I've posted this to Stack Overflow.
Why does Ctrl+I only show help for pandas DataFrames but not GroupBy objects (specifically pandas.core.groupby.generic.DataFrameGroupBy objects)?
Here is an example entered into the Spyder console:
import numpy as np
import pandas as pd
ColHead = ['A','B','C']
Data = np.random.randint(low=0,high=3,size=(12,3))
df=pd.DataFrame(Data,columns=ColHead)
gb=df.groupby('A',as_index=False)
If I place the insertion point at the end of df and press Ctrl+I, I see the documentation for the DataFrame class. If I do the same at the end of gb, the Help pane shows No documentation available. However, I can see the doc string in the source file:
c:/Users/User.Name/AppData/Local/anaconda3/envs/py39/lib/site-packages/pandas/core/groupby/generic.py

Examples
--------
>>> data = {"A": [1, 1, 2, 2],
... "B": [1, 2, 3, 4],
... "C": [0.362838, 0.227877, 1.267767, -0.562860]}
>>> df = pd.DataFrame(data)
>>> df
A B C
0 1 1 0.362838
1 1 2 0.227877
2 2 3 1.267767
3 2 4 -0.562860
The aggregation is for each column.
>>> df.groupby('A').agg('min')
B C

1 1 0.227877
2 3 -0.562860
Multiple aggregations
>>> df.groupby('A').agg(['min', 'max'])
