df.groupby(['col1','col2']).count() My groupby returns a dataframe (shape = 5, 1) like this
col1 col2 count
1      1    10
       2     5
       3     2
2      1     4
       2     5
I would like to covert this into (5, 3) dataframe with col1 col2 being real columns.
col1 col2 count
1      1    10
1      2     5
1      3     2
2      1     4
2      2     5
I found several questions on this forum and outside. No luck.
