I need to compare more than 2 dictionaries to find out how many duplicate keys and how many times they are repeated. for example
D1 = {'a' : 'value', 'b': 'value', 'c': 'value', 'd', 'value'}
D2 = {'d', 'value', 'a' : 'value'}
D3 = {'a' : 'value', 'd', 'value', 'b': 'value'}
D4 = {'a' : 'value'}
the output shoule print repeated keys and how many times each key is repeated for example:
4-a # key 'a' is repeated 4 times accross dictionaries
2-b
3-d
