type: ignore doesn't work with multi-line statements

[sharmaeklavya2]

file.py:

1 \
+ '2'  # type: ignore

gives output

file.py:1: error: Unsupported operand types for + ("int" and "str")

which is wrong IMO.

#type: ignore must be placed on the same line as the error. You won't be able to do that with backslash multi line statements, but those aren't considered good style anyway. If you need a type ignore on a multi line statement, use parens and place the type ignore on the line with the error.

Unfortunately the suggested workaround doesn't work for

from x import long, list, of, symbols, ... \
    wrapping, around, and, further, ... \
    ...

(e.g.

from flask_login import LoginManager, login_required, login_user, \
    logout_user, UserMixin, current_user  # type: ignore

)

Any ideas?

You can put parentheses around your long list of imports instead of using backslashes.

As I wrote, I can't make it work:

from module_mypy_doesnt_know import ( a, b,
    c, d,
    e, f )  # type: ignore

test.py:1: error: Cannot find implementation or library stub for module named 'module_mypy_doesnt_know'
test.py:1: note: See https://mypy.readthedocs.io/en/latest/running_mypy.html#missing-imports
Found 1 error in 1 file (checked 1 source file)

Try

from module_mypy_doesnt_know import ( a, b,  # type: ignore
    c, d,
    e, f )

The type ignore has to be on the physical line where the error is reported.

Seems to work, thanks. Though I find it really nasty - any good reason to have it like that (except for "wasn't yet implemented, because python parsing is too rigidly line oriented")?
