<code>str(s or '')</code></p>
<p>Because None is False, and "x or y" returns y if x is false. See <a href="http://docs.python.org/library/stdtypes.html#boolean-operations-and-or-not">Boolean Operators</a> for a detailed explanation. It's short, but not very explicit.</p>

Python: most idiomatic way to convert None to empty string? | 1,034,573 | <p>What is the most idiomatic way to do the following?</p>
<pre><code>def xstr(s):
if s is None:
return ''
else:
return s
s = xstr(a) + xstr(b)
</code></pre>

max("Hello",'') #Returns Hello
</code></pre>
<p>Works like a charm ;) Just put your string in the first parameter of the function.</p>

Obtaining references to function objects on the execution stack from the frame object? | 1,034,688 | <p>Given the output of <code>inspect.stack()</code>, is it possible to get the function objects from anywhere from the stack frame and call these? If so, how?</p>

Finding Nth item of unsorted list without sorting the list | 1,034,846 | <p>Hey. I have a very large array and I want to find the Nth largest value.
