Python如何拆分包含转义符作为分隔符的字符串？

Question

如何在“\x”处拆分以下字符串？我遇到了麻烦，因为“\”是一个转义字符。你知道吗

MyString = 'A\x92\xa4\xbf'
delim = '"\"' + 'x'
MyList = MyString.split(delim)
print(MyList)

附加细节：4192A4BF是“低序列号”，显示为XCTU程序中Xbee无线电的序列号，Digi使用该程序配置Xbee无线电。你知道吗

在xbee上使用micropython检索序列号：serial = xbee.atcmd("SL")返回'A\x92\xa4\xbf'，这是我所知的hex（A）后跟92A4BF。如果在“\x”处拆分，则可以提取与XTCU上相同的数字。你知道吗

Answer 1

通过执行r'string'

试试这个：

MyString = r'A\x92\xa4\xbf'
delim = '\\' + 'x'  #OR simply: delim = '\\x'
MyList = MyString.split(delim)
print(MyList)

输出：

['A', '92', 'a4', 'bf']

此技术适用于任何转义序列（让我知道xD）\x，只需将分隔符设置为\\x。工作示例：https://repl.it/@stupidlylogical/RawStringPython

工作原因：

Python raw string treats backslash (\) as a literal character. This is useful when we want to have a string that contains backslash and don't want it to be treated as an escape character.

说明：

When an 'r' or 'R' prefix is present, a character following a backslash is included in the string without change, and all backslashes are left in the string.
