Question about text in Python

[Steve]

Hi,

I've created a Python program that a user enteres one line of text which 
will then create an acronym from that text.

What I want to add to the program is the abilty to rerun this process (where 
the user enteres another line of text) until the user has had enough and 
enters a blank line which would then end the program.

Can anyone help with this?

thanks
