Python dictionaries don't allow items with the same key ie duplicate items, so if we have an item with the same key (country) with different values in both dictionaries, the dictionary gets updated with the later key-value pair. Merge two or more dictionaries with ** operator This is one...
Write a Python script to merge two Python dictionaries. Sample Solution-1: Python Code: # Create the first dictionary 'd1' with key-value pairs. d1 = {'a': 100, 'b': 200} # Create the second dictionary 'd2' with key-value pairs. d2 = {'x': 300, 'y': 200} # Create a ...

keys())[0]) str💡 Explanation:Both the object s and the string "s" hash to the same value because SomeClass inherits the __hash__ method of str class. SomeClass("s") == "s" evaluates to True because SomeClass also inherits __eq__ method from str class. Since both the objects...
