- It is true that C code usually runs 10 to 100 times faster than Python code if you measure only the execution time. However if you also include the development time Python often beats C. For many projects the development time is far more critical than the run time performance.

Jan 23, 2017 · It's possible that Jython and IronPython are much faster than CPython as well as they are backed by heavily optimized virtual machines (JVM and .NET CLR). One thing that will arguably leave Python slower however, is that it's dynamically typed, and there is tons of lookup for each attribute access.

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...
Aug 22, 2015 · You could write a compiler in a language like Python or Ruby, whose most common implementations are very slow, and that compiler could output highly optimized machine code capable of outperforming C. The compiler itself would take a long time to run, because its code is written in a slow language.
Feb 4, 2011 · The truth is: PyPy is 35% faster than the C code (using C as the baseline), because it completes in 65% of the time required by the C version. The C code takes 50% more time to execute (is slower by 50%, 1.5x slower) than the PyPy code (using PyPy as the baseline).
Sep 19, 2022 · Based on different benchmarks done by the PyPy team it seems that it is 4.7X faster than CPython (https://speed.pypy.org/). The crazy thing about it is that you don’t need to rewrite the...
Apr 18, 2021 · Although C remains the master of speed in general, PyPy can beat C in some cases. “If you want your code to magically run faster, you should probably just use PyPy.” — Guido van Rossum (creator of Python) Source: youtu.be/2wDvzy6Hgxg?t=1012

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
