Python isn&#x27;t used for much ML in the field from my experience. It is heavily used for teaching and learning about ML - but for actual production ML, I&#x27;ve seen mostly compiled languages. The main reason is that ML is highly parallelizable and Python isn&#x27;t terribly good at that. Plus you need to crunch large datasets and speed becomes important.<p>So, respectfully, lots of people use languages other than Python for ML, and I doubt if Python is even the largest deploy base of ML.
