In python, is there an easy way to turn humanized text into an integer, and then back to humanized text?
===

Let's say I have a number like this:

**8,741** or **8,741,291**

How can I use python to multiply that number by 2, and then put commas back into it?
I want the python function to return 

**17,482 and 17,482,582**, in a string format.
