Raspberry Pi & Python 2.7 - trying to print to all users

Question

I have a program that runs when the Pi is booted.

The print statements are not displaying on additional terminal sessions.

I can only get the print statements when I kill the auto-booted process and restart the program.

Is there a method to broadcast print messages to all users - like the message displayed then typing 'Halt'?

Thx

You are looking for the wall BSD function.

NAME wall -- write a message to users

SYNOPSIS wall [-g group] [file]

DESCRIPTION The wall utility displays the contents of file or, by default, its standard input, on the terminals of all currently logged in users.
