Installing and running mypy This command makes mypy type check your program.py file and print out any errors it finds. Mypy will type check your code statically: this means that it will check for errors without ever running your code, just like a linter.

If all of your Python files live within a specific module or directory, then just running mypy folder_name is fine.

You can also pass in multiple paths if you prefer to target specific files or modules. For example: mypy a.py b.py some_directory.

The documentation has some more details and caveats.
