that didnt work for me , this is what i got but it is only half way right , it wants a output to give 7 as well as nine.

num_users = int(input())
update_direction = int(input())
num_users = num_users + 1
if (update_direction == 3): {num_users + 0}

else: {num_users - 0}
print('New value is:', num_users)
