Python: how to conceal input
<p>How do you conceal the input of <code>raw_input</code>? For example, I want:</p>

<pre><code>password = raw_input("Password: ")
</code></pre>

<p>To be</p>

<pre><code>Password: ********
#or
Password: #hide the characters (i.e. no echo)
</code></pre>

<p>Instead of displaying the string. How can I do so?</p>
