Maybe you compiled Python 2.7 by hand, David? It happened to me when I tried to compile Python without zlib headers installed on my OS. Don't know how it can be done on Windows. -- https://mail.python.org/mailman/listinfo/python-list

Re: Long running process - how to speed up?

Hi, How I understand your script starts another script and should wait until second one completes its job. Right? If so you have several options depend on how your first script is written. If your script is async then ... there is good asyncio option proc = await asyncio.create_subprocess_sh

Long running process - how to speed up?

I have a cvs file of 932956 row and have to have time.sleep in a Python script. It takes a long time to process. How can I speed up the processing? Can I do multi-processing? Regards, David -- https://mail.python.org/mailman/listinfo/python-list
