在python中复数怎么表示

class Complex(object):

    '''创建一个静态属性用来记录类版本号'''

    version=1.0

    '''创建个复数类，用于操作和初始化复数'''

    def __init__(self,rel=15,img=15j):

        self.realPart=rel

        self.imagPart=img

    #创建复数

    def creatComplex(self):

        return self.realPart+self.imagPart

    #获取输入数字部分的虚部

    def getImg(self):

        #把虚部转换成字符串

        img=str(self.imagPart)

        #对字符串进行切片操作获取数字部分

        img=img[:-1]

        return float(img) 

def test():

    print "run test..........."

    com=Complex()

    Cplex= com.creatComplex()

    if Cplex.imag==com.getImg():

        print com.getImg()

    else:

        pass

    if Cplex.real==com.realPart:

        print com.realPart

    else:

        pass

    #原复数

    print "the religion complex is :",Cplex

    #求取共轭复数

    print "the conjugate complex is :",Cplex.conjugate()

if __name__=="__main__":

    test()
