why python is used much more in DS instead of a more efficient language like Java or Rust?

• NumPy

  272 26,231 10.0 Python

  The fundamental package for scientific computing with Python.

  

  A lot of Data Science work in Python is based on Numpy. If you look at the GitHub repo, 30% of the code is C: https://github.com/numpy/numpy

• tensorflow

  221 182,173 10.0 C++

  An Open Source Machine Learning Framework for Everyone

  

  If you want to look at machine learning, 60% of Tensorflow is in C++: https://github.com/tensorflow/tensorflow

• InfluxDB

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• examples

  142 7,728 6.2 Jupyter Notebook

  TensorFlow examples (by tensorflow)

  

  Numba plugs into LLVM JIT API, Tensorflow is written in C++, PyTorch core is C++, NumPy integrates BLAS libraries written in C and Fortran.

• Pytorch

  334 77,544 10.0 Python

  Tensors and Dynamic neural networks in Python with strong GPU acceleration

  

  Numba plugs into LLVM JIT API, Tensorflow is written in C++, PyTorch core is C++, NumPy integrates BLAS libraries written in C and Fortran.

• Numba

  124 9,404 9.9 Python

  NumPy aware dynamic Python compiler using LLVM

• bjoern

  1 2,976 0.0 C

  A screamingly fast Python 2/3 WSGI server written in C.

  So, the thing that's handling lower-level stuff is separate from the application server. So, you can pick a performant server, like Bjoern to host a WSGI application, like Django. Bjoern is 60% C. Just like Numpy and Tensorflow that I mentioned before.

• WorkOS

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• fastapi

  462 70,541 9.7 Python

  FastAPI framework, high performance, easy to learn, fast to code, ready for production

  For an end-to-end solution, in my experience FastAPI is more than quick enough for APIs that I am writing. If I need an actual website (rendered HTML) then I'd typically just grab Django because it's easy.
