Nested dictionaries in Python are a powerful data structure that allows you to store and access data in a hierarchical manner. In this article, we will explore nested dictionaries in detail and provide examples to help you understand how to use them effectively in your Python code. Understanding...
A Python nested dictionary is a dictionary within a dictionary, where the outer dictionary’s values are also dictionaries. The following code shows an elementary example. d1={0:{"Dept":"Mathematics","Prof":"Dr Jack"},1:{"Dept":"Physics","Prof":"Dr Mark"},}print(d1) ...
The problem at hand is to find the summation of values present in the nested dictionary and we have to implement the code using Python. So the nested dictionaries are the dictionary inside the dictionary. And we have to find the nested values and sum them up as a result.Sum for all the...
