What is instantiation in the context of object-oriented programming?

How is an object instantiated in Python when the constructor requires no parameters?

What does the term 'literal form' refer to in Python's object instantiation?

When would you use a syntax like 'Widget(a, b, c)' for instantiation?

How can a new instance of a list class be created indirectly in Python?

Which of the following is NOT mentioned as a method for creating new instances in Python?

Instantiation in Object-Oriented Programming

Instantiation in OOP creates an object from a class, where the object is an instance of the class

Object Instantiation in Python

In Python, an object is instantiated by calling the class as a function and passing in any required arguments
If the constructor requires no parameters, an object is instantiated by calling the class without arguments, e.g., MyClass()

Literal Form in Python

In Python, literal form refers to the direct creation of an object, e.g., list() or 10 for an integer
Literal form is a concise way to create objects in Python

Syntax for Instantiation

The syntax Widget(a, b, c) is used for instantiation when the class constructor requires arguments, e.g., a, b, and c

Creating a List Instance in Python

A new instance of a list class can be created indirectly in Python by using the list() function or by using the literal form, e.g., []

Methods for Creating New Instances in Python

The following are methods for creating new instances in Python: literal form, direct creation using the list() function, and calling the class as a function
Using __new__ method is NOT mentioned as a method for creating new instances in Python

Learn about the process of creating a new instance of a class through instantiation in object-oriented programming. Understand the syntax for instantiating an object by invoking the constructor of a class with or without parameters.
