这工作正常，但目标是获取电子邮件ID列表如下：
['verified_listing@2x-4ab84159ae2ff5f4ecd817beef9ede50.png',
'favorite_notif@2x-6c64c717f1101c319ee357505bbac5cd.jpg',
'activity_empty@2x-307af746773b2fc77d3b5c0ca83d65e9.png',
'rent_back_notif@2x-5682bc7a8194336bf86ec7fb60019037.jpg',
'account_creation@2x-b22082bfcd48013d684a68fb9989180a.jpg',
'top_cities@2x-d268f37ec8600943158855c910fbd9ed.png',
'powered-by-housing@2x-d73306a6a71886351a2b4af5beacd8c6.png']
如何解决这个问题只能获取电子邮件ID而不是其他任何东西。 请帮忙。
