Python (object instance attribute)

Scope of the problem category

The reference (.) Is a partial, inside the class will not exceed the scope of the class body, there is no reference (.) Is global

Modify the properties of the instance (by instance name) and the attribute class (with instance names) to distinguish

# - * - Coding: UTF-. 8 - * - 
class CAR: 
    'This is a car class' instructions # class 
    wheel = 'rubber' 
    Engine = 'engine' 
    DEF the __init __ (Self, License, Brand,. Price): # must be initialized so many (__init__), return automatically 
        # self generated dictionary 
        self.Licenses = License 
        self.brands = Brand 
        self.prices. price = 
    DEF Transport (self): 
        Print ( 'pull cargo --- ---') 
    DEF Manned (Self): 
        Print ( 'manned --- ---') 
    # parameterized method 
    DEF colors (Self, color): 
        Print ( '% S --- color is% s ---'% (self. the Licenses, Color)) 

CAR1 CAR = ( '123456', 'mass', '100,000') 
# change merely examples of 
car1.wheel = 'wheels. 1' 
Print (CAR.__dict__)
print(car1.wheel)
# Class is changed 
car.wheel = 'wheels 2' 
Print (CAR .__ dict__ magic)

Example Modify the modified class member variables

    wheel = 'rubber' 
    Engine = 'engine'

    reference method # with 
    DEF colors (Self, color): 
        Print ( "% color --- s. --- is S% '% (self.Licenses, Color))

# reassigned to the instance variable
