How to save split data in panda in reverse order?

Question

You can use this to create the dataframe:

xyz = pd.DataFrame({\'release\' : [\'7 June 2013\', \'2012\', \'31 January 2013\',
                                 \'F         


        

Answer 1

Try reversing the result.

dataframe[['year','month','day']] = dataframe['release'].str.rsplit(expand=True).reverse()

Answer 2

You could

In [17]: dataframe[['year', 'month', 'day']] = dataframe['release'].apply(
                                                    lambda x: pd.Series(x.split()[::-1]))
In [18]: dataframe
Out[18]:
           release  year     month  day
0      7 June 2013  2013      June    7
1             2012  2012       NaN  NaN
2  31 January 2013  2013   January   31
3    February 2008  2008  February  NaN
4     17 June 2014  2014      June   17
5             2013  2013       NaN  NaN
