validators.Regex in Form Python Flask doesn't work
<p>Currently my program is not accepting any form of regex strings I give my validators. This is the code Im running and it returns me invalid input as a result.</p>

<pre><code>TextField('Number',[validators.Regexp(regex=r'^[0-9]')])
</code></pre>

<p>Doesn't matter if I supply numbers, letters, combination it keeps returning me with Invalid input. Any ideas?</p>
