Python update already printed line.

Hi. I have a basic script in python that outputs like this..

Code:
$ ./test.py
1%
2%
3%
4%
5%
6%
7%
8%
9%
10%
...

But how can I make it so the output stays in 1 line?
So it would look something like this..
Code:
$ ./test.py
10%

..after the script got to 10%. So it just updated but printed on the same line.
I've seen this done before i just want to know how to do it. Any ideas?

use print with comma at the end (no newline) and output a \r at the beginning of your print... see if that helps.

You may have to investigate using a terminfo or curses library... what I put above won't clear the line... you can fake it by always outputting enough to blank out the old data (uses spaces for example).
