Python-simpy bitwise or
<p>Now I learn the <code>simpy</code> library of python.
Could you explain me why <code>bitwise-or</code> is used in this <a href="https://simpy.readthedocs.org/en/latest/examples/bank_renege.html" rel="nofollow">example</a>. Why we can't use simple <code>or</code> statement. </p>

<pre><code>results = yield req | env.timeout(patience)
