In python 2.7, the print function will not allow an end parameter, and print 'Update %d\r' will also print a newline character.

Here is the same example @elethan gave for python2.7. Note it uses the sys.stdout output stream:

import sys
import time
output_stream = sys.stdout

for i in xrange(10):
    output_stream.write('Update %s\r' % i)
    output_stream.flush()
    time.sleep(5)
# Optionally add a newline if you want to keep the last update.
output_stream.write('\n')
