आप पुनःक्रमित क्यों करेंगे?

dogs['coat'] = dogs["coat"].cat.reorder_categories(
  new_categories = ['short', 'medium', 'wirehaired', 'long'],

  ordered=True
)

inplace का उपयोग:

dogs["coat"].cat.reorder_categories(
  new_categories = ['short', 'medium', 'wirehaired', 'long'],
  ordered=True,

  inplace=True
)

dogs['coat'] = dogs["coat"].cat.reorder_categories(
  new_categories = ['short', 'medium', 'wirehaired', 'long'],
  ordered=True
)

dogs.groupby(by=['coat'])['age'].mean()

coat
short         8.364746
medium        9.027982
wirehaired    8.424136
long          9.552056

dogs['coat'] = dogs["coat"].cat.reorder_categories(
  new_categories = ['short', 'medium', 'long', 'wirehaired'],

  ordered=False
)

dogs.groupby(by=['coat'])['age'].mean()

coat
short         8.364746
medium        9.027982
long          9.552056
wirehaired    8.424136
