Every variable in Python holds an instance of an Object. There are two types of objects in python i.e. Mutable and Immutable objects. The difference, mutable objects can change their state or contents and immutable objects can’t change their state or content.
Every variable in python holds an instance of an object. There are two types of objects in python i.e. Mutable and Immutable objects. Whenever an object is instantiated, it is assigned a unique object id. The type of the object is defined at the runtime and it can’t be changed afterwards. However, it’s state can be changed if it is a mutable object.
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.
## Python code to test that ## tuples are immutable tuple1 = (0, 1, 2, 3) tuple1 = 4 print(tuple1)
Traceback (most recent call last): File "e0eaddff843a8695575daec34506f126.py", line 3, in tuple1=4 TypeError: 'tuple' object does not support item assignment
## Python code to test that ## strings are immutable message = "Welcome to GeeksforGeeks" message = 'p' print(message)
Traceback (most recent call last): File "/home/ff856d3c5411909530c4d328eeca165b.py", line 3, in message = 'p' TypeError: 'str' object does not support item assignment
Mutable Objects : These are of type list, dict, set . Custom classes are generally mutable.
## Python code to test that ## lists are mutable color = ["red", "blue", "green"] print(color) color = "pink" color[-1] = "orange" print(color)
['red', 'blue', 'green'] ['pink', 'blue', 'orange']
tup = ([3, 4, 5], 'myname')
The tuple consists of a string and a list. Strings are immutable so we can’t change its value. But the contents of the list can change. The tuple itself isn’t mutable but contain items that are mutable.
