Questions tagged [pythran]

Pythran is a Python-subset-to-C++-transcompiler, geared towards speeding up scientific programs by using available processor-level parallelism.

Pythran transcompiles Python modules written in a subset of the Python language and annotated with some interface description to to system-native (C++) code. The result is a new Python module wrapping the generated C++ code, with the same interface as the original module.

The aim of this conversion is a runtime speedup due to

  • system-native instead of interpreted/JiT-compiled code
  • usage of multiple cores
  • usage of units

Pythran is geared towards scientific programs.
