Easiest way?
http://en.wikipedia.org/wiki/Carriage_return


print "I hate carriage return\rI love",

Use the "," to avoid the python automatic newline.

Or if you already jumped into python3:


print("I hate carriage return\rI love", end="")

#!/usr/bin/env python
from time import sleep
import sys
for x in range(10):
print '\r%s'%x,
sys.stdout.flush()
sleep(1)

You'll need to flush the output too...

The '\r' tip is a good one. Just for information, if you want a full control of your terminal display you can use the curses (http://docs.python.org/howto/curses.html) module.

Pair it with string multiplication to create a loading bar:


#!/usr/bin/env python
from time import sleep
import sys

for x in range(100):
print '\rDownloading: %s (%d%%)' % ("|"*(x/2), x),
sys.stdout.flush()
sleep(0.1)

(Remember that "hello "*3 = "hello hello hello ")
