Problem with ifs and fors

Name: Anonymous 2011-08-14 7:18

I've only recently started trying to learn Python; I'm using Project Euler for some practice, and I'm currently doing Problem 24

I'm sure my code is not the most efficient out there, and it looks quite silly, but it gives me the correct answer and doesn't take too long, so I'm happy with it for now.

I have it printing out the correct answer, but then the program is still running, working out the next numbers in the sequence. I'd appreciate any help in getting my program to stop running once it's output the correct answer. Here is my code:

for b in range(0,10):
    if b != a:
        for c in range(0,10):
            if c not in (a,b):
                for d in range(0,10):
                    if d not in (a,b,c):
                        for e in range (0,10):
                            if e not in (a,b,c,d):
                                for f in range(0,10):
                                    if f not in (a,b,c,d,e):
                                        for g in range(0,10):
                                            if g not in (a,b,c,d,e,f):
                                                for h in range(0,10):
                                                    if h not in (a,b,c,d,e,f,g):
                                                        for i in range(0,10):
                                                            if i not in (a,b,c,d,e,f,g,h):
                                                                for j in range(0,10):
                                                                    if j not in (a,b,c,d,e,f,g,h,i):
                                                                        z = 1000000000*a + 100000000*b + 10000000*c + 1000000*d + 100000*e + 10000*f + 1000*g + 100*h + 10*i + j
                                                                        m = m + 1
                                                                        if m == 1000000:
                                                                            print z
