python sum of list

1# Python code to demonstrate the working of  
2# sum() 
3numbers = [1,2,3,4,5,1,4,5] 
4  
5# start parameter is not provided 
6Sum = sum(numbers) 
7print(Sum) # result is 25  
8# start = 10 
9Sum = sum(numbers, 10) 
10print(Sum) # result is 10 +25 = 35

1>>> list = [1, 2, 3]
2>>> sum(list)
36

1# Sum the contents of a list without the builtin sum function
2
3list = [1,2,3,4,5]
4sum = 0
5
6# loop through each position of the list and 
7# add the contents of each position to the variable, sum
8for i in range(len(list)):
9	sum += list[i]
10
11# result is 1 + 2 + 3 + 4 + 5 = 15
12print(sum)

1To get the sum of a list in python, you just call the built in sum() function.
2An example:
3
4>>> lst = [3, 7, 1, 9, 4]
5>>> sum(lst)
624

1b = [1,2,3]
2a = sum(b)
3# 6

3    for card in cards:
4        total = total + card
5    return total
