break help

[tpkemme]

so now that i have gotten farther in the code, it prints the substrings correctly, but i can't get the program to stop correctly. basically, i'm looking for the longest common substring.

def main():
input1 =raw_input('Enter string: ')
input2 = raw_input('Enter second string: ')
if input1 > input2:
str = input2
str2 = input1
elif input2 > input1:
str = input1
str2 = input2
else:
str = input1
str2 = input2
print str, str2

size=len(str)+1
for sub_len in range(size, 0 ,-1):
for idx in range(0, size - sub_len):
sub_str = str[idx : idx + sub_len]

for x in range(len(str)):
if str2.find(sub_str) > -1 and len(sub_str) == len(str) - x:
print sub_str
break

i need help with last part. it correctly finds all the substrings but it doesn't stop at the highest one but instead keeps going. since x is in the range 0-len(str), should the first value of x that is plugged into the following condition be 0? and if it is, how do i get it to stop as soon as the condition is true? because either i put break on the same column as print sub_str and it prints all the substrings or i put it on the same column as the if conditional and it only works if the substring is one of the original strings. any helP?

Maybe more exactly (code start tag misspelled to get the code tag work here):

while poster.isnewbie() and post.hascode() and not '[ CODE]' in post:
    print("Be kind and add code tags around your code when posting or you lose indention")
