Pythran: Python at C++ speed !. Case Study: Simulated Annealing applied… |  by Olivier Borderies | Medium

Have you ever faced this awkward situation: you wrote a Python script for scientific computing, it works great, but it runs as slow as a snail?

The CPU churns for ages, and you’re left wondering, “Is there any way to make it zoom?” Don’t worry, today I’m introducing a “black tech” tool—Pythran, which can instantly transform your Python scientific computing into C++ modules!

What is Pythran?

Pythran is an Ahead-of-Time (AOT) compiler designed for scientific computing scenarios.

In simple terms, you keep writing familiar Python code, add a few annotations, and it automatically compiles critical modules into C++ code, then into native binaries.

The import and usage remain almost unchanged, yet it unleashes extreme performance on multi-core and SIMD units.
