Python 2 to 3 = TypeError: descriptor 'find' for 'str' objects doesn't apply to a 'bytes' object

Question

您好，我们尝试将 python 2 转换为 3，但遇到错误。也许有人有想法。

谢谢

Python 3 对于混合 str 和 bytes 字符串要严格得多。只要保持一致。当您使用 encode 时，您会创建一个 bytes 字符串。

if bytes.find(episode_num, b".") != -1:

更好，学会使用in:

if b"." in episode_num:
