Now, a lot of people are unaware of the connection between Python and this browser's success. 

Initially, Mozilla Firefox was developed using PHP+CakePHP. But as the business grew, those languages were unable to process the millions of queries that were made every month. Thus, Mozilla was switched to Python+Django by the developers. 

The organization now uses Python to carry out tasks like test harnesses, continuous integration configuration, command-line tooling, and system construction. 

16. Amazon

Well, everyone has heard the story of this garage startup. When the internet was just starting, a guy named Jeff Bezos had this idea: 'What if people could buy books online?' That's how the online bookstore Amazon was founded in 1994.

Today, Amazon has grown quickly and has become a household name. It offers lakhs of products with categories ranging from fashion, electronics, and homewares to furniture, personal care, and sporting goods. Amazon.com is now recognized as one of the Big Five tech companies along with Microsoft, Apple, Meta, and Alphabet.

But what most people don’t know is that the recommendation engine employed on its digital platform is built using Python. Thanks to Python's scalability, it stands out as one of the premier technologies for extensive data analysis.
