I am learning classes and object and I have a problem with this code. Simply does not work. Can you tell me the reason please? Error message tells me that Distance is not defined...(I don´t understand this message)
Thank you for help!
class Distance(object): 'return distance between 2 points' point=Distance() point.x=3.0 point.y=4.0 print_distance(point) def print_distance(d): distance = math.sqrt(d.x**2 + d.y**2) print distance def main(): pass if __name__ == '__main__': main()
