Characteristics of Mutable data types in Python
There are some characteristics of mutable data types in Python:
• Changeable: Their values can be modified after creation.
• Add, Update, Delete Elements: You can add new items, remove existing ones or update values.

• Examples: Set.
• Indexing and Slicing: Ordered mutable types like lists allow access and modification using indexes.
• Dynamic Size: The number of elements can grow or shrink over time.

12.8.2 Immutable Data Types
An immutable object in Python is an object whose value cannot be changed after it is created. Once you assign a value
to it, you cannot modify the same object. If you try to change it, Python creates a new object instead of modifying the
original one. Immutable objects can also be heterogeneous, which means they can store elements of different data
types, such as numbers, strings and Boolean values (for example, a tuple).

# Assigning an integer value to variable x
x = 100
# Printing the original value of x
print("Original value of x:", x)
# Reassigning a new integer value to x
x = 200
# Printing the new value of x
print("New value of x:", x)
