Python program to find sum of elements in list
Given a list of numbers, write a Python program to find the sum of all the elements in the list.
Example:
Input: [12, 15, 3, 10] Output: 40 Input: [17, 5, 3, 5] Output: 30

Python3
# Python program to find sum of elements in listtotal = 0# creating a listlist1 = [11, 5, 17, 18, 23]# Iterate each element in list# and add them in variable totalfor ele in range(0, len(list1)): total = total + list1[ele]# printing total valueprint("Sum of all elements in given list: ", total) |
Output:
Sum of all elements in given list: 74
Example #2 : Using while() loop
Python3
# Python program to find sum of elements in listtotal = 0ele = 0# creating a listlist1 = [11, 5, 17, 18, 23]# Iterate each element in list# and add them in variable totalwhile(ele < len(list1)): total = total + list1[ele] ele += 1 # printing total valueprint("Sum of all elements in given list: ", total) |
Output:
Sum of all elements in given list: 74
Example #3: Recursive way
Python3
# Python program to find sum of all# elements in list using recursion# creating a listlist1 = [11, 5, 17, 18, 23]# creating sum_list functiondef sumOfList(list, size): if (size == 0): return 0 else: return list[size - 1] + sumOfList(list, size - 1) # Driver code total = sumOfList(list1, len(list1))print("Sum of all elements in given list: ", total) |
Output:
Sum of all elements in given list: 74
Example #4: Using sum() method
Python3
# Python program to find sum of elements in list# creating a listlist1 = [11, 5, 17, 18, 23]# using sum() functiontotal = sum(list1)# printing total valueprint("Sum of all elements in given list: ", total) |
Output:
Sum of all elements in given list: 74
