Attribute error when trying to instantiate the graph object in python3.5 #158

I am using OrientDB and Rexster with the latest release of Bulb in python3.5

When I try:

from bulbs.config import Config
from bulbs.rexster import Graph

g = Graph(Config('http://localhost:8182/graphs/Freeth'))

I get the following error:

  File "/home/kevin/Code/python/falcon/freeth/app/models.py", line 7, in <module>
    graph = Graph(Config('http://localhost:8182/graphs/Freeth/'))

AttributeError: can't set attribute

However, there is no problem with python3.4.

Here is the updated function in groovy.py:

def _get_group_pattern(self,flags):
    # combine phrases into a compound pattern
    patterns = []
    sub_pattern = sre_parse.Pattern()
    sub_pattern.flags = flags
    for phrase, action in self.lexicon:
        gid = sub_pattern.opengroup()
        patterns.append(sre_parse.SubPattern(sub_pattern, [
            (SUBPATTERN, (len(patterns) + 1, sre_parse.parse(phrase, flags)$
            ]))
        sub_pattern.closegroup(gid, patterns[-1])
    #sub_pattern.groups = len(patterns) + 1
    group_pattern = sre_parse.SubPattern(sub_pattern, [(BRANCH, (None, patt$
    return sre_compile.compile(group_pattern)
