Because _new and _init work together in constructing objects ( _new to create it, and _init to customize it no non-None value may be returned by _init ; doing so will cause a TypeError to be raised at runtime.
An example of a built-in method is alist.
c._len # Explicit lookup via instance Class getattribute invoked 10 type(c)._len c) # Explicit lookup via type Metaclass getattribute invoked 10 len(c) # Implicit lookup 10 Bypassing the _getattribute machinery in this fashion provides significant scope for speed optimisations within the interpreter,.
An objects identity never changes once it has been created; you may think of it as the objects address in memory.Sequences are distinguished according to their mutability: Immutable sequences An object of an immutable sequence type cannot change once it is created.Encode can be used to convert a str to bytes using the given text encoding, and code can be used to achieve the opposite.If the class has a _setattr 4 combo sfp slots or _delattr method, this is called instead of updating the instance dictionary directly.If defined, called to implement isinstance(instance, class).Context managers are normally invoked using the with statement (described in section The with statement but can also be used by directly invoking their methods.When the function executes a return statement or falls off the end, a StopIteration exception is raised and the iterator will have reached the end of the set of values to be returned.However, even when the class definition occurs inside the function, methods defined inside the class still cannot see names defined at the class scope.See also PEP 3119 - Introducing Abstract Base Classes Includes the specification for customizing isinstance and issubclass behavior through _instancecheck and _subclasscheck, with motivation for this functionality in the context of adding Abstract Base Classes (see the abc module) to the language.Special read-only attribute: _dict_ is the modules namespace as a dictionary object.In this case, the cycle will be later detected and deleted by the cyclic garbage collector.The pictures combination stays with the pay line, a line in the middle of a viewing window determine winning or losing.



The extension modules dbm.
Customizing class creation Whenever a class inherits from another class, _init_subclass_ is called on that class.
Class method objects A class method object, like a static method object, is a wrapper around another object that alters the way in which that object is retrieved from classes and class instances.
When the player click the "Spin" button or pull the handle, the computer spins the reels, and finally stops at the various symbols correspond to the number series generated by the random number generator.Winning slots is really a fun.Object._delitem self, key ) Called to implement deletion of selfkey.Note, this mechanism is primarily reserved for use with static type hints, other usage is discouraged.See section Special method names.Function attributes on built-in functions may be supported in the future.These are attributes that provide access to the implementation and are not intended for general use.When an instance method object is created by retrieving a user-defined function object from a class via one of its free slot games on facebook com instances, its _self_ attribute is the instance, and the method object is said to be bound.These methods should attempt to do the operation in-place (modifying self ) and return the result (which could be, but does not have to be, self ).



A module object does not contain the code object used to initialize the module (since it isnt needed once the initialization is done).
If a class that does not override _eq wishes to suppress hash support, it should include _hash_ None in the class definition.
