numpy.angle() is used when we want to calculate the angle of a complex argument. A complex number is represented as "x + yi", where x and y — real numbers, and
i = (-1) ^ 1/2 . The angle is calculated using the formula
Syntax: numpy.angle (z, deg = 0) p>
z: [array_like] A complex number or sequence of complex numbers.
deg: strong> [bool, optional] Return angle in degrees if True, radians if False (default).
angle: strong > The counterclockwise angle from the positive real axis on the complex plane, with dtype as numpy.float64.
