我基本上在pandas中有一个数据框，里面有一个国家列表，但我想按大洲和地区对每个国家进行分类。我想在原始数据框架中再添加两列。

import numpy as np
import pandas as pd
import pandasql as psql
import matplotlib.pyplot as plt
import plotly.express as px
from pandasql import sqldf
pysqldf = lambda q: sqldf(q, globals())
suicide_df = pd.read_csv(r"C:\Users\slaye\Downloads\suicide_rates\master.csv")
display(suicide_df)

字符串
现在我一直在手动编译嵌套字典，但我想知道是否有更快的方法来做到这一点。

regions = {'Asia': {'Central Asia', 'South Asia', 'East Asia', 'SouthEast Asia', 'West Asia', 'Middle East'},
          'Europe': {'Western Europe', 'Eastern Europe', 'Mediterranean', 'Nordic'},
           'North America': {'United States'}

我很抱歉，如果这是一个草率的职位，我不知道在stackoverflow格式。
