Python has the following data types built-in by default. Variable can store data of different types as per requirements.

Categories	Data Type	Example
Text	str	x = “Be Happy”
Numeric	int	x = 1
Numeric	float	x = 3.5
Numeric	complex	x = 1j
Sequence	list	x = [“A”, “B”, “C”]
Sequence	tuple	x = (“A”, “B”, “C”)
Sequence	range	x = range(6)
Mapping	dict	x = {“fruit” : “Apple”, “Price” : 200}
Set	set	x = {“A”, “B”, “C”}
Set	frozenset	x = frozenset({“A”, “B”, “C”})
Boolean	bool	x = True
Binary	bytes	x = b”Hello”
Binary	bytearray	x = bytearray(6)
Binary	memoryview	x = memoryview(bytes(6))
None	NoneType	x = None

PYTHON DATA TYPES

To get the data type of any object we can use the type() function in Python.

Example-

print (type(x))

PYTHON COLLECTIONS (ARRAYS)

There are four collection data types in the Python programming language:

List

List is a collection which is ordered and changeable. Allows duplicate members.

Tuple

Tuple is a collection which is ordered and unchangeable. Allows duplicate members.

Set

Set is a collection which is unordered, unchangeable, and unindexed. No duplicate members.

Set items are unchangeable, but you can remove and/or add items.

Dictionary

is a collection which is ordered and changeable. No duplicate members.
