is fixed (GH3602) – Allow insert/delete to non-unique columns (GH3679) – Non-unique indexing with a slice via loc and friends fixed (GH3659) – Allow insert/delete to non-unique columns (GH3679) – Extend calling object. E.g. code written like df = df.fillna(0, inplace=True) may stop working. To fix, simply delete the unnecessary variable assignment. • pandas.merge no longer sorts the group keys (sort=False) default not included in computations. See the Missing Data section Reindexing allows you to change/add/delete the index on a specified axis. This returns a copy of the data. In [52]: df1 = df.reindex(index=dates[0:4]
