Based on the name of the function, it seems that we're supposed to only print the value of quantity to the console.
def show_value(quantity):
print(quantity)
show_value(12)
The first line of code creates the function, the second line of code prints the value of quantity to the console, and the last line of code calls our show_value function with 12 as our argument. I wrote my code in python 3.8. I hope this helps.
