1. • • For General Use: CPython is often the best choice due to its compatibility and the vast ecosystem of libraries and tools. For Performance-Sensitive Applications: PyPy can be a better choice if your application can benefit from JIT compilation, especially if it is long-running and computationally intensive.

   Sep 23, 2013 · Long-term evidence is showing that PyPy runs certain Python codes slower than CPython and this drawback seems to be rooted very deeply in PyPy. Secondly, the current version of PyPy consumes much more memory than CPython in a rather large set of cases.

   This page documents the few differences and incompatibilities between the PyPy Python interpreter and CPython. Some of these differences are “by design”, since we think that there are cases in which the behaviour of CPython is buggy, and we do not want to copy bugs.

   Mar 16, 2024 · Definition: PyPy is an alternative implementation of Python, featuring a Just-In-Time (JIT) compiler designed to execute Python code faster than CPython. Performance: PyPy can significantly outperform CPython on long-running programs due to its JIT compiler, which optimizes frequently executed code.

   Does PyPy run on CPython?

   • PyPy is written in Restricted Python. It does not run on top of the CPython interpreter, as far as I know. Restricted Python is a subset of the Python language. AFAIK, the PyPy interpreter is compiled to machine code, so when installed it does not utilize a python interpreter at runtime.

   Is iron Python better than CPython?

   • IronPython lets you run Python on the Microsoft CLR. And PyPy, being implemented in (a subset of) Python, lets you run Python code faster than CPython, which rightly should blow your mind. :-)

   How fast is PyPy compared to CPython?

   • On the (geometric) average, PyPy speeds up Python by about 4.7 times over Python 3.7, with some tasks accelerated 50 times or more. While JIT optimizations of certain kinds are being added to new versions of the CPython interpreter, they aren’t of the same scope and power as what PyPy does right now.

   • Long-term evidence is showing that PyPy runs certain Python codes slower than CPython and this drawback seems to be rooted very deeply in PyPy. Secondly, the current version of PyPy consumes much more memory than CPython in a rather large set of cases. So PyPy didn't solve the memory consumption problem yet.

But there are others, oh, so many others: Pypy, Python written in Python. Stackless Python, the Eve Online secret sauce. Jython, running on the JVM. IronPython, running on .Net. MicroPython, for micro-controllers.
