<p>What is the regular expression to match strings (in this case, file names) that start with 'Run' and have a filename extension of '.py'?</p>

<p>The regular expression should match any of the following:</p>

<pre><code>RunFoo.py
RunBar.py
Run42.py
</code></pre>

<p>It should not match:</p>

<pre><code>myRunFoo.py
RunBar.py1
Run42.txt
</code></pre>

<p>The SQL equivalent of what I am looking for is <code>... LIKE 'Run%.py' ...</code>.</p>

This probably doesn't fully comply with file-naming standards, but here it goes:
```
```
/^Run[\w]*?\.py$/
```
```
