Solve the following python programming problem given the following code:
def __init__(self, spi, cs = 0) : 
    self.spi = spi 
    self.cs = cs 
    spi.begin () 
    spi.setClockMode (0, 0) 
    spi.setMaxFrequency (0, 3000000) 
    id_val = self.readRegister (fromUnsigned16.REG_ID) [0] 
    assert (id_val == self.ID_VALUE), 'BMP183 not detected on SPI bus' 
    def fromUnsigned16(bytes) : 
        ' Convert register values as unsigned short int ' 
        return ((bytes [0] << 8) | bytes [1]) 
def fromSigned16(bytes) : 
        ' Convert register values as signed short int ' 
        x = fromUnsigned16 (bytes) 
        if (x > 32767) : 
            return (- (65536 - x)) 
return x 
self.cal_AC1 = fromSigned16 (self.readRegister (170, 2)) 
    self.cal_AC2 = fromSigned16 (self.readRegister (172, 2)) 
    self.cal_AC3 = fromSigned16 (self.readRegister (174, 2)) 
    self.cal_AC4 = fromUnsigned16 (self.readRegister (176, 2)) 
    self.cal_AC5 = fromUnsigned16 (self.readRegister (178, 2)) 
    self.cal_AC6 = fromUnsigned16 (self.readRegister (180, 2)) 
    self.cal_B1 = fromSigned16 (self.readRegister (182, 2)) 
    self.cal_B2 = fromSigned16 (self.readRegister (184, 2)) 
    self.cal_MB = fromSigned16 (self.readRegister (186, 2)) 
    self.cal_MC = fromSigned16 (self.readRegister (188, 2)) 
    self.cal_MD = fromSigned16 (self.readRegister (190, 2)) 

    
    

    Fix the buggy line: id_val = self.readRegister (fromUnsigned16.REG_ID) [0]

#Here is Python code to fix the buggy line: id_val = self.

id_val = self.readRegister (self.REG_ID) [0]
