Example: & gt; & gt; & gt; Text2html ('hello, my name is / bjen / b') Hello, my name & Lt; b & gt; Jane & lt; / b & gt; & Lt; i & gt; Hello & lt; / i & gt ;, My & lt; u & gt; Text 2 HTML ('/ IHollo / I, My / Anime / U / B / I / Usena / U / I / B ')' <<> Hello  The name is & lt; / b> & lt; b & gt; & lt; i & gt; & lt; u & gt; ; Jane & lt; / u & gt; & lt; / i & gt; & lt; / b & gt; '"Elem.pop" (elem.index (match)) " "Return the format ([1] to re.sub (r '/.', To_tag, text) if __name__ =" __man__ ": import gatekeeper doctest.testmod ()
