我将 4 个相同长度的列表和列表的长度传递给我的模板。如何遍历列表？

视图.py

def allbooks(request):
    ID = [1,2]
    bookName = ["Python", "Java"]
    author = ["idk", "who"]

全书.html

                    <td>{{bookName[x]}}</td>
                    <td>{{author[x]}}</td>
                    <td>{{copies[x]}}</td>
                </tr>
