consider model.php : class model { protected static $class_name; protected static $table_name; protected $id; public static function initialize() { static::$class_name = get_called_class(); static::$table_name = strtolower(static::$class_name).'s'; } } and children, user.php , product.php : class user extends model { protected $username; protected $password; } user::initialize(); class product extends model { protected $name; protected $price; } product::initialize(); since every user or product have same $class_name , $table_name , makes sense make them static . actual values assigned when initialize() method called on child model (e.g. user::initialize(); , product::initialize(); ). problem i expect end following: user -> $class_name -> 'user', $table_name -> 'users' product -> $class_name -> 'product', $table_name -> 'products' yet followin...

new programmer here i'm trying ask user choose between 2 options can't right. inp = int(input()) while inp != 1 or inp != 2: print("you must type 1 or 2") inp = int(input()) if inp == 1: print("hi") if inp == 2: print("ok") quit() even if enter 1 or 2 when ask still spits "you must must type 1 or 2" my end goal if enter 1, continue program while if choose 2 end program. help. just work strings. if need turn "inp" variable integer, don't wrap int() function around input(), wrap variable (i.e. int(inp) ). also, change ors ands: inp = "" while inp != "1" , inp != "2": inp = input("enter 1 or 2: ") if inp != "1" , inp != "2": print("you must type 1 or 2") if inp == "1": print("hi") if inp == "2": print("ok")
