Can't find infinite loop in this while loop in Python

The code below produces an infinite loop that I can't quite place. Would you please help me find the infinite loop?

while count <= 25:
    randnum = random.randint(1,25)
    int(randnum)
    rindex = randnum - 1
    if randnum not in seats:
        if seats[rindex - 1] and seats[rindex + 1] != 0:
        seats[rindex] = randnum
        count += 1
    else:
        count += 0
else:
        count += 0
