提取鍵值對並轉置嵌套字典

Question

從這個下面的數據

people = {1: {'name': 'John', 'age': '27', 'sex': 'Male'},
          2: {'name': 'Marie', 'age': '22', 'sex': 'Female'},
          3: {'name': 'Luna', 'age': '24', 'sex': 'Female'},
          4: {'name': 'Peter', 'age': '29', 'sex': 'Male'}}

1. 如何提取所有名稱：例如：['John','Marie','Luna','Peter']

2. 我如何轉置這個 dict 並得到如下所示的內容

   new_dict = {name: {'John','Marie','Luna','Peter'}，年齡：{'27','22','24','29'}，性別：{'Male', '女','女','男'}}

Answer 1

從你的dict創建一個dataframe ，如：

import pandas as pd

df = pd.DataFrame.from_dict(people)

轉置dataframe

df2 = df.T

將dataframe轉換為dict

df2.to_dict
