At this moment it was done by
def to1byte(matchobj):
....return chr(int('0x' + matchobj.group(1), 16))
s1 = re.sub(r'\\x([0-9a-fA-F]{2})', to1byte, s0)
But, is it that difficult on doing this simple thing?
import codecs
codecs.decode(r"\x68\x65\x6c\x6c\x6f\x0a", "unicode-escape")
'hello\n'
Thank you. What I really want to handle is to any r'\xdd'. The r'\x0a' is for
example. Sorry, didn't describe it clearly:-)
Hm, codecs.decode() does work for arbitrary escapes. It will produce the
same result for r"\xdd"-type raw strings where d is in the range 0...F.
It will also convert other escapes like
>>> codecs.decode(r"\t", "unicode-escape")
'\t'
>>> codecs.decode(r"\u5728", "unicode-escape")
'在'
