c. class Point: def __init__(self, x, y): self._x = x self._y = y The __init__ method gets called when memory for the object is allocated: x = Point(1,2) It is important to use the self parameter inside an object’s method if you want to persist the value with the object. If, for instance If a class implements the __str__ method, Python will call the __str__ method when you pass an instance of the class to the str (). For example: class Person: def __init__(self, first_name, last_name, age): self.first_name = first_name self.last_name = last_name self.age = age def __repr__(self): return f'Person ("{self.first_name}","{self.

It is known as a constructor in OOP concepts.

__init__() initializes the state for the object. Meaning, it is a place where we can set out initial or primary state of our object. def __init__ (self, name, age): self. name = name self.

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?

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”).
