import re

compval = 'A123456_8'
regex = '[a-zA-Z]\w{0,7}'

if re.match(regex, compval):

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!
