index = [1, 2, 3] languages = ['python', 'c', 'c++'] dictionary = dict(zip(index, languages)) print(dictionary) Run Code Output {1: 'python', 2: 'c', 3: 'c++'} We have two lists: index and languages. They are first zipped and then converted into a dictionary. The zip...
We convert dictionary keys to sets using set(dict1.keys()) and set(dict2.keys()), leveraging sets’ unordered nature and uniqueness. The difference operation (-) between sets efficiently captures keys unique to each dictionary. Finally, we print the sets containing the unique keys. ...
