What types of data structures support modification of their elements, and which do not?

In Python, data structures are divided into mutable and immutable.

Mutable data structures:

• list
• dict
• set

Immutable data structures:

• tuple
• str
• frozenset

For example, a list can be modified by adding or removing elements:

my_list = [1, 2, 3]
my_list.append(4)  # Now my_list = [1, 2, 3, 4]

But a tuple cannot be changed after creation:

my_tuple = (1, 2, 3)
# my_tuple[0] = 10  # This will raise a TypeError
