def get_3_code_country(country):
url = 'https://restcountries.eu/rest/v2/name/' + quote(country.country[0], safe='')
r = requests.get(url)

import requests
from urllib.parse import quote
data_javascript_map = sort_countries.assign(
iso_3=lambda x: get_3_code_country(x), axis = 1
)
data_javascript_map

剛拿到它，應用數據幀，applymap工程逐元素的一個數據幀的行/列的基礎上工作，並且地圖作品元素方面的一個系列 –
