Find sum of elements in list in Python program

Python Server Side Programming Programming

In this article, we will learn about the solution to the problem statement given below.

Problem statement − We are given a list iterable, we need to compute the sum of the list

Here we will be discussing 3 approaches as discussed below

Using for loop

Example

# sum
total = 0
# creating a list
list1 = [11, 22,33,44,55,66]
# iterating over the list
for ele in range(0, len(list1)):
   total = total + list1[ele]
# printing total value
print("Sum of all elements in given list: ", total)

Output

Sum of the array is 231

Using while loop

Example

Live Demo

# Python program to find sum of elements in list
total = 0
ele = 0
# creating a list
list1 = [11,22,33,44,55,66]
# iterating using loop
while(ele < len(list1)):
   total = total + list1[ele]
   ele += 1
# printing total value
print("Sum of all elements in given list: ", total)

Output

Sum of the array is 231

Using Recursion by creating a function

Example

# list
list1 = [11,22,33,44,55,66]
# function following recursion
def sumOfList(list, size):
if (size == 0):
   return 0
else:
   return list[size - 1] + sumOfList(list, size - 1)
# main
total = sumOfList(list1, len(list1))
print("Sum of all elements in given list: ", total)

Output

Sum of the array is 231

Conclusion

In this article, we have learned how to print the sum of elements in a list.
