對(duì)于每行重復(fù)，請(qǐng)使用：df = pd.DataFrame(data = {'Name':['Tom', 'Jerry', 'Jack', 'Terry'],

'OtherName':['Tom', 'John', 'Bob','Steve'],

'Age':[20, 21, 19, 18]})

print (df)

import inflect

p = inflect.engine()

#map by function for dynamic counter

f = lambda i: p.number_to_words(p.ordinal(i))

#columns filled by names

cols = ['Name','OtherName']

#reshaped to MultiIndex Series

s = df[cols].stack()

#counter per groups

count = s.groupby([s.index.get_level_values(0),s]).cumcount().add(1)

#mask for filter duplicates

動(dòng)態(tài)字典應(yīng)類(lèi)似于：import inflect

mask = df.Name.duplicated(keep=False)

f = lambda i: p.number_to_words(p.ordinal(i))

df.loc[mask, 'Name'] = df[mask].groupby('Name').cumcount().add(1).map(f) + df.loc[mask, 'Name']

print (df)
