Immutable objects are common in functional programming, while mutable objects are widely used in object-oriented programming. Because Python is a multiparadigm programming language, it provides mutable and immutable objects for you to choose from when solving a problem.
May 21, 2024 · Mutable and immutable objects are handled differently in Python. Immutable objects are quicker to access and are expensive to change because it involves the creation of a copy. Whereas mutable objects are easy to change. The use of mutable objects is recommended when there is a need to change the size or content of the object.

In Python, everything is an object. An object has its own internal state. Some objects allow you to change their internal state and others don’t. An object whose internal state can be changed is called a mutable object, while an object whose internal state cannot be changed is called an immutable object. The following are examples of immutable obje...
When you declare a variableand assign its an integer, Python creates a new integer object and sets the variable to reference that object: To get the memory address referenced by a variable, you use the id() function. The id()function returns a based-10 number: Output: And to convert the base-10 number to hexadecimal, you can use the hex()function: ...
The following defines a listof numbers and displays the memory address of the list: Behind the scene, Python creates a new list object and sets the ranksvariable to reference the list: When you add a number to the list like this: Python directly changes the value of the list object: And Python doesn’t create a new object like the previous immutable...
It’s important to understand that immutable objects are not something frozen or absolutely constant. Let’s take a look at an example. The following defines a tuplewhose elements are the two lists: Since the rankingsis a tuple, it’s immutable. So you cannot add a new element to it or remove an element from it. However, the rankings tuple contains tw...
An object whose internal state cannot be changed is called immutable for example a number, a string, and a tuple.An object whose internal state can be changed is called mutable for example a list, a set, and a dictionary.Nov 11, 2020 · Mutable and immutable objects in Python. We have said that everything in Python is an object, yet there is an important distinction between objects. Some objects are mutable while some are immutable. As I mentioned before, this fact causes confusion for many people who are new to Python, so we are going to make sure it's clear.
Nov 9, 2011 · In Python, think of variables as objects containing pointers to other objects, where everything is an object, and each object contains a bit specifying whether it is mutable or immutable, and mutable variables are passed by reference whereas immutable variables are passed by value.
Aug 12, 2024 · Mutable means the ability to modify or edit a value. Mutable objects in Python enable the programmers to have objects that can change their values. They generally are utilized to store a collection of data. It can be regarded as something that has mutated, and the internal state applicable within an object has changed.
