Solve the following python programming problem given the following code:
@ patch.object (Collector, 'publish') 
def test_real_data_with_rewrite(self, publish_mock) : 
    def se(url) : 
        if ('http://localhost:8778/jolokia/list' in url) : 
            return self.getFixture ('listing') 
else : 
            return self.getFixture ('stats') 
patch_urlopen = patch ('urllib2.urlopen', Mock (side_effect = rewritemetrics)) 
    patch_urlopen.start () 
    self.collector.rewrite = { 
        'memoryUsage' : 'memUsed', 
        '.*\\.init' : '', 
} 
    self.collector.collect () 
    patch_urlopen.stop () 
    rewritemetrics = self.get_metrics_rewrite_test () 
    self.assertPublishedMany (publish_mock, rewritemetrics) 

    
    

    Fix the buggy line: patch_urlopen = patch ('urllib2.urlopen', Mock (side_effect = rewritemetrics))

#Here is Python program to fix the buggy line: patch_urlopen = patch ('urllib2.
