Problem 1: Spelling Write a regular expression that matches violations of the old spelling rule "I before E except after C or when sounded like A as in neighbor or weigh" \[ \text { SPELL_RE }=r^{\prime} \] The following code block will test your regular expression by trying it against a bunch of strings. If your answer is correct it should pass 100% of the tests. % WRONG = ('peice', 'beleive', 'greif', 'cieling', 'recieve', 'wieght', 'frieght') RIGHT = ('piece', 'believe', 'grief', 'ceiling', 'receive', 'weight', 'freight') apytest.mark.parametrize('text,is_error', [(x, True) for x in WRONG ]+ def test_spell(text, is_error): [(x, False) for x in RIGHT ]) assert bool(re.search(SPELL_RE, text)) = is_error
