Do I absolutely need to master Python before starting Deep Learning?

All answers to this question.

While you technically can use other languages, Python is the industry standard for a reason. The entire ecosystem of Deep Learning—libraries like NumPy, Pandas, Scikit-learn, and the big ones like PyTorch and TensorFlow—is built around Python. It’s used as a "wrapper" for the high-performance C++ code that runs in the background. If you want to get hired as a Deep Learning engineer, mastering Python is essentially a hard requirement because that’s what the teams use for prototyping, research, and deployment. Your C++ knowledge will be a huge bonus for optimizing models, though!

If Python is just a wrapper, does that mean performance suffers compared to writing the entire neural network in a lower-level language like C++ or Rust?

• Kevin, not really. Because the heavy lifting (matrix multiplications) is actually executed in C++ and CUDA (on GPUs), Python just acts as the coordinator. You get the ease of Python's syntax with the speed of C++. That's why the combination is so dominant; you aren't sacrificing performance for developer speed.

Yes, Python is mandatory. Its massive community and pre-built libraries make it impossible to ignore if you want to be productive in the AI space.

• True, Sandra. Trying to do Deep Learning without Python is like trying to swim upstream; you're just making it unnecessarily difficult for yourself and your team.
