What are the best practices for type checking in Python?

What are the best practices for type checking in Python?

Some best practices include using type hints, leveraging static type checkers like mypy, and keeping types consistent.

Can you explain how to use type hints in Python?

Type hints are annotations that specify the expected data types of variables, function parameters, and return values. For example, you can define a function like this: def add(a: int, b: int) -> int:.

What tools can I use for static type checking?

You can use tools like mypy, Pyright, or Pyre for static type checking in Python. They analyze your code for type consistency.

Are there any downsides to type checking?

Yes, some downsides include increased verbosity in code and potential performance overhead during type checking.
