Solve the following python programming problem given the following code:
def _run_solout_break_test(self, integrator) : 
    ts = [] 
    ys = [] 
    t0 = 0.0 
    tend = 20.0 
    y0 = [0.0] 
    def solout(t, y) : 
        ts.append (t) 
        ys.append (y.copy ()) 
        if (t > (tend / 2.0)) : 
            return (- 1) 
def rhs(t, y) : 
        return [(1.0 / ((t - 10.0) - 1j))] 
ig = complex_ode (rhs).set_integrator (integrator) 
    ig.set_solout (solout) 
    ig.set_initial_value (y0, t0) 
    ret = ig.integrate (tend) 
    assert_array_equal (ys [0], y0) 
    assert_array_equal (ys [(- 1)], ret) 
    assert_equal (ts [0], t0) 
    assert_ ((ts [(- 1)] > (tend / 2.0))) 
    assert_ ((ts [(- 1)] < self)) 

    
    

    Fix the buggy line: assert_ ((ts [(- 1)] < self))
assistant
#Here is Python code to fix the buggy line: assert_ ((ts [(- 1)] < self))
.

assert_ ((ts [(- 1)] < tend))
