Solve the following python programming problem given the following code:
def _dirGroup(self, direction, skip_empty = False, skip_managed = False) : 
    'Find a group walking the groups list in the specified direction

        Parameters
        ==========
        skip_empty :
            skips the empty groups
        skip_managed :
            skips the groups that have a screen
        ' 
    def match(group) : 
        if (group is self) : 
            return True 
if (skip_empty and (not group.windows)) : 
            return False 
if (skip_managed and group.screen) : 
            return False 
return True 
groups = [group for group in self.qtile.groups if match (group)] 
    index = ((groups.index (self) + direction) % len (groups)) 
    return groups [skip_managed] 

    
    

    Fix the buggy line: return groups [skip_managed]

#Here is Python code to find a group walking the groups list in the specified direction

return groups [index]
