Learning Python and stuck on script

Hi Guys,

I have started to learn Python and I'm completely lost. I wanted to create an object oriented script that would calculate trip cost but I'm getting the wrong output. Can someone please tell me what I'm doing wrong and how i can correct my program below? When I try to get the return of my function Mileageprice_per_gallon I get some weird output like:

<bound method TripCost.Mileageprice_per_gallon of <__main__.TripCost instance at 0x7f28fe0701b8>>

Open in new window


#!/usr/bin/python

class TripCost:
	def __init__(self, miles_per_gallon, distance, price_per_gallon):
		self.miles_per_gallon = miles_per_gallon
		self.distance = distance
		self.price_per_gallon = price_per_gallon
	def Mileageprice_per_gallon(self):
		return (price_per_gallon * distance)


trip1 = TripCost(22, 13.5, 3.27)
print trip1.Mileageprice_per_gallon

Open in new window

Add parentheses to the function call.

e.g.

print trip1.Mileageprice_per_gallon()

Also, you need to include self when referencing the class-level fields within your Mileageprice_per_gallon method.

e.g.

def Mileageprice_per_gallon(self):
		return (self.price_per_gallon * self.distance)

Also, use 4 spaces for one indentation level. I suggest not to use tab for indentation. Your editor can be set to use spaces instead of tabs, or to indent by spaces.

As kaufmed wrote, the self must be used explicitly.

If not forced to use Python 2.x, you should probably start with Python 3.
