Can you name the main categories of data types used in programming languages?

The main categories of data types in programming languages include:

• Numeric types: integers (int), floating-point numbers (float, double).
• Boolean types: boolean values (bool) — true or false.
• Character and string types: characters (char), strings (string).
• Collections: arrays, lists, sets, dictionaries (hash tables).
• User-defined types: structures, classes, enumerations.
• Special types: null/None (absence of value), pointers (in some languages).

For example, in Python, there are int, float, bool, str, list, dict, set, etc.
