How do I catch "split" exceptions in python?
<p>I am trying to parse a list of email addresses to remove the username and '@' symbol only leaving the domain name.</p>

<p>Example: blahblah@gmail.com
Desired output: gmail.com</p>

<p>I have accomplished this with the following code:</p>

<pre><code>for row in cr: 
    emailaddy = row[0]
    (emailuser, domain) = row[0].split('@')
    print domain
</code></pre>

<p>but my issue is when I encounter a improperly formatted email address.  For example if the row contains "aaaaaaaaa" (instead of a valid email address) the program crashes with the error </p>

<pre><code>(emailuser, domain) = row[0].split('@')
ValueError: need more than 1 value to unpack. 
</code></pre>

<p>(as you would expect) Rather than check all the email addresses for their validity, I would rather just not update grab the domain and move on to the next record. How can I properly handle this error and just move on?</p>

<p>So for the list of:</p>

<pre><code>blahblah@gmail.com
mmymymy@hotmail.com
youououou
nonononon@yahoo.com
</code></pre>

<p>I would like the output to be:</p>

<pre><code>gmail.com
hotmail.com

yahoo.com
</code></pre>

<p>Thanks!</p>
