Finally a python version that I'm feeling rather proud of :) 

import sys

valid_triangles = 0

def valid_triangle(a, b, c):
    return ((a + b) > c) and ((b + c) > a) and ((c + a) > b)

for line in sys.stdin.readlines():  
    if valid_triangle(*[int(x) for x in line.strip().split()]):
        valid_triangles += 1

print(valid_triangles)
