I’m using Odoo and I would like to make a comparison between two dictionaries without using any library. This comparison should return a dictionary with the differences. So here are my two dictionaries :

list1 = {
    'Office Furniture':
    [
        {
            'name': 'Office chairs can harm your floor: protect it.',
            'qty': 3
        },
    ]
}


list2 = {
    'Office Furniture': 
    [
        {
            'name': 'Office chairs can harm your floor: protect it.', 
            'qty': 3
        }, 
        {
            'name': '160x80cm, with large legs.', 
            'qty': 1
        }
    ], 
    'Services': 
    [
        {
            'name': 'designing', 
            'qty': 1
        }
    ]
}

I would like, without any library, to got the differences between those two dictionaries like this:

differences = {
   'Office Furniture':
   [
       {
           'name': '160x80cm, with large legs.',
           'qty': 1
       }
   ],

   'Services':
   [
       {
           'name': 'designing',
           'qty': 1
       }
   ]
}

Thanks a lot for your help !
