Note: Numba [1] 0.34.0 is in unstable now. Although the package still needs a couple of fixes to go into testing, on amd64 and some other archs it appears to run properly. Nutshell: Numba is an on-the-fly/just-in-time (JIT) machine code compiler for Python. Just decorate certain computation intensive functions with "@jit" to speed them up and execute the script, that's basically it [2]. It's pretty straightforward to use. Under the hood, LLVM resp. llvmlite [3] is used to perform the compilation into native machine code. /usr/share/doc/numba-doc/examples contains a couple of examples: $ ./bubblesort.py == Test Pure-Python == [0 1 2 3 4 5 6 7] == Test Numba == [0 1 2 3 4 5 6 7] Python 0.257357192039 Numba 0.000370597839355 Speedup 694.437918168 x [Intel Core i5-6200U] Numba especially integrates with the Python scientific stack and supports accelerated Numpy array computation on CUDA/GPU devices, I'll write more about that on Planet Debian, soon.
