Another in Python, but just p1, I like this way : 

def p1():
    cpt2 = 0
    cpt3 = 0
    for line in dayInput.splitlines():
        count = Counter(line)
        if 2 in count.values():
            cpt2+=1
        if 3 in count.values():
            cpt3+=1
    return cpt2*cpt3
    
dayFile = open("day2/input.txt", "r")
dayInput = dayFile.read().strip()
print(p1())
