Keys: states names are keys (punjab, haryana, himachal, up)

Values: Each key has values assigned to it in this case chandigarh,shimla,lukhnow are the values.

Any values associated with key can be checked by typing dictionary [Key].The keys and values are also checked by its function keys l.keys and values l.values as shown in image above.
