What are some examples of objects in Python?

Everything is in Python treated as an object, including variable, function, list, tuple, dictionary, set, etc. Every object belongs to its class. For example - An integer variable belongs to integer class. An object is a real-life entity. An object is the collection of various data and functions that operate on those data.

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.
