Consider:

    infile = open('infilename.txt', 'r')
    for line in infile:
        line = line.rstrip('\n')
        o
        o
        o
    infile.close()

A few notes:

- See http://docs.python.org/lib/built-in-funcs.html for more on
  built-in functions and open() in particular.

- See http://docs.python.org/lib/string-methods.html for more on
  string operations and rstrip() in particular.

- rstrip() with no arguments strips all whitespace on the right.

- A file object (returned by the open() function) is an iterator; it
  obeys the iterator protocol.  That's why you can use it in the
  "for" statement above.
