Example Folders

random4/

from xkcd-221:

Implementation of a Python module contains a function that returns 4, implemented in:

• Python3.7+
• Cython
• C (#include <Python.h>)
• Rust (PyO3 crate)
• Rust (rust-cpython crate)

This example shows how to call a foreign function in other language from Python and the benchmarks shows the round trip time.

run benchmarks:

$ make test

fib/

Implementation of a Python module contains a function to sum the even fib numbers under the given num, implemented in:

• Python
• Cython
• C (#include <Python.h>)
• Rust (PyO3 crate)
• Rust (rust-cpython crate)

This example shows a heavy numeric calculation on a foreign language called from python.

run benchmarks:

$ make test
