Using Python to Calculate Sum of List of Numbers

To calculate the sum of a list of numbers in Python, the easiest way is with the sum() function.

l = [1,2,3,4,5,6,7]

print(sum(l))

#Output:
28

You can also use a for loop to sum the numbers of a list.

l = [1,2,3,4,5,6,7]

s = 0

for num in l:
    s = s + num

print(s)

#Output:
28

When working with collections of data in Python, the ability to summarize the data easily is valuable.

One such case is if you want to get the sum of a list of numbers.

To calculate the sum of a list of numbers in Python, the easiest way is with the sum() function.

sum() returns the sum of a list of numbers.

Below shows you how to get the sum of a list of numbers in Python with sum().

l = [1,2,3,4,5,6,7]

print(sum(l))

#Output:
28

Using For Loop to Get Sum of List in Python

Another way you can add numbers of a list together is with a for loop.

To add the numbers of a list up, initialize a variable which will keep the running sum and then add each element to the running sum.

Below shows you how to get the sum of a list of numbers in Python with a for loop.

l = [1,2,3,4,5,6,7]

s = 0

for num in l:
    s = s + num

print(s)

#Output:
28
