Si te gusta más puedes declarar los métodos poniendo def __init__(objeto, a, b, c) y luego dentro objeto.a=2, etc. Funcionará perfectamente pues lo único que espera python es que el primer parámetro (se llame como se llame) contenga una instancia de ese objeto.

How can we use "__init__ " ? One of the most widely used and one of the most misunderstood is init in python. Python is one of the object-oriented paradigm (everything you create is an object), and init in python terminology is known as a constructor. Don’t worry if you don’t know what is object-oriented programming or you don’t know about constructors.

Looking for a concise but thorough explanation of what Python 3's self means? What __init__() in classes does? What Class Objects and Instance Objects are an

It binds the instance   15 Dec 2019 class Foo: def __init__(self, value_a, value_b): self.a = value_a self.b = value_b foo = Foo(7, 9) # __init__ is called print(foo.a , foo.b) # 7 , 9. The reserved Python method __init__() is called the constructor of a class. You can call the constructor method to create an object (=instance) from a class and  Here, we define the __init__ method as taking a parameter name (along with the usual self ). Here, we just create a new field also called name .

Python is one of the object-oriented paradigm (everything you create is an object), and init in python terminology is known as a constructor. Don’t worry if you don’t know what is object-oriented programming or you don’t know about constructors. def __init__ I think I understand it is defining a method called "init" - but what's with all the underscores. Or is it some builtin method of Python? Sorry - confused Cheers!

Sorry - confused Cheers! __init__ is the function that is called automatically upon an object's construction: The instance method __init__() is the initializer of a class.

def __init__(self,driver) 写一个构造函数，有一个参数driver init相当于构造方法，初始化就会自动调用 在调用class类时，如果有 构造函数，它和class调用本身没有关系，而和class的调用的地方有关系，如果在def内部去调用，则使用self的方式，如果在def外部去调用，括号中的值则可以是外部传入的值。

Use the __init__() function to assign values to object properties, or other operations that are necessary to do when the object is being created: 2019-11-21 The double underscore “__” (called “dunder“) is used to make an instance attribute or method private (cannot be accessed from outside the class) — when used as leading dunder. When used as enclosing dunder (e.g. “__init__”) it indicates that it is a special method in Python (called “magic method”). def __init__(self, something): _something = something The something parameter would be stored in variables on the stack and would be discarded as soon as the __init__ method goes out of scope. How __init__ works with Inheritance? When we have a class inheriting from a … def __init__(self): self.data = [] When a class defines an __init__() method, class instantiation automatically invokes __init__() for the newly-created class instance. So in this example, a new, initialized instance can be obtained by: x = MyClass() Of course, the __init__() method may have 2017-05-05 Class with No Constructor.
