Multiplication of complex number Given two complex numbers. The task is to multiply them. My answer: def complexNumberMultiply(a, b): sa = a.split('+') a1 = sa[0] a2 = sa[1] sb = b.split('+') b1 = sb[0] b2 = sb[1] ab1 = str(int((float(a1)*float(b1)) + (float(a2.strip('i'))*float(b2.strip('i')) * -1))) ab2 = str(int((float(a1)*float(b2.strip('i'))+(float(a2.strip('i'))*float(b1)))))+'i' return ab..
