Standard data types in Python.

In Python, there are several standard data types that can be divided into several categories:

• Numbers: int (integers), float (floating-point numbers), complex (complex numbers).
• Boolean type: bool (values True and False).
• Sequences: str (strings), list (lists), tuple (tuples).
• Sets: set (set), frozenset (immutable set).
• Dictionaries: dict (key-value mapping).
• NoneType: None — a special type to denote the absence of a value.

Example usage:

x = 10          # int
pi = 3.14       # float
name = "Alice"  # str
is_active = True  # bool
items = [1, 2, 3]  # list
config = {'host': 'localhost', 'port': 5432}  # dict
