You may solve it using one of the approaches below
* 1. Simple (to understand) solution: * >>> m = 0 >>> def mIncrementer(): ... global m ... m += 1 ... return m >>> mIncrementer() 1 >>> mIncrementer() 2 * 2. Best solution (Pythonic)* >>> import itertools >>> c = itertools.count(9) >>> c.next() 9 >>> c.next() 10 _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
