How to write integers to a file
<p>I need to write </p>

<pre><code>ranks[a], ranks[b], count
</code></pre>

<p>to a file, each time on a new line</p>

<p>I am using:</p>

<pre><code>file = open("matrix.txt", "w")
for (a, b), count in counts.iteritems():
    file.write(ranks[a], ranks[b], count)

file.close()
</code></pre>

<p>but this is not working and returns</p>

<pre><code>TypeError: function takes exactly 1 argument (3 given)
</code></pre>
