将 Pandas 数据帧转换为特定的 JSON 结构

Question

我有兴趣从 Pandas Dataframes 中获取我无法从任何地方获得的特定 json 结构。

代码

html = requests.get(url).content
df_list = pd.read_html(html)
df = df_list[-1]
print(df)
#print(df.to_json())

输出

  Howe center       1st & river        4th & river  
5    8:37 AM            8:50 AM            8:52 AM        
6    8:57 AM            9:10 AM            9:12 AM         
7    9:17 AM            9:30 AM            9:32 AM         

所需的 JSON

{
 "Howe Center":["8:37 AM", "8:57 AM", "9:17 AM"],
 "1st & river":["8:50 AM", "9:10 AM", "9:30 AM"],
 "4th & river":["8:52 AM", "9:12 AM", "9:32 AM"]
}

我得到了什么

{
 "Howe Center":{"0":"8:37 AM,"1":"8:57 AM",...},
 "1st & river":{"0":"8:50 AM, ...}

感谢任何帮助！谢谢

用途：

#import json
my_json=json.dumps(df.to_dict('list'))
print(my_json)

{"How ecenter": ["8:37 AM", "8:57 AM", "9:17 AM"], "1st & river": ["8:50 AM", "9:10 AM", "9:30 AM"], "4t & river": ["8:52 AM", "9:12 AM", "9:32 AM"]}
