Mutable and Immutable

Mutable object : An object whose internal state can be changed is mutable.
Immutable object: Immutable doesn't allow any change in the object once it has been created.

Let's check mutability of List and tuple

L1=["c","o","d","e","n","g"]
L1[3]="i"
print(L1)

Output: ["c","o","d","i","n","g"]
👉 List is mutable

T1=("c","o","d","e","n","g")
T1(3)="i"
print(T1)

⭕️ TypeError: 'tuple' object does not support item assignment
👉 Tuple is immutable

Did you get what is really mean by the word "mutable" and "immutable"?
