You are trying to use the *string* module without importing it, I'd guess. Try: import string first then you should be able to access string.join without error. Now *I* am confused.

intended at all, which is considered an error. In your second attempt you intended only the first 5 lines. So those (and only those) are repeated. The next line ("if mindist > us_dist(15):") wasn't intended and therefore *not* repeated. If you just learning programming with Python you migth want to start with smaller examples to understand the syntax better.
