An improvement on the switch-using-dictionaries example: instead of doing this... keycode = 2 functions = {1: key_1_pressed, 2: key_2_pressed, 3: key_3_pre

An improvement on the switch-using-dictionaries example: instead of doing this... keycode = 2 functions = {1: key_1_pressed, 2: key_2_pressed, 3: key_3_pressed} if functions.has_key(keycode): functions[keycode]() else: unknown_key_pressed() you can save three lines by replacing the if-else block with: functions.get(keycode, unknown_key_pressed)()
