Fixed format of object-oriented definitions and calls

class class name: 
    DEF the __init __ (Self, parameter 1, parameter 2): 
        Self properties of the object 1 = parameter 1. 
        Self properties of the object 2 = parameter 2. 

    DEF method name (Self): Pass 

    DEF method name 2 (self): pass 

object name = name of the class (2) # is the object instance represents a specific thing 
                  # class name (): + class name in parentheses is an instance of a class, a method is equivalent to calling the __init__ 
                 # pass parameters in parentheses , parameters do not need to pass self, other participants in the form of one-init 
                   # result returns an object 
object name. properties object # 1 to view the object directly with the object name. attribute name to 
an object name. method name ( ) # call the class method, direct method name with the name of the object () to
