Python SyntaxError: invalid syntax when implementing bbcodepy

Question

I got bbcodepy and I'm allowed to modify it, but I can't import it in my main.py. I keep getting a SyntaxError and I don't really know what's wrong with the code because I didn't write it. I just want to tinker around a little bit and see if I can get it to fill my needs. Here's an image pointing me in the direction of the syntax error. But I noticed the same code is written on the same line and I don't get the SyntaxError for that. Here's the code:

_URL_RE = re.compile(ur'''\b((?:([\w-]+):(/{1,3})|www[.])(?:(?:(?:[^\s&()]|&amp;|&quot;)*(?:[^!"#$%&'()*+,.:;<=>?@\[\]^`{|}~\s]))|(?:\((?:[^\s&()]|&amp;|&quot;)*\)))+)''')

The problem appears to be "[^\s&()]" but only the second one, not the first one. If you look closely in the code you'll see that the same thing appears twice, but I only get the SyntaxError on the second appearance. Someone enlighten me, please. I've been trying to find a decent BBCode parser for Python for a couple of days now and I believe this is the one I can modify to my needs. I can't seem to get bbcode to work as I want it to, so I'm trying this out.

Well, Python version 3.4 and above does not support a 'UR' prefix.

You need to execute your code with Python 2.7, or change to line into:

_URL_RE = re.compile(r'''\b((?:([\w-]+):(/{1,3})|www[.])(?:(?:(?:[^\s&()]|&amp;|&quot;)*(?:[^!"#$%&'()*+,.:;<=>?@\[\]^`{|}~\s]))|(?:\((?:[^\s&()]|&amp;|&quot;)*\)))+)''')

See also: python version 3.4 does not support a 'ur' prefix

Note: consider avoiding triple-quoted string because if you insert a newline, it can change the meaning of the regex (unless it is compiled in VERBOSE mode).
