These objects are known as class instances and are created by setting a variable equal to the class name followed by parentheses (): Here, the instance name is my_home, which derives from the Home class. Calling this line implicitly calls the Home class’s __init__ () method. I created a class Toy and want to create a function, getNewToy(name, data1, data2, data3, data4, data5). I want this function to create a new instance of the class Toy, and I want the function to be able to be called multiple times each time creating a new instance. In my experience you create an instance with:This method is run automatically when you create an object of your class. class Person (): def __init__ (self, name): self.name = name. Our __init__ method above requires an argument called name. When we create an object using our Person class, we should pass a name into the call like: Person ("Bob").

This confirmed that method (the instance method) has access to the object instance (printed as <MyClass instance>) via the self argument..

However, a class can only have one initialiser in Python, because that is a special method called within the constructor (the class __new__ method). So when we say a sub class has its own initialiser, we really mean something like this: class Worker(People): def __init__(self, company): self.company = company.
