Python has various datatypes including int, float, str, list, tuple, dict, set, bool.

• int: whole numbers (e.g. 5)

• float: decimal numbers (e.g. 3.14)

• str: text (e.g. 'hello')

• list: ordered collection (e.g. [1, 2, 3])

• tuple: ordered, immutable collection (e.g. (1, 2, 3))

• dict: key-value pairs (e.g. {'key': 'value'})

• set: unordered collection of unique elements (e.g. {1, 2, 3})

• bool: True or False values

A set is a collection of unique elements with no specific order, while a frozen set is an immutable set that cannot be changed.

• A set does not allow duplicate elements

• A frozen set is created using the frozenset() function

• Sets are mutable and can be modified, while frozen sets are immutable

• Example: set1 = {1, 2, 3} ; frozenset1 = frozenset(set1)
