They're really not all that common.

Well, you could do it with try/raise, like
   try:
     for i in xrange(1,n+1):
       for j in xrange(1, n+1):
         if i+j > n: raise 'foo'
       ...
   except 'foo': 
     ...

but more normally you'd just say
   for i in xrange(1,n+1):
      for j in xrange(1, n-i+1):
          ...
