I setup a buildbot worker to test Python 3.x on Android monthly. This month network in the Android emulator is broken and I got an additional test failure:

0:05:28 load avg: 1.21 [376/423/11] test_unicodedata failed
test test_unicodedata failed -- Traceback (most recent call last):
  File "/data/local/tmp/lib/python3.10/urllib/request.py", line 1342, in do_open
    h.request(req.get_method(), req.selector, req.data, headers,
socket.gaierror: [Errno 7] No address associated with hostname

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/data/local/tmp/lib/python3.10/test/test_unicodedata.py", line 329, in test_normalization
    testdata = open_urlresource(TESTDATAURL, encoding="utf-8",
urllib.error.URLError: <urlopen error [Errno 7] No address associated with hostname>

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/data/local/tmp/lib/python3.10/test/test_unicodedata.py", line 335, in test_normalization
    self.fail(f"Could not retrieve {TESTDATAURL}")
AssertionError: Could not retrieve http://www.pythontest.net/unicode/13.0.0/NormalizationTest.txt

I propose wrapping the test in socket_helper.transient_internet() so that this test is skipped if the Internet is not available.

Looks Good To Me

Closing in favor of a simpler fix merged from issue43144. Thanks for the fix!
