如何从字符串中删除字符直到特殊字符？

Question

I have a string like this.我有一个这样的字符串。

config =\
 {"status":"None",
 "numbers":["123", "123", "123"],
 "schedule":None,
 "data":{
        "x": "y"
        }
}

I would like to remove the config=\\ from the string and get a result like this.我想从字符串中删除 config=\\ 并得到这样的结果。

{"status":"None",
     "numbers":["123", "123", "123"],
     "schedule":None,
     "data":{
             "x": "y"
             }
    }

How can I get this using python regex?我怎样才能使用 python regex 得到这个？ Would like to consider the multiline factor as well!!也想考虑多线因素！！

I am using this method我正在使用这种方法

re.sub(r'.*{"', '{"', script_config, flags=re.MULTILINE)

But the code consider each line separately.但是代码分别考虑每一行。 Also I would like to remove only the我也想只删除

You don't need regexp for it:你不需要正则表达式：

string = string.replace('config =\\\\', '')

If the first word is not specified:如果未指定第一个单词：

string = string[string.find('\\\\')+1:] if '\\\\' in string else string

But if you want to use regexps:但是如果你想使用正则表达式：

string = re.sub(r'^.*\\\\', '', string)
