What I ran was more like the version below, but i did a quick separation of the line that has the ';' in it and goofed. >>> def interv2(inlist): ... for i,val in enumerate(inlist): ... if i==0: ... tmp = val ... elif val != valinc: ... yield [tmp, valinc]; tmp = val ... valinc = val+1 ... yield [tmp, valinc] ... >>> list(interv2(inlist)) [[3, 4], [6, 9], [12, 14], [15, 16]] -- http://mail.python.org/mailman/listinfo/python-list
