What tool is primarily used to automatically translate Python code into "C" code?

Cython is primarily used to convert Python code into C code. This is particularly beneficial because it allows for the optimization of Python code, enhancing its execution speed by compiling it to C, which can be significantly faster than interpreted Python. Cython achieves this by translating Python syntax into equivalent C code, allowing developers to write Python-like code while providing the ability to utilize C-level performance.

Cython not only facilitates the translation of Python code into C but also enables the use of C libraries and functions directly within Python applications, making it a powerful tool for performance optimization and extension of Python with C modules.
