and your task is to write a function that outputs your name.


              1234567
            
# Define the function `say_my_name`
def say_my_name():
    # The function prints the string `My name is Heisenberg`
    print('My name is Heisenberg')

# Call the function `say_my_name`
say_my_name()

The say_my_name function simply prints the phrase 'My name is Heisenberg' to the screen, and we can call this function to see this output.
