MongoDB uses Python extensively, both as a main programming language for its internal development and as a tool for scripts and one-off jobs. The company's own projects, such as PyMODM, also rely heavily on Python. MongoDB engineers and developers often use Python to interact with the database, and even the company's documentation team utilizes it. In fact, the MongoDB University website is built using Python, serving as an example of how MongoDB products can be used in-house. The company sponsors Python events and encourages its engineers to attend and speak at these events, further demonstrating its commitment to the language.
