PythoC is a Domain-Specific Language compiler enabling developers to write C programs using standard Python syntax. It compiles a statically-typed subset of Python directly to native machine code via LLVM IR, producing standalone executables without requiring Python or a garbage collector. This offers C-equivalent runtime with Python's cleaner syntax, including low-level control features like manual memory management and explicit deallocation. Standalone native executables are a core advantage, differentiating it from tools like Cython which focus on Python extensions.

The library leverages Python's metaprogramming capabilities for compile-time code generation, similar to C++ templates but driven by pure Python logic. This approach allows for highly flexible compile-time specialization.
