Write a Python program to combine two or more dictionaries, creating a list of values for each key. Create a new collections.defaultdict with list as the default value for each key and loop over dicts. Use dict.append() to map the values of the dictionary to keys. Use dict() to ...

allowing you to combine multiple dictionaries into a single dictionary. It allows you to iterate over the dictionaries and add the key-value pairs to a new dictionary in a loop.
From Python version 3.9 onward, we can use the merge operators (represented by|) to combine two dictionaries: >>>x = a | b>>>print(x) {1:'fish',2:'chips',3:'jelly',4:'time'} The dictionary merge operators can also be used in the place of nested dictionaries too. Here, the ...
