def test_magnitude_of_a_normalized_vector():
    # Given
    v = Vector(1, 2, 3)
    # When
    norm = v.normalize()
    # Then
    assert norm.magnitude() == 1

Example #2

def test_normalizing_vector_1_2_3():
    # Given
    v = Vector(1, 2, 3)
    # Then
    assert v.normalize() == Vector(1 / sqrt(14), 2 / sqrt(14), 3 / sqrt(14))

Example #3

def test_normalizing_vector_4_0_0_gives_1_0_0():
    # Given
    v = Vector(4, 0, 0)
    # Then
    assert v.normalize() == Vector(1, 0, 0)
