# Python program to find the sum of all items in a dictionary

|In this Python example, we will explore multiple ways to find the sum of all items in a dictionary.

Some of the topics which will be helpful for understanding the program implementation better are:

## 1. Using a Loop

One way to find the sum of all items in a dictionary is by using a loop. We can iterate over the values of the dictionary and add them to a variable to keep track of the sum.

my_dict = {'a': 1, 'b': 2, 'c': 3} sum_values = 0 for value in my_dict.values(): sum_values += value print("Sum of all items in the dictionary:", sum_values)

OutputSum of all items in the dictionary: 6

## 2. Using the `sum()`

Function

Another way to find the sum of all items in a dictionary is by using the `sum()`

function. We can pass the values of the dictionary to the `sum()`

function to get the sum of all items in the dictionary.

Here’s an example:

my_dict = {'a': 1, 'b': 2, 'c': 3} sum_values = sum(my_dict.values()) print("Sum of all items in the dictionary:", sum_values)

OutputSum of all items in the dictionary: 6

## 3. Using List Comprehension

We can also use list comprehension to find the sum of all items in a dictionary. We can create a list of values from the dictionary using list comprehension and then pass the list to the `sum()`

function.

This is very useful when we have to perform some operations on the value before doing the sum. For example in the program below we will multiply the number by 10 before calculating the sum.

my_dict = {'a': 1, 'b': 2, 'c': 3} sum_values = sum([value*10 for value in my_dict.values()]) print("Sum of all items in the dictionary:", sum_values)

OutputSum of all items in the dictionary: 60

## 4. Conclusion

In this article, we have discussed three different ways to find the sum of all items in a dictionary.
