In this assignment you will read through and parse a file with text and numbers. You will extract all the numbers in the file and compute the sum of the numbers.

import re
f = open("1234.txt")
x = list()
for l in f:
    l = l.rstrip()
    a = re.findall('[0-9]+',l)
    for b in a:
        c = int(b)
        x.append(c)
print(sum(x))
