You might look at the "adpater" pattern.
It is heavily used in Zope - and there looks something like:

"I am" is two words, not one. I hope you wouldn't write "Youare"
or "Heis" :-) Whenever you write "Iam", I read it as the name "Ian", which
is very distracting.

In order to preserve your index after the aggregation, you need to make
sure it is considered a data column (via reset_index) and then choose how
your aggregation will operate on that column.

Just in case I misunderstood, why don't you make a little example of before
and after the grouping? This mailing list does not accept attachments, so
you'll have to make do with pasting a few rows of comma-separated or
tab-separated values.

Hello, Michael,
I changed groupby with one column.
The index is different.
Index([ u'AL',u'AR',u'AZ',u'CA',u'CO',u'CT',u'DC',
u'DE',u'FL',u'GA',u'IA',u'ID',u'IL',u'IN',
u'KS',u'KY',u'LA',u'MA',u'MD',u'ME',
Here's an example.
>>> import pandas as pd
>>> df = pd.DataFrame({'group': list('AB') * 2, 'data': range(4)},
index=list('wxyz'))
>>> df
data group
w 0 A
x 1 B
y 2 A
z 3 B
>>> df = df.reset_index()
>>> df
index data
Dear Michael,
To avoid complication, I only groupby using one column.
It is OK now. But, how to refer to new row index? How do I use floating index?
Float64Index([ 1.0, 4.0, 5.0, 6.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, 16.0,

To clarify that you're specifying the index as a label, use df.iloc
>>> df = pd.DataFrame({'X': range(4)}, index=list('abcd'))
>>> df
X
a 0
b 1
c 2
d 3
>>> df.loc['a']
X0
Name: a, dtype: int64

X0

What were you hoping to get from ``df[0]``?
When you say it "yields nothing" do you mean it raised an error? What was
the error message?
Have you tried a Google search for "pandas set index"?
