  This works</p>
  
  <pre><code>a=1
  b=a
  </code></pre>
  
  <p>it outputs a if you used<code>print(b)</code> you will get 1.But if i used this, </p>
  
  <pre><code> for i in range (0,a1,2):
       r=i/2
       e[r] ='c%s'%i
       print(e[r])
  </code></pre>
  
  <p>(c0, c2, c4,... has a value) 
  then it will output c0, c2, c4... 
  How can i make it output the value of c0,c2,c4...?
  I tried changing the <code>''</code>to<code>" "</code>but it still don't work.</p>
