What are the main categories of data types in Python?

In Python, the main categories of data types can be divided into several groups:

1. Numeric types:

   • int — integers
   • float — floating-point numbers
   • complex — complex numbers

2. Sequences:

   • list — mutable list
   • tuple — immutable tuple
   • range — range of numbers

3. Strings:

   • str — sequence of characters

4. Sets:

   • set — mutable set of unique elements
   • frozenset — immutable set

5. Dictionaries:

   • dict — key-value mapping

6. Boolean values:

   • bool — True or False

7. Special types:

   • NoneType — type of None

Example of usage:

x = 10          # int
pi = 3.14       # float
name = "Anna"  # str
items = [1, 2, 3]  # list
flags = {"a", "b"}  # set
config = {"key": "value"}  # dict
is_valid = True  # bool

This covers the main data types used in Python.
