Question

write a Python program to sum all the items in a list.​

Answer 1

Answer:

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

Example #1:

Python3

# Python program to find sum of elements in list

total = 0

# creating a list

list1 = [11, 5, 17, 18, 23]

# Iterate each element in list

# and add them in variable total

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 all elements in given list: 74

Answer 2

Answer:

Following is the simplest Python program will sum all the items in a list.

arr = list(map(int,input().split()))

total  = sum(arr)

print("The sum of all the elements of the given list is:", total)

Explanation:

Let's understand the code above:

• First, we take the input of the elements of the list from the user.
• I have used the list function so that all the input elements will be arranged in the list.
• Next, we find the sum of all the elements. In Python, we have a pre-defined sum() function available that can find the sum by passing the name of the list.
• The sum of the elements is stored in the total variable.
• In the last line, we print the sum.
