Python in production engineering

Python aficionados are often surprised to learn that Python has long been the language most commonly used by production engineers at Facebook and is the third most popular language at Facebook, behind Hack (our in-house dialect of PHP) and C++. Our engineers build and maintain thousands of Python libraries and binaries deployed across our entire infrastructure.

Every day, dozens of Facebook engineers commit code to Python utilities and services with a wide variety of purposes including binary distribution, hardware imaging, operational automation, and infrastructure management.
