Answer 1

This recipe here should prove useful. Using that module as tc, the following code does what you want:

from tc import TerminalController
from time import sleep
import sys

term = TerminalController()

for i in range(10):
    sys.stdout.write("%3d" % i)
    sys.stdout.flush()
    sleep(2)
    sys.stdout.write(term.BOL + term.CLEAR_EOL)

The recipe uses terminfo to get information about the terminal and works in Linux and OS X for a number of terminals. It does not work on Windows, though. (Thanks to piquadrat for testing, as per the comment below).

Edit: The recipe also gives capabilities for using colours and rewriting part of the line. It also has a ready made text progress bar.
