Range in Python
<p>I want to list numbers in range and I want to find out the amount of numbers in range.</p>

<p>For Example:</p>

<pre><code>X = (5,6,5,1,2,3,4,5,6,7)
Y = (5, 5, 5,5 5,5 5,5 5)
range(X) # Want to know how many numbers in X.
</code></pre>

<p>If you guys could help it would be great.</p>
