import re num = 123456789
print ','.join(re.findall("\d{3}", str(num))) output: 123,456,789 ----- Original Message ----- From: [EMAIL PROTECTED] To: tutor@python.org Date: Fri, 21 Mar 2008 21:49:18 -0700 Subject: [Tutor] Even More Converter! It works perfectly, so I am sure my question will not be hard to answer. When Python gives me the answer to my conversion, is there a way to create it so every 3 numbers a comma is inserted? Such as: 1 mile is 5,280 feet. Instead of 1 mile is 5280 feet. Yes a simple thing, but something which I believe will make it look better. Also is there a way to make this so I don't have to go through every individual line of code and add *insert comma* or something to it, simply at the top like how the Unit Menu is placed only once there, and yet applies to the whole document.
