CPython - AshokBhat/notes GitHub Wiki

About

• Reference implementation of the Python programming language
• Default and most widely-used implementation
• Interpreter + Compiler - Compiles Python code into bytecode before interpreting it

CPython limitations

• No performance optimizations by design
  • No native JIT (just-in-time) compiler
  • No accelerated math libraries
  • No third-party additions for the sake of performance
• Only a baseline set of tools for working with Python
  • pip installs from PyPI
  • Won’t install any dependencies that packages might have outside of PyPI

Alternatives

Other Production-quality Python implementations

• Jython, written in Java for the Java virtual machine (JVM)
• PyPy, written in RPython and translated into C
• IronPython, written in C# for the Common Language Infrastructure
