Many well-known Linux distributions already use Python in their key tools. Red Hat's Anaconda installer, and Gentoo's Portage package manager are two examples. Ubuntu (the top distribution for the last 12 months, according to DistroWatch) "... prefers the community to contribute work in Python."
"Among the high level languages, Python seemed to be the best choice, since we already use it in many places like package build scripts, package manager, control panel modules, and installer program YALI. Python has small and has clean source codes. Standard library is full of useful modules. Learning curve is easy, most of the developers in our team picked up the language in a few days without prior experience."
So why aren't you using Python? (Don't tell me, you are ...)
