Can you name the main data types used in Python?

Python has several basic data types:

• int — integers, e.g., 1, 42, -7
• float — floating-point numbers, e.g., 3.14, -0.001
• str — strings, e.g., "Hello", 'Python'
• bool — boolean values: True and False
• list — mutable sequences, e.g., [1, 2, 3]
• tuple — immutable sequences, e.g., (1, 2, 3)
• dict — dictionaries (associative arrays), e.g., {"key": "value"}
• set — sets, e.g., {1, 2, 3}

There are also special types like NoneType (value None) and user-defined classes.
