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. 我列出了十个热门旅游城市：

     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. 我用熊猫导入了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. 我想在列表的末尾添加第12个元素，但不知道如何做：

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

Answer 1

尝试将新行追加到读取的DataFrame中。

travel_df.append(beijing, ignore_index=True)
