How to reset a DataFrame's indexes for all groups in one step?

Question

I\'ve tried to split my dataframe to groups

df = pd.DataFrame({\'A\' : [\'foo\', \'bar\', \'foo\', \'bar\',
                       \'foo\', \'bar\', \'foo\',         


        

Answer 1

Something like this would work:

for group, index in grouped.indices.iteritems():
    grouped.indices[group] = range(0, len(index))

You could probably make it less verbose if you wanted to.
