python - 如何将字典作为最后一个元素添加到字典列表中？

Question

我想将字典添加到列表中，其中包含其他几个字典。

1. 我有一个十大热门旅游城市的列表:

                City      Country  Population     Area
   
   0         Buenos Aires    Argentina     2891000     4758
   1              Toronto       Canada     2800000  2731571
   
   2          Pyeongchang  South Korea     2581000     3194
   
   3             Marakesh      Morocco      928850      200
   
   4          Albuquerque   New Mexico      559277      491
   
   5            Los Cabos       Mexico      287651     3750
   
   6           Greenville          USA       84554       68
   
   7      Archipelago Sea      Finland       60000     8300
   
   8   Walla Walla Valley          USA       32237       33
   
   9        Salina Island        Italy        4000       27
   
   10               Solta      Croatia        1700       59
   
   11        Iguazu Falls    Argentina           0      672
   

2. 我用 pandas 导入了 excel:

   import pandas as pd
   travel_df = pd.read_excel('./cities.xlsx')
   print(travel_df)
   cities = travel_df.to_dict('records')
   print(cities)
   variables = list(cities[0].keys())
   

3. 我想在列表末尾添加第 12 个元素，但不知道如何操作:

   beijing = {"City" : "Beijing", "Country" : "China", "Population" : "24000000", "Ares" : "6490" }
   print(beijing)
   

Answer 1

尝试将新行附加到您读取的 DataFrame 中。

travel_df.append(beijing, ignore_index=True)
