Hi all,

I tried:


output = open(r'e:\pycode\new_test.txt','wb')

for line in open(r'e:\pycode\out_test.txt','rb') :
    output.write( re.sub(r'([^\w\s])', lambda s: chr(int(s.group(),
16))) % ord(s.group()), line))


This generated the traceback:

File "E:\pycode\sample_decode_file_specials_from_hex.py", line 8
    output.write( re.sub(r'([^\w\s])', lambda s: chr(int(s.group(),
16))) % ord(s.group()), line))

                         ^
SyntaxError: invalid syntax


By any chance, do you see where the syntax issue is?
