You can't append to an int, you need to initialise your result list with lists. Instead of result = [0]*NUM_OF_FILE you need result= [ [] for i in range(NUM_OF_FILES) ] In the future, please include the error message you receive when trying to run the program. -- Rich "Roadie Rich" Lovely Just because you CAN do something, doesn't necessarily mean you SHOULD. In fact, more often than not, you probably SHOULDN'T. Especially if I suggested it. 10 re-discover BASIC 20 ??? 30 PRINT "Profit" 40 GOTO 10 _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
