import re
a="""
Hello, world!
Hello, world!
Hello, world!
“
<ul>
<li>"</li>
</ul>
"
Hello, world!
"""
s=re.escape(a)
r = re.compile(r"\(.)") # Note the parethesis, that's a capturing group
r.sub(r'\1', s).replace("\",''),s # \1 means: replace with value of first capturing group
输出如下
(‘\n\nHello, world!\n\nHello, world!\n\nHello, world!\n“ \n- “\n”\nHello, world!\n\n\n’, ‘\\n\\nHello,\ world!\\n\\nHello,\ world!\\n\\nHello,\ world!\\n“\ \ \\n\-\ “\\n”\\nHello,\ world!\\n\\n\\n’)
