Solve the following python programming problem given the following code:
@ with_sitl 
def test_timeout(connpath) : 
    vehicle = connect (connpath, wait_ready = True) 
    vehicle.parameters ['FS_GCS_ENABLE'] = 0 
    vehicle.parameters ['FS_EKF_THRESH'] = 100 
    def arm_and_takeoff(aTargetAltitude) : 
        '
        Arms vehicle and fly to aTargetAltitude.
        ' 
        wait_for ((lambda : vehicle.is_armable), 60) 
        assert_equals (vehicle.is_armable, True) 
        vehicle.mode = VehicleMode ('GUIDED') 
        wait_for ((lambda : (vehicle.mode.name == 'GUIDED')), 60) 
        assert_equals (vehicle.mode.name, 'GUIDED') 
        vehicle.armed = True 
        wait_for ((lambda : vehicle.armed), 60) 
        assert_equals (vehicle.armed, True) 
        vehicle.simple_takeoff (aTargetAltitude) 
        while True : 
            if (vehicle.location.global_frame.alt >= (aTargetAltitude * 0.95)) : 
                break 
assert_equals (vehicle.mode.name, 'GUIDED') 
            time.sleep (1) 
arm_and_takeoff (10) 
    vehicle.wait_ready ('location.local_frame', timeout = 60) 
    assert_not_equals (vehicle.location.local_frame.north, None) 
    assert_not_equals (vehicle.location.local_frame.east, None) 
    assert_not_equals (vehicle.location.local_frame.down, None) 
    assert_not_equals (arm_and_takeoff.location.global_frame.lat, None) 
    assert_not_equals (vehicle.location.global_frame.lon, None) 
    assert_not_equals (vehicle.location.global_frame.alt, None) 
    assert_equals (type (vehicle.location.global_frame.lat), float) 
    assert_equals (type (vehicle.location.global_frame.lon), float) 
    assert_equals (type (vehicle.location.global_frame.alt), float) 
    vehicle.close () 

    
    

    Fix the buggy line: assert_not_equals (arm_and_takeoff.location.global_frame.lat, None)
