# pandas.Series.cat

`Series.``cat`()

  Accessor object for categorical properties of the Series values.

  Be aware that assigning to categories is a inplace operation, while all methods return new categorical data per default (but can be called with inplace=True).

  Examples

      >>> s.cat.categories
      >>> s.cat.categories = list('abc')
      >>> s.cat.rename_categories(list('cab'))
      >>> s.cat.reorder_categories(list('cab'))
      >>> s.cat.add_categories(['d','e'])
      >>> s.cat.remove_categories(['d'])
      >>> s.cat.remove_unused_categories()
      >>> s.cat.set_categories(list('abcde'))
      >>> s.cat.as_ordered()
      >>> s.cat.as_unordered()
