`lstComplete = []
fichNbr = open("nombres.txt", "r")
lstComplete = fichNbr
somme = 0

for i in lstComplete:
    i = i.split()`

Answer 1

Turn them into a list and sum them:

with open('nombres.txt', 'r') as f:
    num_list = f.read().split()
    print sum([int(n) for n in num_list])

Returns 3227

Answer 2

Open the file and use read() method to get the content and then convert string to int, use sum() to get the result:

>>> sum(map(int,open('nombres.txt').read().split()))
3227
