PyPy is an alternative implementation of the Python programming language built explicitly to address Python’s most notorious bottleneck: execution speed. Unlike the standard Python implementation, CPython, which interprets bytecode line-by-line, PyPy utilizes a Just-In-Time (JIT) compilation system to translate heavily executed parts of code directly into machine-level code at runtime.
This architecture allows PyPy to execute long-running scripts anywhere from 2x to over 10x faster than standard Python. What is Just-In-Time (JIT) Compilation?
Traditional code execution generally falls into two distinct categories:
