Challenge: Building functions

Let's get to know each other. I wrote a function that will output my name to you, and you will write a function that will output your name.


              12345678
            
# 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()

So, 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.

Task

You have to write a function that prints your name in the console. This function must have no parameters and no return value. The name of the function must be print_name.
