Explain the concept of typing in Python and its features.

Python uses dynamic and strong typing. This means that the variable's type is determined at runtime, not beforehand, and the language strictly enforces data types, preventing, for example, implicit addition of a string and a number.

Features of typing in Python:

• Dynamic typing: a variable can reference objects of different types at different times.
• Strong typing: operations between incompatible types cause errors.
• Support for type annotations: starting from Python 3.5, you can specify variable and function types for static analysis, but this does not affect code execution.

Example of type annotation:

def greet(name: str) -> str:
    return f"Hello, {name}!"

message: str = greet("Alice")

Thus, Python combines the flexibility of dynamic typing with the ability to use types to improve readability and support analysis tools.
