Python's print function that flushes the buffer when it's called? [duplicate]

Question

I have the following code to flushing out the output buffer.

print('return 1')
sys.stdout.flush()

Can I set up the print function so that it automatically flushes the buffer when it's called?

Hm, goofed up my link, should have been: unbuffered stdout in python — eldarerathis

You can start python in unbuffered mode using the -u flag, e.g.

python -u script.py

or

#!/usr/bin/env python -u

as "shebang" header for your script.
