Answer 1

You can use

os.walk

See: http://docs.python.org/library/os.html

Answer 2

I'm using path = r"C:\Users\traveler\Desktop":

import os
def all_files_under(path):
   #"""Iterates through all files that are under the given path."""
   for cur_path, dirnames, filenames in os.walk(path):
      for filename in filenames:
         yield os.path.join(cur_path, filename)
latest_file = max(all_files_under('root'), key=os.path.getmtime)

What am i missing here?
