Sometime it maybe a waste to generate all possible combinations of i,j first.
I have googled and found the PEP-3136(Labeled break and continue), which has been rejected. I have also read why Guido rejected this PEP( http://mail.python.org/pipermail/python-3000/2007-July/008663.html), but I still think labeled break and continue is a good feature in my case.
