FutureWarning when using "color" argument in plotly express with pandas 2.2.0

[BlastoiseBlue]

Pandas looks like it will be changing the semantics of the get_group() method in a future version, specifically for groupings created using a length-1 list-like. The current behavior of it accepting a single value in get_group() is deprecated, and will require using a tuple in the future. (This only applies to groupings created with a length-1 list (groupby(["a"]),) groupings created with a single value (groupby("a")) are unaffected.)

import plotly.express as px

px.scatter(x=[1, 2, 3], y=[10, 20, 30], color=["a", "b", "a"])

/opt/conda/lib/python3.11/site-packages/plotly/express/_core.py:2065: FutureWarning: When grouping with a length-1 list-like, you will need to pass a length-1 tuple to get_group in a future version of pandas. Pass `(name,)` instead of `name` to silence this warning.

Is there a way to surpress this warning ?

I am seeing the same thing, is there any fixes? Thanks!

The behavior that causes the warning is fixed in v5.19.0, but if you're using an older version, then I believe this should silence the warning:

import warnings

warnings.filterwarnings(
    action="ignore",
    message=r"When grouping with a length-1 list-like, you will need to pass a length-1 tuple to get_group in a future version of pandas\. Pass `\(name,\)` instead of `name` to silence this warning\.",
    category=FutureWarning,
    module=r"plotly\.express\._core",
)

Thank you @BlastoiseBlue for the solution to silence the warning for previous versions.

For now, since Plotly v5.19.0 fixes the issue, I'm going to close it.
