python - 如何从字符串生成 vobject

Question

我有一个 Vcard 字符串，我想将其转换为 Vobject：我做了以下操作，但出现了上述错误，我的问题是这个错误是什么，如何将字符串转换为 vcard 对象？

    my_str = "BEGIN:VCARD
              VERSION:3.0
              N;CHARSET=UTF-8:ContactName;;;;
              TEL:0000000000
              END:VCARD"
   vcard = vobject.readOne(my_str)

堆栈跟踪：
