nested loops in Python

Why nested loops are so slow in Python? Is it because new contexts are created? For more details, see http://stackoverflow.com/questions/26611043/numpy-vs-cython-nested-loop-so-slow http://stackoverflow.com/questions/39371021/efficient-loop-over-numpy-array Thanks! -- https://mail.python.org/mail

Yes, of course I did not write posixmodule.c, it is a part of the python 2.7 distribution and I have no idea how to not use it and I believe I have no control over it, unless I go inside of python distribution and modify it. Is this what you are recommending? On 09/07/2016 05:36 PM, Ben Finne

In fact I tried issuing commands manually, but they did not give me any hint more than I already had. In python 2.6 this all works with the same libc, of course (because I tried to compile on the same machine). Thanks anyway. On 09/08/2016 01:22 AM, dieter wrote: "Alexander N. Moibenko"
