Python Variables: Data Types

Numeric Data Types

int: whole numbers, e.g. 1, 2, 3, etc.
float: decimal numbers, e.g. 3.14, -0.5, etc.
complex: complex numbers, e.g. 3 + 4j, 2 - 5j, etc.

Sequence Data Types

str: strings, e.g. "hello", "goodbye", etc. (can be enclosed in single quotes or double quotes)
list: ordered collections of items, e.g. [1, 2, 3], ["a", "b", "c"], etc.
tuple: ordered, immutable collections of items, e.g. (1, 2, 3), ("a", "b", "c"), etc.

Mapping Data Type

dict: unordered collections of key-value pairs, e.g. {"name": "John", "age": 30}, etc.

Set Data Types

set: unordered collections of unique items, e.g. {1, 2, 3}, {"a", "b", "c"}, etc.
frozenset: unordered, immutable collections of unique items, e.g. frozenset({1, 2, 3}), etc.

Boolean Data Type

bool: boolean values, e.g. True, False, etc.

Binary Data Type

bytes: binary data, e.g. b"hello", etc.
bytearray: mutable binary data, e.g. bytearray(b"hello"), etc.

None Data Type

None: represents the absence of a value, e.g. None, etc.
