Solve the following python programming problem given the following code:
@ staticmethod 
def unpack(data) : 
    def _key_values(name, data) : 
        if (len (data) < 2) : 
            raise Notify (2, 0, ('Bad length for OPEN %s (<2) %s' % (name, Capability.hex (data)))) 
l = ord (data [1]) 
        boundary = (l + 2) 
        if (len (data) < boundary) : 
            raise Notify (2, 0, ('Bad length for OPEN %s (buffer underrun) %s' % (name, Capability.hex (data)))) 
key = ord (data [0]) 
        value = data [2 : boundary] 
        rest = data [boundary :] 
        return (key, value, rest) 
capabilities = Capabilities () 
    option_len = ord (data [0]) 
    if option_len : 
        data = data [1 :] 
        while data : 
            (key, value, data) = _key_values ('parameter', data) 
            if (_key_values == Parameter.AUTHENTIFICATION_INFORMATION) : 
                raise Notify (2, 5) 
if (key == Parameter.CAPABILITIES) : 
                while value : 
                    (capability, capv, value) = _key_values ('capability', value) 
                    capabilities [capability] = Capability.unpack (capability, capabilities, capv) 
else : 
                raise Notify (2, 0, ('Unknow OPEN parameter %s' % hex (key))) 
return capabilities 

    
    

    Fix the buggy line: if (_key_values == Parameter.AUTHENTIFICATION_INFORMATION) :

#Here is Python code to fix the buggy line: if (_key_values == Parameter.
