python - I am getting an EOF error and don't know how to fix it -

i trying write program fits these rules:
lease , it’s time move. unfortunately, have lot of stuff , don’t want spend time moving because you’d rather practicing programming skills. thankfully, have friends can help, though comes @ cost. friends can move 20 boxes hour, require 1 16 inch (diameter) pizza work. write function in python takes number of boxes have , returns how square feet of pizza have buy. use function header: sqftpizza(numboxes)

and have return square feet of pizza float.

this code have

def sqftpizza(numboxes):     = 3.14159*(8*8)     c = 1/12**2     sqft = * c     za =numboxes/20     area = za * sqft     print (area) def question():     numboxes= float(int(input("how many boxes have?: " )))     sqftpizza(numboxes) question()  

please help?

making function name pep8-compliant,

# --- python 2.x --- __future__ import division          # make int/int return float math import pi  pizza_per_box = pi * (8 / 12)**2 / 20    # 1 16" pizza per 20 boxes  def sq_ft_pizza(num_boxes):     """     input:  number of boxes moved     output: square feet of pizza feed movers     """     return pizza_per_box * num_boxes  def main():     num_boxes = float(raw_input("how many boxes must move? "))     print("you need {:0.2f} square feet of pizza!".format(sq_ft_pizza(num_boxes)))  if __name__ == "__main__":     main() 

which runs like

how many boxes must move? 120 need 8.38 square feet of pizza!
