Cannot Import Counter is encountered in python 2.7.3 on CSH
<p>I am using UNIX's cShell in my Windows 7 OS.<br>
When I am executing a prog. it shows an error every time :<code>can not import name Counter</code>.<br>
though I have mentioned in the script <code>from collections import Counter</code>.<br>
I am using <code>Python 2.7.3</code>, then why this problem is persisting.</p>
