Mutable vs. Immutable Objects in Python

Simple put, a mutable object can be changed after it is created, and an immutable object can't. ... Objects of built-in types like (int, float, bool, str, tuple, unicode) are immutable. Objects of built-in types like (list, set, dict) are mutable.

What is the difference between mutable and immutable objects in Python?

To summarise the difference, mutable objects can change their state or contents and immutable objects can't change their state or content. Immutable Objects : These are of in-built types like int, float, bool, string, unicode, tuple. In simple words, an immutable object can't be changed after it is created.

How do you check if an object is mutable in python?

Like-wise, you might be able to "check" an object's __setattr__ method in some way to determine if it is mutable. The values, on the other hand, can be any object. If you need to check if an object is immutable, then I would use hash() .

What does mutable mean in Python?

If immutable objects are objects whose value can't change once created, a mutable object is an object whose value can change once created. Mutable objects are often objects that can store a collection of data. Lists (Python type list ) and dictionaries (Python type dict ) are examples of mutable objects.

Is list mutable or immutable in Python?

Lists and Tuples in Python

Many types in Python are immutable. Integers, floats, strings, and (as you'll learn later in this course) tuples are all immutable. Once one of these objects is created, it can't be modified, unless you reassign the object to a new value. The list is a data type that is mutable.

What is difference between mutable and immutable types?

On the other hand, Mutable objects have fields that can be changed, immutable objects have no fields that can be changed after the object is created. ...

Is set mutable or immutable?

A set is an unordered collection of items. Every set element is unique (no duplicates) and must be immutable (cannot be changed). However, a set itself is mutable.

What are mutable and immutable types in Python list both of them?

Simple put, a mutable object can be changed after it is created, and an immutable object can't. Objects of built-in types like (int, float, bool, str, tuple, unicode) are immutable. Objects of built-in types like (list, set, dict) are mutable. Custom classes are generally mutable.

Why are list called mutable types?

Unlike strings, lists are mutable. This means we can change an item in a list by accessing it directly as part of the assignment statement. Using the indexing operator (square brackets) on the left side of an assignment, we can update one of the list items.

Why are tuples immutable?

Tuples support the same sequence operations as strings. The index operator selects an element from a tuple. So like strings, tuples are immutable. Once Python has created a tuple in memory, it cannot be changed.

Are Dicts mutable Python?

Everything in Python is an object . ... Some of these objects like lists and dictionaries are mutable , meaning you can change their content without changing their identity. Other objects like integers, floats, strings and tuples are objects that can not be changed.

What are mutable types in Python?

Some of the mutable data types in Python are list, dictionary, set and user-defined classes. On the other hand, some of the immutable data types are int, float, decimal, bool, string, tuple, and range.

What is immutable data type?

Immutable data types are the objects that cannot be modified and altered (i.e. adding new elements, removing an element, replacing an element) after creating an object. The immutable data types in Python are: Tuple. Int. Float.
