在OS X上的python中，如何打印光标并将光标留在同一行的开头？

Question

I would like my program to display some status messages as it runs, each one overwriting the previous. In Windows, I have been using the following to print a message and leave the cursor at the beginning of the line ready for the next message:

print message, '\r',

On OS X, however, this does not work - the cursor is at the beginning of the next line. It was suggested that I change \\r to \\x1b[0G , but this has the same effect.

How can I leave the cursor at the beginning of the current line?

Answer 1

This seems to do it in a Terminal window:

import time
import sys

print 'Hello\r',
sys.stdout.flush()
time.sleep(3)
print 'There\r',
sys.stdout.flush()
time.sleep(3)

Answer 2

Sorry for the inconvenience - turns out \\r works fine. The issue was caused by message being longer than a single line.

This never happened on Windows because I have a Screen Buffer Width far in excess of my Window Width , whereas on OS X it seems the two are always the same.
