Python offers several type checkers, but one of the most popular and widely used is mypy. It is a classic type checker that covers all the basic needs of a developer. Other popular solutions include pytype from Google and Pyre from Facebook. While pytype can work without type annotations, Pyre is performance-oriented Because it covers all my needs, I only use mypy.
To use mypy, simply run the following command:
mypy CODE_LOCATIONSTo enable all optional error checking flags in mypy, you can add the following configuration to your pyproject.toml file:
