python numpy.savetxt header has extra character # : <p>I am using the following to save the numpy array x with a header:</p>

<pre><code>np.savetxt("foo.csv", x, delimiter=",", header="ID,AMOUNT", fmt="%i")
</code></pre>

<p>However, if I open "foo.cv", the file looks like:</p>

<pre><code># ID,AMOUNT
21,100
52,120
63,29
:
</code></pre>

<p>There is an extra <code>#</code> character in the beginning of the header. Why is that and is there a way to get rid of it?</p>
