Unsupported operand types for > ("Series[Any]" and "Timedelta")

[acjh]

pandas supports comparison for Series[Timedelta] and Timedelta, but pandas-stubs does not.

import pandas as pd

s = pd.Series([pd.Timedelta(minutes=2)])
result = s > pd.Timedelta(hours=1)

Using mypy:

$ mypy tests.py
tests.py:4: error: Unsupported operand types for > ("Series[Any]" and "Timedelta")

Version of installed pandas-stubs: 1.4.3.220724

Note: This is similar to #27, which reported for Timestamp.

Proposed solution

Accept Scalar, which is a superset of {Timestamp}:

 def __gt__(
-    self, other: num | _ListLike | Series[S1] | Timestamp
+    self, other: num | _ListLike | Series[S1] | Scalar
 ) -> Series[_bool]: ...

Supporting info

pandas.Series.gt is documented as:

Equivalent to series > other, but with support to substitute a fill_value for missing data in either one of the inputs.

And gt is already type hinted with Scalar in pandas-stubs:

 def gt(
    self,
    other: Scalar | Series[S1],
    ...
