Pyright does not respect a valid # type: ignore comment when a function arguments are on multiple lines.

[simon-liebehenschel]

Code example

Here is a very simplified code because I am talking not about type hints, but about how Pyright parses # ignore comments.

@limit_gen
async def my_function(*, foo, bar):
    ...

# A decorator adds a `limit` parameter, and to suppress Mypy warnings during a function call I use `# type: ignore[call-arg]`

async for _ in my_function(  # type: ignore[call-arg]
    foo=bar,
    spam=eggs,
    limit=42,
):
...

Mypy result

No errors because Mypy discovers a # type: ignore[call-arg] comment

Pyright result

A warning, unless I will copy the comment to a specific argument line:

my_function(  # type: ignore[call-arg]
    foo=bar,
    spam=eggs,
    limit=limit  # type: ignore[call-arg]
)

Question

Is this a Pyright bug or a feature?

[erictraut]

A # type: ignore comment affects only the line that it is on. This is by design.

@erictraut how would i type ignore a multi-line statement ?
here's what im trying to do

assert (  # type: ignore
            abs(1.0 - correlation) <= CUSTOM_TOLERANCES["correlation"]
        ), f"Correlation difference exceeds tolerance: {correlation}"

[erictraut]

Add the # type: ignore or # pyright: ignore to the end of the line where the error is reported. If the error is associated with a text range that spans lines, you can place it on any of the associated lines.
