it says NameError: sys
Here is the program I am writing (to cheat on my algebra homework when 
they want me to make tables of quadratic functions.)
I want to be able to type:
./prog a b c min max inc
and have it print a pretty table

#!/usr/bin/python
from sys import argv

a=sys.argv[1]
b=sys.argv[2]
c=sys.argv[3]
start=sys.argv[4]
end=sys.argv[5]
inc=sys.argv[6]



x=start
for x in range(start,end,inc):
  y=a*x**2+b*x+c
  print x,": ",y
