Pandas - Return A Dataframe After Groupby

I have a Pandas df: Name No A 1 A 2 B 2 B 2 B 3 I want to group by column Name, sum column No and then return a 2-column dataframe like this: Name

Solution 1:

Add parameter as_index=False to groupby:

print (df.groupby(['Name'], as_index=False)['No'].sum())
  Name  No
0    A   31    B   7

Or call reset_index:

print (df.groupby(['Name'])['No'].sum().reset_index())
  Name  No
0A31B7
