<__main__. object at 0x02C08790> PYTHON -


i new python , have saw question before none of answers have worked me. keep getting 

<__main__.camera object @ 0x02c08790>

and don't know why! code below , appreciate if @ , tell me how make sure sure flows correctly! edit: code go calc_speed counter , calc_speed in loop , sorry indentation errors

class camera():     distance = 2     speed_limit = 20     number_of_cars = 0      def calc_speed(self):         registration = input("registration plate: ")         speeding_list=[]         start = float(input("start time: "))         end = float(input("end time: "))         speed = self.distance/(end-start)         print(("average speed: ") + str(round(speed, 2)) + (" mph"))         if speed > self.speed_limit:             list3= [str(self.registration)]             speeding_list.append(list3)             print("vehicles caught speeding: " + str(speeding_list))             return(program.counter())         else:             print("vehicle not speeding")             return(program.counter())      def counter():         self.number_of_cars = self.number_of_cars + 1         print("number of cars recorded: " + str(self.number_of_cars))                                          return(program.calc_speed())    program = camera() print(program)

when print object, shows object id (like <__main__.camera object @ 0x02c08790>), totally indecipherable mortals. can around defining __str__ or __repr__ function display data instance in custom way.

in case:

def __repr__(self):     return "<__main__.camera: distance = " + str(self.distance) + "; speed_limit = " + str(self.speed_limit) + "; number_of_cars = " + str(self.number_of_cars) + ">"

if there instance of camera starting variable values, return

"<__main__.camera: distance = 2; speed_limit = 20; number_of_cars = 0>".

the <__main__.camera object @ 0x02c08790> how system remembers it, aside showing type of object is, it's useless.
