Solve the following python programming problem given the following code:
def test_odeint_errors() : 
    def sys1d(x, t) : 
        return ((- 100) * x) 
def bad1(x, t) : 
        return (1.0 / 0) 
def bad2(x, t) : 
        return 'foo' 
def bad_jac1(x, t) : 
        return (1.0 / 0) 
def bad_jac2(x, t) : 
        return [['foo']] 
def sys2d(x, t) : 
        return [((- 100) * x [0]), ((- 0.1) * x [1])] 
def sys2d_bad_jac(x, t) : 
        return [[(1.0 / 0), 0], [0, (- 0.1)]] 
assert_raises (ZeroDivisionError, odeint, bad1, 1.0, [0, 1]) 
    assert_raises (ValueError, odeint, bad2, 1.0, [0, 1]) 
    assert_raises (ZeroDivisionError, odeint, sys1d, 1.0, [0, 1], Dfun = bad_jac1) 
    assert_raises (ValueError, odeint, sys1d, 1.0, [0, 1], Dfun = sys1d) 
    assert_raises (ZeroDivisionError, odeint, sys2d, [1.0, 1.0], [0, 1], Dfun = sys2d_bad_jac) 

    
    

    Fix the buggy line: assert_raises (ValueError, odeint, sys1d, 1.0, [0, 1], Dfun = sys1d)
