Exercise 2 solution

    import re

    html = '<p>Hello <i>big</i> and <i>small</i> world, <i>end</i></p>'
    print(re.findall(r"<i>.*</i>", html))
    print(re.findall(r"<i>([^<]*)</i>", html))
    # ['<i>big</i> and <i>small</i> world, <i>end</i>']
    # ['big', 'small', 'end']

(All lines were run and printed exactly what is shown.)

Explanation: the greedy .* runs to the last closing tag it can find, so the
three items come back as one long match. The negated class [^<]* only allows
characters that are not an opening angle bracket, so each match must stop at
the first closing tag, and the group returns just the words.
