Question

Once again working on Project Euler, this time my script just hangs there. I’m pretty sure I’m letting it run for long enough, and my hand-trace (as my father calls it) yields no issues. Where am I going wrong?

I’m only including the relevant portion of the code, for once.

def main():
    f, n = 0, 20
    while f != 20:
        f = 0
        for x in range(1,21):
            if n % x != 0: break
            else: ++f
        if f == 20: print n
        n += 20

Thanks in advance!

Python doesn’t have increment (++). It’s interpreted as +(+(a)). + is the unary plus operator, which basically does nothing. Use += 1
