Convert list of dictionaries to dictionary of dictionaries

I have a list of dictionaries

ls1 = [{'AccountBalance': '78', 'Status': '0'},
 {'AccountBalance': '56', 'Status': '1'},
 {'AccountBalance': '34', 'Status': '0'},
 {'AccountBalance': '12', 'Status': '0'}]

I would like to convert this to a dictionary of 2 dictionaries

dict1 = {'AccountBalance': {0: '78',
  1: '56',
  2: '34',
  3:  '12'},
    'Status': {0: '0',
  1: '1',
  2: '0',
  3: '0'}}

what would be the fastest way to do this?

pd.DataFrame(ls1).to_dict() works, but I want to know if something is a little faster?

>Solution :

A one-liner solution would be

dict1 = {key: {index: item[key] for index, item in enumerate(ls1)} for key in ls1[0]}
