Python Challenge level 3: “re”
Level 3 is the last of these initial text processing problems. Everything quite easy for now.
Hint 1: One small letter, surrounded by EXACTLY three big bodyguards on each of its sides.
#!/usr/bin/env python
import re
mess = open("03.txt").read()
print ''.join(re.findall('[^A-Z][A-Z]{3}([a-z])[A-Z]{3}[^A-Z]',
mess))

From linkedlist.html we’re sent to linkedlist.php, and up to Level 4.
