I keep on getting the no attribute error in python. I want to make a class for cities to put into a program I am writing (Im trying to learn python on the side while working). I basically want to be able to put data into a class for cities and use that in another place. I guess, I would need to know how to access attributes from a class. Im probably doing a bunch wrong so any feedback would be helpful
class City:
def __init__(self, name, country, re_growth10):
self.name = name #name of the city
self.country = country #country the city is in
self.re_growth10 = re_growth10 #City Real estate price growth over the last 10 years
def city_Info(self):
return '{}, {}, {}'.format(self.name, self.country, self.re_growth10)
Toronto = City("Toronto", "Canada", 0.03) #Instance of CITY
Montreal = City("Montreal", "Canada", 0.015) #Instance of CITY
user_CityName = str(input("What City do you want to buy a house in?")) #user input for city
def city_Compare(user_CityName): #Compare user input to instances of the class
cities = [Toronto, Montreal]
for City in cities:
if City.name == user_CityName:
print(City.name)
else:
print("We Don't have information for this city")
return ""
print(City.name)
You are getting confused because you have a variable that has the same name as your class, City
. To avoid this, use lower-case names for variables. Once you change this, you get a different error:
NameError: name 'city' is not defined
The reason is that you are trying to print the name of a variable which is defined inside a function , but the print
statement is outside the function. To fix this, put your last print
statement inside the function city_Compare
, and call that function (which you never do).
Or change the function to return
an object instead of printing it:
def find_city(name):
cities = [Toronto, Montreal]
for city in cities:
if city.name == name:
return city
return None
city_name = input("What City do you want to buy a house in?")
city = find_city(city_name)
if city is not None:
print(city.name)
else:
print("We Don't have information for this city")
