Python threading comparison

2021-06-22 Thread Dan Stromberg
I put together a little python runtime comparison, with an embarallel, cpu-heavy threading microbenchmark. It turns out that the performance-oriented Python implementations, Pypy3 and Nuitka3, are both poor at threading, as is CPython of course. On the plus side for CPython, adding cpu-heavy thre

Optimizing Small Python Code

Hi There! this is a small python code executed in 61 steps for n in range(1, 7): print (n) for x in range(0, n): print(" ", x) can this code be more optimised? -- https://mail.python.org/mailman/listinfo/python-list

I had a similar question, Greg. Optimized for what, indeed. Some might suggest removing a VISIBLE loop is an optimization and some might not. First you need to look at what your code does. It is fairly primitive. Here is a two-line version but is it simpler: for n in range(1, 7): print (n,
