I have used numpy.allclose to test for approximate equality in Python for years, but I recently found pytest.approx better, because it lets Pytest interpret the result. For example, with numpy.allclose:
> assert np.allclose(result, 3.061, atol=1e-3, rtol=1e-3)
E assert False
E + where False = <function allclose at 0x7f8fea7efa60>(1.4872, 3.061, atol=0.001, rtol=0.001)
E + where <function allclose at 0x7f8fea7efa60> = np.allclose
