how to sum all the numbers in a list in python

# to sum all the numbers we use python's sum() function
a = [4,5,89,5,33,2244,56]
a_total = sum(a)

find sum numbers in a list in python

list = [5, 8, 7, 2, 9, 13, 27]
a = 0

for i in list:
    a += i

print(a)

sum of even numbers in a list in python

>>> myList = [1, 3, 5, 6, 8, 10, 34, 2, 0, 3
>>> sum(num for num in myList if not num%2)
60

sum of number from list

int knapsackRec(int[] w, int[] v, int n, int W) {
    if (n <= 0) { 
        return 0; 
    } else if (w[n - 1] > W) {
        return knapsackRec(w, v, n - 1, W);
    } else {
        return Math.max(knapsackRec(w, v, n - 1, W), v[n - 1] 
          + knapsackRec(w, v, n - 1, W - w[n - 1]));
    }
}

sum of the number in a list in python

# 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)

Sum of list of numbers

def list_sum(num_list):
    the_sum = 0
    for i in num_list:
        the_sum = the_sum + i
    return the_sum

print(list_sum([1, 3, 5, 7, 9]))
