因此，我正在使用此公共程序来解析此字节数据，但是却收到一个错误，即我正在解析的“字节”对象没有属性“编码”，这是怎么回事以及如何解决？
62 for j in range(4):
63 b = f.read(1)
---> 64 b = b.encode('hex').upper()
65 tmpHex = b + tmpHex
66 tmpHex = ''
AttributeError: 'bytes' object has no attribute 'encode'
我试图用其他方法替换编码，但最终还是收到另一个错误，该错误在上面的第65行说b和tmpHex无法连接。我该如何解决？
我不能包含所有代码，因为stackoverflow表示我的代码太多，编写的东西也很少。

我不得不减少代码，因为我的代码太多，细节也不够。
