Get sum of values of a Dictionary in Python

This tutorial will discuss how to get sum of values of a dictionary in Python.

To get the sum of all values in a dictionary, we can call the values() method of the dictionary. It returns an iterable sequence of all the values from the dictionary and then we can pass those values into the sum() function. It will return the sum of all the values from the dictionary.

For instance, we have a dictionary that contains student data like names and ages. Like this,

student_data = {
    "Varun Sharma": 21,
    "Renuka Singh": 19,
    "Sachin Roy": 20}

Now, if we want to get the total age, we can retrieve all values from the dictionary using the values() method, then pass them into the sum function, which will return the total age. Like this,

total_age = sum(student_data.values())

It will add all the values of Dictionary into single numeric value.

Let’s see the complete example,

# Student data dictionary with names
# as keys and ages as values
student_data = {
    "Varun Sharma": 21,
    "Renuka Singh": 19,
    "Sachin Roy": 20}

# Calculate the sum of ages
total_age = sum(student_data.values())

# Print the sum of ages
print("Sum of ages:", total_age)

Output

Sum of ages: 60
