How to fetch the status of test-case in teardown, after each test-case completion (pyunit)?

Question

Executing few test-cases as part of test-suite. Goal is to skip test-case, if there is any failure in previous test-cases or any dependency.

class New():
    global status
    status = []
    
    def setUp(self):
        self.browser = None
    
    def test_1(self):
        print("1")
    
    def test_2(self):
        print(2)
        assert False
    
    def test_3(self):
        if 'test_2' in status:
            self.skipTest("test_2 FAILED")
        print(3)
        # assert False
    
    def test_4(self):
        if any(x in ['test_2', 'test_3'] for x in status):
            self.skipTest("test_2 or test_3 FAILED")
        print(4)
      
    def test_5(self):
        print(5)
        
    def list2reason(self, exc_list):
        print("EXEC LIST : {}".format(exc_list))
        if exc_list and exc_list[-1][0] is self:
            print(exc_list[-1][0])
            return exc_list[-1][1]


    def tearDown(self):
        if self.browser:
            super().tearDown(close_browser=False)
            self.browser.quit()
        if hasattr(self, '_outcome'):  # Python 3.4+
            result = self.defaultTestResult()  # these 2 methods have no side effects
            self._feedErrorsToResult(result, self._outcome.errors)
        else:  # Python 3.2 - 3.3 or 2.7
            result = getattr(self, '_outcomeForDoCleanups', self._resultForDoCleanups)
        error = self.list2reason(result.errors)
        failure = self.list2reason(result.failures)
        skipped = self.list2reason(result.skipped)
        print("error : {} , failure : {}, skipped: {}".format(error, failure, skipped))
        ok = not error and not failure

        # demo:   report short info immediately (not important)
        if not ok:
            status.append(self._testMethodName)
            typ, text = ('ERROR', error) if error else ('FAIL', failure)
            msg = [x for x in text.split('\n')[1:] if not x.startswith(' ')][0]
            print("\n== tearDown check: %s: %s\n     %s" % (typ, self.id(), msg))

However, I am unable to capture the skipped status. It always shows None, though test-cases skipped. And skipIf(condition) doesn't seem to be working. So, using SkipTest inside test. Am i missing anything here ?
