I'm very curious about the end goal in your question.  Are you sure you
want to remove the client value?  Will that break a relationship between
items?  This looks to me like what you actually want is a dictionary of
clients/names:

clients = {
        'xyz': [
            {'name': "Ilir Meta", 'rating': 0.06, 'total': 100},
            {'name': "Abdelmadjid Tebboune", 'rating': 4.0, 'total': ''},
            {'name': "Alexander Lukashenko", 'rating': 3.1, 'total': ''},
            {'name': "Miguel Díaz-Canel", 'rating': 0.32, 'total': ''},
        ],
        'udz': [ 
            {'name': "Ilir Meta", 'rating': 0.06, 'total': 150},
            {'name': "Abdelmadjid Tebboune", 'rating': 4.0, 'total': ''},
            {'name': "Alexander Lukashenko", 'rating': 3.1, 'total': ''},
            {'name': "Miguel Díaz-Canel", 'rating': 0.32, 'total': ''}
        ]
}

so rather than loop through and remove information, just add items to
the appropriate client list?
