If we're not counting PyPy, and we're not counting Cython, and we're not counting the ease of writing CPU-bound code in C or C++[1] while leaving the rest of your application in Python (e.g., like Numpy and other libraries do), then we're left with: Releases like Python 3.6[2], where lots of little optimizations are made, give Python a performance growing edge on Ruby. 1. https://docs.python.org/2/extending/extending.html https://docs.python.org/2/extending/extending.html 2. https://docs.python.org/3.6/whatsnew/3.6.html https://docs.python.org/3.6/whatsnew/3.6.html
