Just declaring a variable in Python?
<p>Is it possible to just declaring a variable in Python, like so?:</p>

<p>var</p>

<p>so that it's gonna be initialized to None?</p>

<p>It seems like python allows this, but as soon as you access it, it crashes.</p>

<p>Is this possible? If not, why?</p>

<p>EDIT: I wanna do this for cases like this:</p>

<pre><code>value

for index in sequence:

   if value == None and conditionMet:
       value = index
       break
</code></pre>
