   Sep 23, 2013 · They claim it is 6.3 times faster than the CPython interpreter on their site. Whenever we talk about dynamic languages like Python, speed is one of the top issues. To solve this, they say PyPy is 6.3 times faster. The second issue is parallelism, the infamous Global Interpreter Lock (GIL). For this, PyPy says it can give GIL-less Python.

   Shell. $ pypy3 script.py. The result is 999800010000 It took 0.22 seconds to compute. In this small synthetic benchmark, PyPy is roughly 94 times as fast as Python! For more serious benchmarks, you can take a look at the PyPy Speed Center, where the developers run nightly benchmarks with different executables.

   PyPy (/ ˈ p aɪ p aɪ /) is an implementation of the Python programming language. [2] PyPy often runs faster than the standard implementation CPython because PyPy uses a just-in-time compiler. [3] Most Python code runs well on PyPy except for code that depends on CPython extensions, which either does not work or incurs some overhead when run ...

   3 days ago · Yes, PyPy has a GIL. Removing the GIL is very hard. On top of CPython, you have two problems: (1) GC, in this case reference counting; (2) the whole Python language. For PyPy, the hard issue is (2): by that I mean issues like what occurs if a mutable object is changed from one thread and read from another concurrently.

   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.

   What is the difference between CPython and PyPy?

   • Whereas CPython compiles Python to intermediate bytecode that is then interpreted by a virtual machine, PyPy uses just-in-time (JIT) compilation to translate Python code into machine-native assembly language. Depending on the task being performed, the performance gains can be dramatic.

   Is PyPy a compiler?

   • It compiles Python code, but it isn’t a compiler for Python code. Because of the inherent dynamism of Python, it’s impossible to compile Python into a standalone binary and reuse it. PyPy is a runtime interpreter that is faster than a fully interpreted language, but it’s slower than a fully compiled language such as C.

   Oct 10, 2024 · PyPy is a Python implementation similar to CPython that is both compliant and fast. “Compliant” means that PyPy is compatible with CPython, as you can use nearly all CPython syntax in PyPy. There are some compatibility differences, as mentioned here. The most powerful advantage of PyPy is its speed. PyPy is much faster than CPython; we’ll ...
