   Sep 23, 2013 · "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 rarely worse. 4. Many "scripts" are just glue code - making the interpreter faster won't improve overall runtimes in that case. 5.

   Note that if you have a long chain of objects, each with a reference to the next one, and each with a __del__, PyPy’s GC will perform badly. On the bright side, in most other cases, benchmarks have shown that PyPy’s GCs perform much better than CPython’s. Another difference is that if you add a __del__ to an existing class it will not be ...

   Efficient in this sense means striking a balance between development time of the interpreter and performance of code being run by the interpreter. PyPy can run faster than cpython because the pypy JiT compiler compiles to native code for a specific processor. CPython does not compile to native code.

   Mar 16, 2024 · Choosing Between CPython and PyPy. 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.

   Aug 19, 2021 · To overcome the slowness of python, developers have created multiple different compilers to compile python either to other programming languages, to machine code, or to do Just in Time compilation. Some of the popular python compilers include Cython, Nuitka, Brython, PyPy, and Iron Python.

   Is PyPy faster than CPython?

   • 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.

   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?

   • The above is true both in CPython and in PyPy. Differences can occur about whether a built-in function or method will call an overridden method of another object than self. In PyPy, they are often called in cases where CPython would not. Two examples: Consider the following snippet of code:

   What is the difference between Python and Cython?

   • Cython vs. Python debate gets to the next level because of speed gains too. It is also worth noting that the speed gains from Cython programs are up to 15x compared to the raw python code interpreted using CPython (the default interpreter). What is PyPy? PyPy works on the Just in Time compilation principle.

   Why do some programs still depend on CPython?

   • Some programs may still depend on CPython's unique features that are absent in PyPy such as C bindings, C implementations of Python object&methods, or the incremental nature of CPython's garbage collector. This answer does not cite any benchmarks or provide references.

   • 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. upgraded with new features, language developers upgrade the CPython version as well and include it in the distribution that you download to set up Python on your machine.

   Dec 12, 2021 · PyPy is a Python implementation written in Python (specifically RPython) and is a replacement for CPython. PyPy's main utility is that it is really fast, in fact, it claims to be almost 5x faster than CPython. However, PyPy can run most Python code except for when the code depends on CPython extensions which results in either inability to run ...
