...if you want to accept patterns like
@param[iutttttt]xxxxxxx

The regexp at the top (Adam's original reply) would be the valid
regexp in python and matches all the tests thrown at it, assuming
it's placed in a raw string:
r = re.compile(r"@param\[(in|out)\] \w+")
If it's not a python regexp, this isn't really the list for the
question, is it? ;)
However, things to try:
- sometimes the grouping parens need to be escaped with "\"
- sometimes "\w" isn't a valid character class, so use the
long-hand variant of something like "[a-zA-Z0-9_]]
- sometimes the "+" is escaped with a "\"
- if you don't use raw strings, you'll need to escape your "\"
characters, making each instance "\\"
