What is the difference between declaring data attributes inside or outside __init__
- by user1898540
I'm trying to get my head around OOP in Python and I'm a bit confused when it comes to declare variables within a class. Should I declare them inside of the __init__ procedure or outside it? What's the difference?
The following code works just fine:
# Declaring variables within __init__
class MyClass:
def __init__(self):
country = ""
city = ""
def information(self):
print "Hi! I'm from %s, (%s)"%(self.city,self.country)
me = MyClass()
me.country = "Spain"
me.city = "Barcelona"
me.information()
But declaring the variables outside of the __init procedure also works:
# Declaring variables outside of __init__
class MyClass:
country = ""
city = ""
def information(self):
print "Hi! I'm from %s, (%s)"%(self.city,self.country)
me = MyClass()
me.country = "Spain"
me.city = "Barcelona"
me.information()
