Can you explain what data types are and what role they play in Python?

Data types in Python are categories of values that determine what operations can be performed with these values and how they are stored in memory. They play a key role as they allow the interpreter to understand how to process data.

In Python, there are several main data types:

• Numbers (int, float, complex)
• Strings (str)
• Boolean values (bool)
• Lists (list)
• Tuples (tuple)
• Sets (set)
• Dictionaries (dict)

For example:

x = 10       # int
name = "Ivan"  # str
is_active = True # bool

Python is a dynamically typed language, so the variable type is determined automatically at runtime, but understanding types helps to write correct and efficient code.
