ueshin opened a new pull request, #54352:
URL: https://github.com/apache/spark/pull/54352
### What changes were proposed in this pull request?
This is a follow-up of apache/spark#54276.
Fixes `groupby(as_index=False).apply` with dict.
### Why are the changes needed?
The case of `groupby(as_index=False).apply` with dict was missing at
apache/spark#54276.
```py
>>> psdf = ps.DataFrame(
... {"A": [1, 1, 2, 2], "B": [1, 2, 3, 4], "C": [0.362, 0.227, 1.267,
-0.562]}
... )
>>> psdf.groupby(psdf.A, as_index=False).agg({"B": "min", "C": "sum"})
A B C
0 1 1 0.589
1 2 3 0.705
>>>
>>> psdf.groupby(psdf.A + 1, as_index=False).agg({"B": "min", "C": "sum"})
B C
0 1 0.589
1 3 0.705
```
whereas pandas 3:
```py
>>> pdf = pd.DataFrame(
... {"A": [1, 1, 2, 2], "B": [1, 2, 3, 4], "C": [0.362, 0.227, 1.267,
-0.562]}
... )
>>> pdf.groupby(pdf.A, as_index=False).agg({"B": "min", "C": "sum"})
A B C
0 1 1 0.589
1 2 3 0.705
>>>
>>> pdf.groupby(pdf.A + 1, as_index=False).agg({"B": "min", "C": "sum"})
A B C
0 2 1 0.589
1 3 3 0.705
```
### Does this PR introduce _any_ user-facing change?
Yes, it will behave more like pandas 3.
