Python program to find the sum of all items in a dictionary
In this article, we will learn about the solution to the problem statement given below.
Problem statement − We are given a dictionary, and we need to print the 3 highest value in a dictionary.
Three approaches to the problem statement are given below:
Approach 1 − Calculating sum from the dictionary iterable
Example
# sum function def Sum(myDict): sum_ = 0 for i in myDict: sum_ = sum_ + myDict[i] return sum_ # Driver Function dict = {'T': 1, 'U':2, 'T':3, 'O':4, 'R':5} print("Sum of dictionary values :", Sum(dict))
Output
Sum of dictionary values : 14
Approach 2 − Calculating the sum from the dictionary.values() iterable
Example
# sum function def Sum(dict): sum_ = 0 for i in dict.values(): sum_ = sum_ + i return sum_ # Driver Function dict = {'T': 1, 'U':2, 'T':3, 'O':4, 'R':5} print("Sum of dictionary values :", Sum(dict))
Output
Sum of dictionary values : 14
Approach 3 − Calculating the sum from the dictionary.values() iterable
Example
# sum function def Sum(dict): sum_ = 0 for i in dict.keys(): sum_ = sum_ + dict[i] return sum_ # Driver Function dict = {'T': 1, 'U':2, 'T':3, 'O':4, 'R':5} print("Sum of dictionary values :", Sum(dict))
Output
Sum of dictionary values : 14
Conclusion
In this article, we have learned how we can find the highest 3 values in a dictionary
