Dear group: I have two lists and I have to match the element in the first list to element in second list and print the line from second list:
Example: listA =['apple','baby','cat'] listB =['fruit\tapple','tree\tapple','fruit\tmango', 'human\tbaby' 'infant\tbaby' 'human\tAlbert' 'animal\tcat' 'tiger\tcat' 'animan\tdog'] I have to take apple, search in listB and print fruit apple tree apple infant baby human baby animal cat tiger cat I am doing it this way: for i in listA: for m in listB: cols = m.split('\t') term = cols[2] if i == term: print m this is very time consuming. Because the two columns in listB are redundant I am unable to do a dict method. The other way could be using a reg.ex method (which I did not try yet because the script written based on equality is still running. for i in listA: pat = re.compile(i) for m in listB: cols = m.split('\t') terms = cols[1] if pat.match(terms): print m Experts, could you please suggest any other method which is fast and does the job correctly. Thank you. Srini __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
