PHP的stripslashes的Python版本

Question

我写了一段代码，将PHP的条纹转换为有效的Python反斜杠转义：

cleaned = stringwithslashes
cleaned = cleaned.replace('\\n', '\n')
cleaned = cleaned.replace('\\r', '\n')
cleaned = cleaned.replace('\\', '')

我该如何压缩它呢？

Answer 1

我不确定这是不是你想要的，但是..

cleaned = stringwithslashes.decode('string_escape')

Answer 2

听起来你想要的东西可以通过正则表达式相当有效地处理：

import re
def stripslashes(s):
    r = re.sub(r"\\(n|r)", "\n", s)
    r = re.sub(r"\\", "", r)
    return r
cleaned = stripslashes(stringwithslashes)

Answer 3

使用decode('string_escape')

cleaned = stringwithslashes.decode('string_escape')

使用

string_escape：在Python源代码中生成适合作为字符串文字的字符串

或者像威尔逊的答案那样连接replace()。

cleaned = stringwithslashes.replace("\\","").replace("\\n","\n").replace("\\r","\n")
