Now I want to create another dict with like this

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


Would you please help me how I can do this? and if this is not the right
place to ask this question then please help me where I can ask this? I had
tried stackoverflow but that not worked.

items isn't a dictionary; as MRAB mentioned, it's a list of 
dictionaries. Each dictionary in items looks like a database record with 
fields (client, name, rating, and total).

When you say you want to replace duplicate client fields by "", it 
almost looks like you're getting ready to print a report that looks 
something like this:

xyz    Ilir Meta                              0.06    100
          Abdelmadjid Tebboune    4.00    100
          Alexander Lukashenko     3.10
...

where the report will look better when duplicate client values aren't 
printed.

If that's the case, there are almost certainly better ways to do it. 
Changing values in items might have unforeseen consequences, since once 
duplicate client fields have been wiped out, there's no way to retrieve 
items[1]["client"] without looking at items[0]. And if the list of items 
is ever reordered, some of the client fields will be lost for good.

I hope this helps.
