Why is it important to use static typing in Python with mypy?

Using static typing in Python with mypy is important for improving code quality and preventing errors early in development.

• Early error detection — mypy checks type consistency, helping to identify mismatches and typos before running the program.
• Improving code readability and maintainability — explicit types make the code clearer for other developers and for oneself in the future.
• Integration with IDEs and tools — many editors use information from mypy for autocomplete and hints.
• Documentation — type annotations serve as additional documentation.

Example of using mypy:

from typing import List

def greet_all(names: List[str]) -> None:
    for name in names:
        print(f"Hello, {name}!")

mypy will check that a list of strings is passed to the function.

Thus, mypy helps make Python code more reliable and easier for team collaboration.
