Yeah, it's legal because you can nest fors and ifs in a list comp. Stylistic difference, I used "if" instead of "and" because there's no way that it could be a bitwise and. (It's a cross-language safety net that I sometimes use.) Although the 10<=i<=20 option is definitely superior to both. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
