Sep 23, 2013 · @tommy.carstensen This isn't really a good place to go in depth, but I'll try. 1. This was a lot more true when I wrote it than it is now. 2. "Scripts" are oft IO-heavy. PyPy's IO is still often slower than CPython's - it used to be significantly slower. 3. PyPy used to be slower than CPython at handling strings - now it's often better and ...
Yes, we used PyPy for years, until a bit over a year ago when CPython 3.11 was released. In 3.11 the difference in execution speed between PyPy and CPython was so negligible for our software, that we switched back to CPython. 3.12 gave another nice performance boost. We do a lot of CPU bound NetworkX graph calculations.
If you're just getting started there is no reason you must start with CPython, and migrating from PyPy to CPython should be quite painless as long as you migrate to a similar version (you can't go from PyPy to CPython 3.2, but you probably can migrate to CPython 2.7) There isn't necessarily a time to say goodbye to CPython.

Talking about CPython, it is the default implementation of Python specifications. It comes with the python distribution itself and interprets the python programs for the machine. Given that it is the default implementation of Python, whenever Python is upgraded with new features, language developers upgrade the CPython version as well and include i...
Cython is a separate compiler that can understand both Python and C specifications. It is more like a superset of Python compiler and allows you to work with Python and C together in a single project. How does this help? Alright, so, Cython compiles the hybrid python and C code into a very efficient C program which in turn can be compiled to the ma...
PyPy works on the Just in Timecompilation principle. Like interpreters, JIT compilers also pick up the raw code but turns the code into efficient machine code just before the execution. There are a lot of optimization techniques involved in JIT compilers and that makes JIT compilers work much faster than the raw interpreters. PyPy also consumes les...
While there are multiple compilers, they all try to solve different problems and work differently. Looking at the statistics and usage, Cython seems to be the leader in the game and provides the fastest execution speeds, has a great community, good documentation, and is a potential candidate to get included in the default python distribution itself...
PyPy is a fast and capable alternative to CPython. By running your script with it, you can get a major speed improvement without making a single change to your code. But it’s not a silver bullet. It has some limitations, and you’ll need to test your program to see if PyPy can be of help. In this tutorial, you learned: What PyPy is
Sep 19, 2022 · The only thing that needs to be done is to replace CPython with PyPy. It is important to know that PyPy supports most of the tools that are part of the “Python Echosystems”. Examples for that ...

Sep 24, 2022 · If you tried Python before, you were probably running CPython [3]. CPython is the most common implementation of Python VM (Virtual Machine). PyPy [4] is an alternative to CPython. With PyPy, we write our programs in RPython [5], and apply the RPython translation toolchain that generates binary executable. One major advantage of PyPy over ...
