import re
num = 12345678
print ','.join(re.findall("\d{3}", str(num)))


Where is the '78'?

It looks like that solution inserts comma's from left to right
instead of from right to left.

"You assist an evil system most effectively by obeying its
orders and decrees. An evil system never deserves such
allegiance. Allegiance to it means partaking of the evil.
A good person will resist an evil system with his or her
whole soul." [Mahatma Gandhi]
