好吧，我正在尝试清理包含法语口音代码的文件：

#353= IFCPROPERTYSINGLEVALUE('Charge d''\X2\00E9\X0\clairage sp\X2\00E9\X0\cifi\X2\00E9\X0\e par surface',$,IFCREAL(10.7639104167097),$);

我创建了这个小功能：

def CleanSpace(sp):
    sp.replace("\X2\00F4\X0\","ô")
    sp.replace("\X2\00E9\X0\","é")
    return(sp)

但是 Python 3 给了我错误：

    sp.replace("\X2\00F4\X0\","ô")
                               ^
SyntaxError: invalid syntax

请问我该如何解决？提前致谢

编辑：如果有帮助，我宁愿在控制台中尝试这一行，但答案很奇怪：

$ python3

\ 字符会转义您的引号。这意味着 python 将继续运行，直到找到另一个引号来结束您的字符串。所以，实际上，你的字符串是\X2\00F4\X0\",为了解决这个问题，用 \ 转义 \ 或完全删除最后一个。新代码：

sp.replace("\X2\00F4\X0\\","ô")

Well, after a lot of tries and searches, solution for one line was to use raw-strings:

>>> a.replace(r'\X2\00E9\X0\ '[:-1], 'é')
"#353= IFCPROPERTYSINGLEVALUE('Charge d''éclairage spécifiée par surface',$,IFCREAL(10.7639104167097),$);"

For more lines, it was more difficult because bytes into my file are already written and it is not because I see a '\' that it is existing... Solution found for me was to work on bytes with antlr4
