i just want to check for date validity from within ha same if statemnt like i check the other variables and i tried a regualr expression just now: if( task and ( price and price.isdigit() and price.__len__() <= 3 ) and ( date and re.search( r'(\d+) (\d+) (\d+)', date ) ) ): Do i ahve somehting wrong in it? will the if become true if the user enters 21 02 2013 ? -- http://mail.python.org/mailman/listinfo/python-list
