Want faster number-crunching in Python? You can speed up your existing Python code with the Numba JIT, often with only one instruction.

Intel highlights how to achieve high levels of parallelism in large scale Python applications using the Intel Distribution for Python with Numba.

A number of scientific packages for Python, such as Scikit-learn, draw on Cython features like this to keep operations lean and fast. Numba Numba combines two of the previous approaches.
