There is no real reason to do this. `str.format()` is the new shiny
thing you should be using all the time. Also, '%' is BINARY_MODULO
(where did you even get that name from?) if and only if you have two
numbers, and it performs the modulo division (eg. 27 % 5 = 2)

This will make your code unportable and useless, depending on one
patch you made. Please don’t do that. Instead,

In Python? Tough luck, every int is signed. And it isn’t just a
sledgehammer, it’s something worse. Just do that:
>>> sys.stdout.write('Number = {:,.0f}\n'.format(x))
Much more peaceful.
You can also do a print, like everyone sane would. Where did you
learn Python from? “Python Worst Practice for Dummies”?
