What is a compiled Python file?

pyc files are created by the Python interpreter when a . py file is imported. They contain the “compiled bytecode” of the imported module/program so that the “translation” from source code to bytecode (which only needs to be done once) can be skipped on subsequent imports if the . pyc is newer than the corresponding .

What is Cython in Python?

Cython is a programming language that aims to be a superset of the Python programming language, designed to give C-like performance with code that is written mostly in Python with optional additional C-inspired syntax. Cython is a compiled language that is typically used to generate CPython extension modules.

The PyPy implementation is 16 times faster than the CPython implementation and about 3 times slower than the Cython implementation. This is fascinating since PyPy is running the exact same pure Python code as the CPython implementation – it shows the power of PyPy’s JIT compiler.
