My intention is to implement a max. length of 8 for an input string. The above 
works well in all other respects, but does allow for strings that are too long.

What is the proper way to fix this?

Thanks for any help!


You could put the end marker $ on your regex so that it won't match if it's not the end.

Or, you know, you could just check len(compval) <= 8 and not get bogged down in regexes. They tend to be excellent solutions to only a very specific complexity of problem.
