It is printed into "nohup.out", but "nohup.out" is buffered.
You will see it only when the buffer is full or explicitely flushed.

Add:

	from sys import stdout
	stdout.flush()

after your print statement and you will see the output
immediately in "nohup.out".

Even Windows supports redirection of "stdout".
Apparently, it stole (and that has been good!) the Unix syntax: "> xxx".
We all like that our software incorporates good ideas from others,
don't we?
