[Bug]: No overload variant of "__getitem__" of "Spines" matches argument type "slice" [call-overload] #26808
Description
Bug summary
Following the docs on Spines, specifically this pattern:
spines[:].set_visible(False)leads to a mypy error:
error: No overload variant of "__getitem__" of "Spines" matches argument type "slice" [call-overload]
note: Possible overload variants:
note: def __getitem__(self, str, /) -> Spine
note: def __getitem__(self, list[str], /) -> SpinesProxy
Code for reproduction
import matplotlib.pyplot as plt
ax = plt.gca()
ax.spines[:].set_visible(False)Actual outcome
error: No overload variant of "__getitem__" of "Spines" matches argument type "slice" [call-overload]
note: Possible overload variants:
note: def __getitem__(self, str, /) -> Spine
note: def __getitem__(self, list[str], /) -> SpinesProxy
Expected outcome
mypy passes the above code as correctly typed.
Fix would likely be to define an overload for a slice type here:
matplotlib/lib/matplotlib/spines.pyi
Line 69 in 258dd85
