Python

The Python programming language is widely used by companies around the world to build web apps, analyze data, automate operations via DevOps and create reliable, scalable enterprise applications.

There is also a fantastic list of organizations using Python on the Python.org wiki as well as a detailed write-up of several top Python-powered companies on Real Python’s blog.

Many companies do not even realize they are using Python across their organizations. For example, if a company is a “Java-only shop” but they use IBM WebSphere as a web application server then they have to use Python to script the server’s configuration! Python has a habit of getting in everywhere regardless of whether the usage is intentional.
