Python OOP Tutorial 5: Special (Magic/Dunder) Methods
 
13:50
In this Python Object-Oriented Tutorial, we will be learning about special methods. These are also called magic or dunder methods. These methods allow us to emulate built-in types or implement operator overloading. These can be extremely powerful if used correctly. We will start by writing a few special methods of our own and then look at how some of them are used in the Standard Library. Let's get started.

Python tricks: Using magic (dunder) functions to create list-like objects
 
17:59
In this video I demonstrate how you can use magic functions, sometimes called dunder (double-underscore) functions, to support special list-like syntax in your own objects. Specifically, I will demonstrate __len__(), __contains__(), and __getitem__().

Anjana Vakil - Using and abusing Python’s double-underscore methods and attributes

Anjana Vakil - Using and abusing Python’s double-underscore methods and attributes [EuroPython 2016] [21 July 2016] [Bilbao, Euskadi, Spain] (https://ep2016.europython.eu//conference/talks/using-and-abusing-pythons-double-underscore-methods-and-attributes) Python’s double-underscore ('`__`') methods and attributes go by many names, including “special”, “dunder”, and “magic”. You already use some, like `__init__`, but there are many more! In this talk, we’ll see how dunders can be useful, silly, dangerous, and fun! We’ll trick Python’s arithmetic and comparison operators. We’ll make objects behave like dictionaries and containers. We’ll reduce an object’s memory usage, and speed up membership tests. We’ll even try some naughty function hacks! ----- The curious Python methods and attributes surrounded by double underscores ('`__`') go by many names, including “special”, “dunder”, and “magic”. You probably use some of them, like `__init__`, every day. But that’s just the tip of the iceberg! In this talk, we’ll explore the weird and wonderful world of the double-underscore, and find out how dunders can be useful, silly, dangerous, and just fun! We’ll play pranks on Python’s builtin operators for arithmetic and comparison. We’ll make arbitrary objects behave like dictionaries and containers. We’ll reduce an object’s memory usage, and speed up tests for membership. We’ll even try some naughty function hacks that we should never use in real life! You'll get the most out of this talk if you're already comfortable writing object-oriented Python code. If you already use special dunder magic in your own code, that's excellent! You’ll have a chance to share your tips & tricks with the rest of the audience at the end of the talk. _Talk repo_: [https://github.com/vakila/dunders][1] [1]: https://github.com/vakila/dunders

What's the meaning of underscores (_ & __) in Python variable names?
 
06:01
https://dbader.org/python-tricks ► Make those underscores count and write clean and beautiful Python, by example Leading underscores in Python variable names (for example _foo and __foo) protect developers from naming conflicts. In this video you'll learn how to work with these Pythonic coding conventions and why they exist. A single underscore in front of a variable name (prefix) is a hint that a variable is meant for internal use only. A double underscore prefix causes the Python interpreter to rewrite the variable name in order to avoid naming conflicts in subclasses. Double underscores are also called "dunders" in Python. Watch the video tutorial to see the details of how double underscore name mangling works and how it affects your own Python classes.

Python super function Return a proxy object that delegates method calls to a parent or sibling class of type. class.__mro__ attribute is a tuple of classes that are considered when looking for base classes during method resolution. class.mro() method can be overridden by a metaclass to customize the method resolution order for its instances. It is called at class instantiation, and its result is stored in __mro__. #PythonTutorialforBeginners #ProgrammingKnowledge #LearnPython #PythonCourse -------------------Online Courses to learn---------------------------- Blockchain Course - http://bit.ly/2Mmzcv0 Big Data Hadoop Course - http://bit.ly/2MV97PL Java - https://bit.ly/2H6wqXk C++ - https://bit.ly/2q8VWl1 AngularJS - https://bit.ly/2qebsLu Python - https://bit.ly/2Eq0VSt C- https://bit.ly/2HfZ6L8 Android - https://bit.ly/2qaRSAS Linux - https://bit.ly/2IwOuqz AWS Certified Solutions Architect - https://bit.ly/2JrGoAF Modern React with Redux - https://bit.ly/2H6wDtA MySQL - https://bit.ly/2qcF63Z ----------------------Follow--------------------------------------------- My Website - http://www.codebind.com My Blog - https://goo.gl/Nd2pFn My Facebook Page - https://goo.gl/eLp2cQ Google+ - https://goo.gl/lvC5FX Twitter - https://twitter.com/ProgrammingKnow Pinterest - https://goo.gl/kCInUp Text Case Converter - https://goo.gl/pVpcwL -------------------------Stuff I use to make videos ------------------- Stuff I use to make videos Windows notebook – http://amzn.to/2zcXPyF Apple MacBook Pro – http://amzn.to/2BTJBZ7 Ubuntu notebook - https://amzn.to/2GE4giY Desktop - http://amzn.to/2zct252 Microphone – http://amzn.to/2zcYbW1 notebook mouse – http://amzn.to/2BVs4Q3 ------------------Facebook Links ---------------------------------------- http://fb.me/ProgrammingKnowledgeLearning/ http://fb.me/AndroidTutorialsForBeginners http://fb.me/Programmingknowledge http://fb.me/CppProgrammingLanguage http://fb.me/JavaTutorialsAndCode http://fb.me/SQLiteTutorial http://fb.me/UbuntuLinuxTutorials http://fb.me/EasyOnlineConverter

String Conversion in Python: When to Use __repr__ vs __str__
 
14:58
https://dbader.org/python-tricks ► String conversion in Python classes and other advanced OOP techniques When you define a custom class in Python and then try to print one of its instances to the console (or inspect it in an interpreter session) you get a relatively unsatisfying result. The default "to string" conversion behavior is basic and lacking in detail. By default all you get is a string containing the class name and the `id` of the object instance (which is the object's memory address in CPython). That's better than *nothing*, but it's also not very useful. The solution here is adding the `__str__` and `__repr__` "dunder" methods (some call them "magic methods") to your class. They are the Pythonic way to control how objects are converted to strings in different situations. In this tutorial video I'll do a deep dive on how Python's to-string conversion works and how you can add it to your own custom classes. I'll walk you through the __str__ and __repr__ methods, when to use each, and some tips on how to use them in real world scenarios. Just remember: * The result of `__str__` should be readable. * The result of `__repr__` should be unambiguous. * Always add a `__repr__` to your classes. The default implementation for `__str__` just calls `__repr__`, so you get the best of both worlds.

Python OOP Tutorial 3: classmethods and staticmethods
 
15:20
In this Python Object-Oriented Tutorial, we will be learning about classmethods and staticmethods. Class methods are methods that automatically take the class as the first argument. Class methods can also be used as alternative constructors. Static methods do not take the instance or the class as the first argument. They behave just like normal functions, yet they should have some logical connection to our class. We will look at some examples of both of these in order to understand both in depth. Let's get started.

Method Types in Python OOP: @classmethod, @staticmethod, and Instance Methods
 
14:54
https://dbader.org/python-tricks ► Master OOP techniques in Python with bite-sized code examples What's the difference between @classmethod, @staticmethod, and "plain/regular" instance methods in Python? You'll know the answer after watching this Python video tutorial: Regular (instance) methods need a class instance and can access the instance through `self`. They can read and modify an objects state freely. Class methods, marked with the @classmethod decorator, don't need a class instance. They can't access the instance (self) but they have access to the class itself via `cls`. Static methods, marked with the @staticmethod decorator, don't have access to `cls` or `self`. They work like regular functions but belong to the class's namespace. In this video tutorial I go over the differences between these different kinds of methods in Python. I also explain when to use each with a simple example so you can improve your object-oriented programming (OOP) skills in Python.
