current_users = ['Tifa', 'Ada', 'Lightning', 'Lion', 'Natasha']new_users = ['Tifa', 'Ada', 'Lucifer', 'liON', 'Michael']#下面是我寫的代碼,該如何在用戶名為liON時(shí)打印出'Username is uese'？for new_user in new_users:? ? print(new_user)? ? if new_user in current_users:? ? ? ? print('Username is uesd')? ? else:? ? ? ? print('Username is not used')
怎么寫才能在比較時(shí)候不區(qū)分大小寫？Lion和liON不區(qū)分大小寫對比，并打印出已被占用。
