Create a class
__call__
create objects
__new__
# If you return a string __new__, then it will not take their own __init__, but to go __init__ str the
constructor
__init__
When an instance is created initialization properties Methods
Destructor
the __del__
# method is triggered when the memory is released when the garbage collection recovery Example off a space
Take property values
__getattr__
# when using dot obtain an instance property, if the property does not exist automatically call __getattr__ method
to set property values
__setattr__
# When setting instance properties automatically call __setattr__

access existing property
__getattribute__ (Self, name)
# object calls through the point of an existing property values
Length of the vessel
the __len__ (Self)
# Returns the length of the vessel
Container iterator
__iter__ (Self)
# must be included when making this method iterator, especially when the built-in iter () method is called, and when to use for x in container: When a cyclical fashion. Iterator object themselves, they must be self definition __iter__ method returns.
Sequence reversal
__reversed__ (Self)
# When reversed () is called when the behavior sequence may be ordered only if the time to implement it, for example, a list or tuple.
Call behavior in and not in time to test whether the presence of members of the produced
__contains__ (Self, Item)
# If not defined, then Python will iteration container elements to compare one by one, so decided to return True or False
Double-stranded sequence could not find a container element triggered by key
__missing__ (Self, key)
# dict dictionaries have this method, it defines the behavior If you can not find the key trigger in the container. For example d = { 'a': 1 }, when you execute d [ 'name'], d .__ missing __ [ 'name'] will be called.
