CodePudding user response：

First, you must create your data. Second, you get the keys of your data. At, last, you must loop each key.

You can use the following code which is self-explainable:

import collections
info=collections.defaultdict(list,{'List of tubes': ['2324', '98', '7654'], 'List of auto:': [147, 10048, 1009, 10050, 10, 1647, 10648, 649, 1005]})
#print(info)
keys=info.keys()
for key in keys: # loop for each key
  print(f'\'{key}\': ',end='')
  tmp=info[key]
  for i,data in enumerate(tmp):
    if isinstance(data, str): # for the string type
      if i!=len(tmp)-1:
        print('\'%s\', '%(data),end='')
      else:
        print('\'%s\''%(data),end='')
    else:  # for the int type
      if i!=len(tmp)-1:
        print('%d, '%(data),end='')
      else:
        print('%d'%(data),end='')
  print()
