Python _pt Examples

Example #1

def test__pt():
    from sympy.solvers.inequalities import _pt
    assert _pt(-oo, oo) == 0
    assert _pt(S(1), S(3)) == 2

    assert _pt(x, oo) == _pt(oo, x) == x + 1
    assert _pt(x, -oo) == _pt(-oo, x) == x - 1
    raises(ValueError, lambda: _pt(Dummy('i', infinite=True), S(1)))
