How do you create an object in Python?

In Python, we use classes to create objects. A class is a tool, like a blueprint or a template, for creating objects. It allows us to bundle data and functionality together. Since everything is an object, to create anything, in Python, we need classes.

How do you create a class in Python?

In python a class is created by the keyword class. For example, let's create a simple, empty class with no functions. The keyword class is followed by the class name whose first letter is capitalized and then comes a colon to end the class definition and declaration.

How do you call a method in Python?

When we call a method of this object as myobject.method (arg1, arg2), this is automatically converted by Python into MyClass.method (myobject, arg1, arg2) – this is all the special self is about. The __init__ method is similar to constructors in C++ and Java. Constructors are used to initialize the object’s state.
