這段代碼想實作點菜，撤銷，結賬，現在撰寫了一段代碼想要加入進去，可是選擇4無法實行，求大神幫忙修改，萬分感謝，還望修改后的代碼能夠整段告知，如上列代碼有不足之處，請您幫忙修改，謝謝

前兩天有人問【結賬】功能如何實作你們會不會是同一個學校的？

錯誤資訊：list index out of range，很清楚了，你串列超出范圍溢位了。這種問題很好解決，你自己在報錯地方設個斷點，看看你那兩個menu3和price串列都是什么，多少個元素；你再看看你for回圈的范圍1-8，i是不是超出那兩個串列的范圍了，你就知道怎么改了(如果代碼是你自己寫的)轉載請註明出處，本文鏈接：https://www.uj5u.com/qita/118002.html
