If the given list has a number then use the sum() function to sum all the items in a list. You can write your own Python program to sum all the items in a list using a while loop or for loop with a + operator.
Python program to sum all the items in a list
Simple example code to add all the numbers using python’s sum() function
a = [4, 5, 89, 5, 33, 2244, 56] a_total = sum(a) print("Sum:", a_total)
Using for loop
items = [4, 5, 89, 5, 33, 2244, 56] sum_numbers = 0 for x in items: sum_numbers += x print(sum_numbers)
Using while() loop
items = [4, 5, 89, 5, 56] total = 0 ele = 0 while ele < len(items): total = total + items[ele] ele += 1 print(total)
