split a Pandas series without a multiindex

Question

I would like to take a Pandas Series with a single-level index and split on that index into a dataframe with multiple columns. For instance, for input:

s = p         


        

Answer 1

You can use groupby, apply, reset_index to create a multiindex Series, and then call unstack:

import pandas as pd
s = pd.Series(range(10,17), index=['a','a','b','b','c','c','c'])
df = s.groupby(level=0).apply(pd.Series.reset_index, drop=True).unstack(0)
print df

output:

   a   b   c
0  10  12  14
1  11  13  15
2 NaN NaN  16
