How do I convert a regex with pack and hex from Perl to Python?

I am a newcomer to Python and am converting a 开发者_如何学PythonPerl script. What is the Python equivalent to...

$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;

Any help is greatly appreciated.

You should likely just use urllib.unquote (python 2) / urllib.parse.unquote (python 3), since it looks like that's what the code you provided is trying to accomplish.

value = value.decode('hex')
