I am just a newbie but the following code works for me (on linux, hence 
the #! first line)

#!/usr/bin/env  python
import string,math
#Import string for the atoi function, since raw_input returns a string
#Import math so pi has many digits :)

radius=string.atoi(raw_input('Radius? '))
circ = 2*math.pi*radius

print circ

#Or to print circ to only 2 places

print 'Circumference is %.2f'%circ
