Solve the following python programming problem given the following code:
def _split_channels(self, s) : 
    'Split the color into color channels: red, green, blue, alpha.' 
    def alpha_channel(alpha) : 
        'Get alpha channel.' 
        return (int (alpha, 16) if alpha else 255) 
m = self.color_pattern.match (s) 
    assert (m is not None) 
    if m.group (1) : 
        return (int (self [1 : 3], 16), int (s [3 : 5], 16), int (s [5 : 7], 16), alpha_channel (m.group (2))) 
else : 
        return (int ((s [1] * 2), 16), int ((s [2] * 2), 16), int ((s [3] * 2), 16), 255) 

    
    

    Fix the buggy line: return (int (self [1 : 3], 16), int (s [3 : 5], 16), int (s [5 : 7], 16), alpha_channel (m.group (2)))

#Here is Python program to fix the buggy line: return (int (self [1 : 3], 16), int (s [3 : 5], 16), int (s [5 : 7], 16), alpha_channel (m.

return (int (s [1 : 3], 16), int (s [3 : 5], 16), int (s [5 : 7], 16), alpha_channel (m.group (2)))
