Assume I'm working in a command shell on a terminal. Something like
tcsh on xterm, for example. I have a program which does *something*.
Let's say it counts down from 10. How do I print a value, and then
erase that value, replacing it with another value? Say I had something
like '10' that appears, then wait a second, then the 10 is replaced by
'9'... '8'.. and so forth.
import time
for t in range(10,0, -1):
print "%s \x0D" %t,
time.sleep(1)
print # get to next line
print "Done!"
The magic is \0x0D, which resets to the front of the line; and the
trailing comma, which suppresses starting the next print on a new line.
