How can mypy ignore a single line in a source file?

Of course, the answer of this question is add # type:ignore at the end of the line that want mypy to ignore it.

When I was google for how to ignore the files for django migrations,
this question was recomment to me several times.

So I post an answer about how to ignore Django migrations:

# mypy.ini
[mypy-*.migrations.*]
ignore_errors = True

And for mypy>=0.910, pyproject.toml is supported which can be set as follows:

[tool.mypy]
python_version = 3.8
ignore_missing_imports = true

[[tool.mypy.overrides]]
module = "*.migrations.*"
ignore_errors = true

You can ignore type errors with # type: ignore as of version 0.2 (see issue #500, Ignore specific lines):

PEP 484 uses # type: ignore for ignoring type errors on particular lines ...

Also, using # type: ignore close to the top of a file [skips] checking that file altogether.

_{Source: mypy#500. See also the mypy documentation.}

Also # mypy: ignore-errors at the top of the file you want to ignore all works, if you are using shebang and coding lines should be like this:

#!/usr/bin/env python 
#-*- coding: utf-8 -*-
# mypy: ignore-errors
