Pandas - return a dataframe after groupby

Question

I have a Pandas df:

Name    No
A       1
A       2
B       2
B       2
B       3

I want to group by column Name,

Answer 1

Add parameter as_index=False to groupby:

print (df.groupby(['Name'], as_index=False)['No'].sum())
  Name  No
0    A   3
1    B   7

Or call reset_index:

print (df.groupby(['Name'])['No'].sum().reset_index())
  Name  No
0    A   3
1    B   7
