Hello, I have two lists.
alist = ['label', 'guid'] blist = ['column0label', 'column1label', 'dimension0guid', 'description', 'columnid'] I want to iterate over blist and extract the items that match my substrings in alist; alternatively, throw out the items that aren't in alist (but, I've had bad experiences removing items from lists "in place," so I tend toward the "copy" motif.) In real life, blist column entries could have embedded column numbers from 0 to 19. I can do this with excrutiatingly painful 'for' loops. Looking for something more efficient and elegant. Thanks. mp -- Michael Powe [email protected] Naugatuck CT USA "The secret to strong security: less reliance on secrets." -- Whitfield Diffie
