pandas - 创建 Pandas 系列列表但不知道如何访问索引值？

Question

我正在尝试使用具有 0、1、2、3... 的系列创建数据框，并具有相应的值“Qatar”、“USA”等。这是代码:

import pandas as pd
import numpy as np

dict_country_fifa = pd.Series([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32],index=["Qatar","Ecuador","Senegal","Netherlands","Argentina","Saudi Arabia","Mexico","Poland","Spain","Costa Rica","Germany","Japan","Brazil","Serbia","Switzerland","Cameroon","England","Iran","USA","Wales","France","Australia","Denmark","Tunisia","Belgium","Canada","Morroco","Croatia","Portugal","Ghana","Uruguay","South Korea"])
print(dict_country_fifa[1])

所以如果我 print(dict_country_fifa[1])我得到的输出是 >>> 2 # 这是列表中 Dataframe 中的 1,2 <--- 2 值但我的问题是如何打印卡塔尔或厄瓜多尔等索引值？？

我试着跟随

print(dict_country_fifa.get(3))
output is >>> 4

但我希望返回国家名称？我如何获得名称而不是 4 ？

Answer 1

您已将国家名称设置为系列的索引。
因此，您需要从索引中检索名称，如下所示。

print(dict_country_fifa.index[3])

输出:

Netherlands
