Test Failure: AssertionError in test_doctests

[Aniketsy]

I noticed one doctest failure in test_tables.py (line 121) during the CI checks.

   def test_doctests():
        results = doctest.testmod(tables, optionflags=doctest.NORMALIZE_WHITESPACE)
>       assert results.failed == 0
E       assert 1 == 0
E        +  where 1 = TestResults(failed=1, attempted=362).failed

tests/test_tables.py:121: AssertionError

@davidwagner Could you please review and confirm whether this failure is expected or unrelated to my changes? I’d be happy to fix it once confirmed.

I can't tell which doctest is failing, so I'm not sure, but my immediate reaction is that I wasn't expecting any failures in any of the tests.

[Aniketsy]

Sure, I’ll look into this and update this with a fix.

My current hypothesis is that this might have been a transient error with the textbook website. The error occurred with the following code:

Table.read_table('https://www.inferentialthinking.com/data/sat2014.csv')

That doesn't seem to produce an error for me currently. So merely re-running the CI tests might make the error go away, if I'm right. I can't immediately see how to trigger a re-run of the automated CI tests, though.
