The programming language Python has a built-in type for complex numbers. A separate algorithm implementing all common arithmetical operations is not needed. In Python, the imaginary unit \(i\) is denoted with the letter \(j\).
z1 = complex(3, 4) z2 = complex(-2, 5)
print(z1) print(z2) print(z2.conjugate()) print(z2.real) print(z2.imag) print("-----------")
print(z1 + z2) print(z1 - z2) print(z1 * z2) print(z1 / z2) print(abs(z2))
