How to surpress python's start-up information?
<p>When I type "python" and return in shell, the following lines will come out:</p>

<pre><code>Python 2.7.1+ (r271:86832, Apr 11 2011, 18:05:24)
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
</code></pre>

<p>How to surpress these lines please?</p>
