   On average, PyPy is 4.4 times faster than CPython 3.7. We currently support python 3.10 and 2.7. PyPy (with JIT) benchmark times normalized to CPython. Smaller is better. Based on the geometric average of all benchmarks "... we are avid fans of PyPy and commensurately thankful for the great work by the PyPy team over the years.

   The main difference in pure-python code that is not going to be fixed is that PyPy does not support refcounting semantics for "automatically" releasing state when an object's __del__ is called. The following code won't fill the file immediately, but only after a certain period of time, when the GC does a collection and flushes the output, since the file is only closed when the __del__ method ...

   Is PyPy compatible with CPython?

   • PyPy's meta-tracing toolchain is called RPython. PyPy does not have full compatibility with more recent versions of the CPython ecosystem. While it claims compatibility with Python 2.7, 3.7, 3.8 and 3.9 ("a drop-in replacement for CPython"), it lacks some of the newer features and syntax in Python 3.10, such as syntax for pattern matching.

   Does PyPy 3 support gmpy2?

   • PyPy has had Python 3 support for a while, but according to this HackerNoon post by Anthony Shaw from April 2nd, 2018, PyPy3 is still several times slower than PyPy (Python 2). For many scientific calculations, particularly matrix calculations, numpy is a better choice (see FAQ: Should I install numpy or numpypy?). Pypy does not support gmpy2.

   Why is PyPy better than CPython?

   • Speed: thanks to its Just-in-Time compiler, Python programs often run faster on PyPy. (What is a JIT compiler?) Memory usage: memory-hungry Python programs (several hundreds of MBs or more) might end up taking less space than they do in CPython. Compatibility: PyPy is highly compatible with existing python code.
