This is awfully hard to read -- any reason you're trying to cram so much
stuff on one line? Is this what you are trying to do?

for x in range(20000):
    for y in range(2, 7):
        if x % y == 1 and x % 7 == 0:
            print x
            break

If so, it will be easy to start altering from there.
