or <pre class='brush: python'>return re.sub(r'[^A-Z]', '', text) </pre>

Perhaps not as "intuitive" as re.findall & join, but the re.sub does look neater.

Exactly. I published this solution intuitively (There were no similar solutions).

I definitely need to get a grip on regex... Interesting and neat but also a bit cryptic for newbies like me.

Hi, thanks for your solution. I know only several reg exp functions, and your example taught me another one, ha-ha :3 But here is a question - is it true that 'r' in r'[A-Z]' isn't necessary?

Yes! I knew there must have been a better substitute for .sub for this task...
