convert a json file to a python dictionnary of array

[Reims]

Hi there, i m a newbee so excuse if my question looks dummy.

so i have a json file which look like this

Output:
[{'_id': '1', 'date': '2019-09-07', 'name': 'abi', 'value': 0, 'unit': '°C'}, 
  {'_id': '2', 'date': '2019-09-08', 'name': 'allo', 'value': 3, 'unit': '°F'},
  {'_id': '3', 'date': '2019-09-09', 'name': 'ali', 'value': 0, 'unit': '°C'}]

and i want to read this json file in order to convert it into a dictionnary of array which looks like

Output:
[{'_id': [ '1', '2','3']},
 {'date': [ '2019-09-07', '2019-09-08','2019-09-09']},
 {'name': [ 'abi', 'allo','ali']},
 {'value': [ '0', '3','0']},
 {'unit': [ '°C', '°F','°C']},]

Thank you in advance
