Вызовы с рабочим выходом

docker run -a stdin -a stdout -a stderr --rm --mount source=example,target=/home/pytest example_pytest  python -m mypy --ignore-missing
-imports --disallow-untyped-defs example
docker run -a stdin -a stdout -a stderr --rm --mount source=example,target=/home/pytest example_pytest python --version
