Python declaring multiple variables as lists
<p>Is the below declaration wrong? It doesnt give any syntax error though but some times i see that <code>b</code> and <code>a</code> value append operations do not work in case of a list.</p>

<pre><code>a=b=c=[]
 or 
a=b=c={}

a=b=c=1 //works
</code></pre>
