• 根据country_converter文档。
• to和src参数的有效值可以通过coco.CountryConverter().valid_class找到。

import country_converter as coco
import pandas as pd

# setupt test dataframe
df = pd.DataFrame({'code': ['AFG', 'USA', 'RU']})

# add country name by applying the convert method
df['short name'] = df.code.apply(lambda x: coco.convert(names=x, to='name_short', not_found=None))

# display(df)
  code     short name
0  AFG    Afghanistan
1  USA  United States
2   RU         Russia

# converting the column to a list and passing it to the method also works to add the short name
df['short name'] = coco.convert(names=df.code.tolist(), to='name_short', not_found=None)
