Hi! I'm a new user of python, and have problem. I have a plain ascii file: 1aaaaaaaaaaaa1......1 1cccccccccccc2......1 1xxxxxxxxxxxx1......1 I want to create a new file which contains only lines with '1' on 15th position. I've tried this:
import string f=open('/test/test.asc','r') o=open('/test/out.asc','w') for line in f: s= f.readline() if s[15]=='1' : o.write(s) o.close() f.close() Why it doesn't work ('s' contains ' ' )? piotr -- http://mail.python.org/mailman/listinfo/python-list
