i am trying to call it but i'm missing something because its asking me whethere i have included square(10) or not.
Oops, try again. Did you remember to call square(10) on line 9?
Replace this line with your code. def square(n): """Returns the square of a number.""" squared = n**2 print "%d squared is %d." % (n, squared) return squared # Call the square function on line 9! Make sure to # include the number 10 between the parentheses. square(10)
