    <p>Your question is awkwardly phrased, but I think by <em>'read an unspecified number'</em> what you are looking for is generating a random value - in which case, you want <code>random.randint()</code>.</p> <pre><code>&gt;&gt;&gt; import random &gt;&gt;&gt; random.randint(1, 100) 17 &gt;&gt;&gt; random.randint(1, 100) 30 &gt;&gt;&gt; random.randint(1, 100) 84 </code></pre> <p>Also note that you don't need to do so many loops to achieve what you are trying to do. If you are looping over a range of indices in python rather than looping over the list itself, you are doing something wrong. In this case, it's far easier to use <a href="http://docs.python.org/3/library/functions.html#sum" rel="nofollow">the built in <code>sum()</code> function</a>.</p> <pre><code>&gt;&gt;&gt; import random &gt;&gt;&gt; numbers = [random.randint(0, 100) for _ in range(100)] &gt;&gt;&gt; numbers [45, 81, 46, 80, 67, 57, 72, 47, 87, 13, 5, 56, 87, 5, 74, 7, 88, 1, 36, 48, 97, 39, 16, 31, 52, 30, 14, 58, 43, 17, 70, 85, 37, 49, 28, 1, 33, 73, 90, 86, 75, 42, 27, 91, 100, 86, 59, 85, 43, 59, 27, 24, 11, 56, 95, 36, 3, 10, 40, 42, 10, 71, 75, 10, 69, 86, 63, 6, 56, 95, 91, 31, 40, 13, 5, 5, 31, 28, 36, 94, 22, 77, 100, 36, 98, 85, 23, 61, 92, 94, 17, 91, 25, 43, 55, 7, 9, 57, 14, 39] &gt;&gt;&gt; average = sum(numbers)/len(numbers) &gt;&gt;&gt; average 49 &gt;&gt;&gt; sum(number &gt; average for number in numbers) 46 &gt;&gt;&gt; sum(number &lt; average for number in numbers) 53 </code></pre> <p>Here I have also used <a href="http://www.youtube.com/watch?v=t85uBptTDYY" rel="nofollow">list comprehensions and generator expressions</a>, which are useful for these kind of operations.</p> <p>Alongside this, <code>eval()</code> is a really bad way to get a number from a string. Use <code>int(some_string)</code> instead.</p>

    2. CO@JonClements As he uses ``eval()`` on ``input()``, we can presume he is using 3.x, where we don't need to do that. In 2.x, that or ``from __future__ import division`` would be necessary.

    3. COExcellent point! I keep forgetting 3.x does true division :(

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
