Ref: Python-pycountry | Understand How to Use pycountry
These two python libraries are both used to process information about country names. For the library of country-converter, it can be used to convert the dirty data (country names with different writting types) to the nomalized type.
Example:
import country_converter as coco
some_names = ['United Rep. of Tanzania', 'DE', 'Cape Verde', '788', 'Burma', 'COG',
'Iran (Islamic Republic of)', 'Korea, Republic of',
"Dem. People's Rep. of Korea"]
standard_names = coco.convert(names=some_names, to='name_short')
print(standard_names)
