title: Python declaring multiple variables as lists
body: <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>
