Cppyy
Cppyy is a Python-C++ interoperability tool that allows Python code to call C++ code directly, without the need for manual bindings or wrappers. It uses the Cling C++ interpreter and LLVM to parse C++ headers at runtime, generating Python bindings on-the-fly. This enables seamless integration of C++ libraries into Python applications, improving performance and leveraging existing C++ codebases.
Developers should use Cppyy when they need to integrate high-performance C++ libraries into Python projects, such as for scientific computing, data analysis, or machine learning, where Python's ease of use is desired but C++ speed is critical. It is particularly useful in scenarios like prototyping with legacy C++ code, building hybrid applications, or when avoiding the complexity of tools like SWIG or Boost.Python is preferred.
