What are the differences between MyPy and other type checkers?

MyPy is a static type checker for Python, but there are others like Pyright and Pyre. MyPy focuses on gradual typing, while Pyright is known for its speed and performance. Would you like to know more about a specific type checker?

Can you explain how MyPy's gradual typing works?

Sure! MyPy allows you to add type hints to your Python code gradually. You can start with a few type annotations and progressively add more as needed, which helps in maintaining flexibility while improving code quality.

How does Pyright compare to MyPy in terms of performance?

Pyright is generally faster than MyPy, especially for large codebases. It uses a different architecture that allows for quicker type checking, making it a popular choice for developers who prioritize speed.

Are there any specific use cases where one is preferred over the other?

Yes, MyPy is often preferred in projects that require gradual typing and integration with existing codebases, while Pyright is favored in environments where performance is critical, such as large-scale applications.
