how to calculate the sum of a list in python

# Python code to demonstrate the working of  
# sum() 
numbers = [1,2,3,4,5,1,4,5] 
  
# start parameter is not provided 
Sum = sum(numbers) 
print(Sum) # result is 25  
# start = 10 
Sum = sum(numbers, 10) 
print(Sum) # result is 10 +25 = 35

python sum of list

>>> list = [1, 2, 3]
>>> sum(list)
6

sum of list in python

a = [2, 4, 56, 7]

print(a[0] + a[1] + a[2] + a[3])
print(sum(a))

sum of elements in a list.

data = ['5', '4', '9']

sum(int(i) for i in data)
18

sum of list of lists python

List = [[1, 2, 3],
        [4, 5, 6],
        [7, 8, 9]]
          

for i in zip(*List):
  print(i)

out: 
(1, 4, 7)
(2, 5, 8)
(3, 6, 9)

sum the contents of a list python

# Sum the contents of a list without the builtin sum function

list = [1,2,3,4,5]
sum = 0

# loop through each position of the list and 
# add the contents of each position to the variable, sum
for i in range(len(list)):
	sum += list[i]

# result is 1 + 2 + 3 + 4 + 5 = 15
print(sum)

python list sum

To get the sum of a list in python, you just call the built in sum() function.
An example:

>>> lst = [3, 7, 1, 9, 4]
>>> sum(lst)
24

sum elements in list python

# Python code to demonstrate the working of 
# sum()
   
numbers = [1,2,3,4,5,1,4,5]
  
# start parameter is not provided
Sum = sum(numbers)
print(Sum)
  
# start = 10
Sum = sum(numbers, 10)
print(Sum)

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)

how to do the sum of list in python

def calculate_cards(cards):
    total= 0
    for card in cards:
        total = total + card
    return total
print(calculate_cards([11,7,5]))
