使用变量打印原始字节

Question

！解决！

在python 2命令行中运行：

>>> print r"\x72"
\x72

python将返回：\ x72 但如果我这样做：

>>> a = "\x72"
>>> print a
r

它将打印“r”。我也知道如果我这样做：

>>> a = r"\x72"
>>> print a
\x72

但我希望能够做的是：

>>> a = "\x72"

然后制作它以便我可以打印出来，就像它一样：

r"\x73"

如何转换？

编辑： 我打印从服务器收到的字节。

工作解决方案：

def byte_pbyte(data):
    # check if there are multiple bytes
    if len(str(data)) > 1:
        # make list all bytes given
        msg = list(data)
        # mark which item is being converted
        s = 0
        for u in msg:
            # convert byte to ascii, then encode ascii to get byte number
            u = str(u).encode("hex")
            # make byte printable by canceling \x
            u = "\\x"+u
            # apply coverted byte to byte list
            msg[s] = u
            s = s + 1
        msg = "".join(msg)
    else:
        msg = data
        # convert byte to ascii, then encode ascii to get byte number
        msg = str(msg).encode("hex")
        # make byte printable by canceling \x
        msg = "\\x"+msg
    # return printable byte
    return msg

感谢ginginsha，我能够创建一个将字节转换为可打印字节的函数：

def byte_pbyte(data):
    # check if there are multiple bytes
    if len(str(data)) > 1:
        # make list all bytes given
        msg = list(data)
        # mark which item is being converted
        s = 0
        for u in msg:
            # convert byte to ascii, then encode ascii to get byte number
            u = str(u).encode("hex")
            # make byte printable by canceling \x
            u = "\\x"+u
            # apply coverted byte to byte list
            msg[s] = u
            s = s + 1
        msg = "".join(msg)
    else:
        msg = data
        # convert byte to ascii, then encode ascii to get byte number
        msg = str(msg).encode("hex")
        # make byte printable by canceling \x
        msg = "\\x"+msg
    # return printable byte
    return msg

我认为你想要的是逃避你的逃避序列被解释。

a = '\\x72'

为了打印完整的\x72
