Basic Pybind Usage

This project contains C++ code using Pybind11 to expose a simple loop function to Python. The goal is to compare the performance of different implementations of the loop in Python and C++.

Files

1. forloop.cpp: C++ source code that defines a simple loop function.
2. forloop_w_default.py: Python script that demonstrates loop function without Pybind11.
3. forloop_w_pybind.py: Python script that uses the loop function exposed through Pybind11.
4. so.cpp: Pybind11 module source code that binds the C++ loop function for use in Python.
5. CMakeLists.txt: CMake file for building the project.
6. Images: Folder containing images illustrating the testing results for the loop function.

This project has the following dependencies:

• Pybind11: A lightweight header-only library for creating Python bindings for C++ code.

Installing Dependencies

Use the provided shell script to install the dependencies. Ensure that you have the necessary build tools, such as CMake and a C++ compiler, installed on your system before running the script.

Build Instructions

Make sure you have CMake installed.

mkdir build
cd build
cmake ..
make

Running Tests
