How to write a csv with a comma as the decimal separator?
<p>I am trying to create a european-formatted csv in python. I already set the separator to a semicolon</p>

<pre><code>writer = csv.writer(response, delimiter=';', quoting=csv.QUOTE_ALL)
</code></pre>

<p>However, this still uses dot <code>.</code> as the decimal separator. What's the correct way to make it use a comma, as is correct for my locale? 
I can't seem to find any way to set it in the docs. (I am using, and would prefer to stick to, the built-in <code>csv</code> module)</p>
