Solve the following python programming problem given the following code:
def _get_stat(self) : 
    '
        Get statistics from devfile in list of lists of words
        ' 
    def dev_filter(x) : 
        x = x.strip ().split (' ') [0] [: (- 1)] 
        if (x in self.interfaces_blacklist) : 
            return False 
if self.all_interfaces : 
            return True 
if (x in self.interfaces) : 
            return True 
return False 
x = filter (self, open (self.devfile).readlines () [2 :]) 
    try : 
        return [list (filter ((lambda x : x), _x.split (' '))) for _x in x] 
except StopIteration : 
        return None 

    
    

    Fix the buggy line: x = filter (self, open (self.devfile).readlines () [2 :])
