将python字节代码转换为常规python代码

Question

如何将以下字节码转换为普通python代码？我通过反编译一个pyc文件得到了这段代码。一些代码被反编译为其原始代码，但大多数没有。知道我怎样才能把这个字节码转换成它的源代码吗

我建议您使用uncompyle6模块。（您需要原始的.pyc或.pyo文件）。要安装，请运行

~$ pip install uncompyle6

然后，要反编译任何Python字节码文件，请运行

~$ uncompyle6 path/to/bytecode/file.pyc

有关所有可用选项的概述，请运行

~$ uncompyle6 -h

它支持从2.4到3.8的所有Python版本。你可以在https://github.com/rocky/python-uncompyle6找到项目的主页
