Multiprocessing "Pool" aborts without any error message or return code? (Python 3.6.4, cygwin 32 bit, Windows Server 2012)
Please refer to: https://docs.python.org/3.6/library/multiprocessing.html the first example program. If I run it on Windows 10 (Python 3.6.4) or Linux Mint 18 (Python 3.5.2), it works as expected.

It looks like the encoding of stdout is not utf-8 in the CGI script. Check it
with
import sys
print(sys.stdout.encoding)
If it's not utf-8, you must force your output to be utf-8, as that is what the
browser expects, because of your Content-type.
You could use:
sys.stdout.buffer.write('ранее предусматривалась смертная
казнь.'.encode('utf-8'))
Or to change stdout into utf-8 encoding:
import codecs
sys.stdout = codecs.getwriter("utf-8")(sys.stdout.detach())
[Note: I haven't tested this]

Sounds like your browser is ignoring the charset. Can you force the
browser to utf-8?
What happens if you create a plain html file with the same content and
send it to your browser?
eg: test.html:
-
Hello, world!
ранее предусматривалась смертная казнь.
-
This really doesn't look like a python issue (again).

I wouldn't even count this as a coding problem, except perhaps for a

[CODE] - Python Newcomer Starting with Coding
Where can I find practical coding examples for real life coding problems? Something like a categorized solution guide? - My current problem: * create a folder * seems to be: os.mkdir(path) * obtain the path of a python package * copy the content of the package folder to the created folder alternatively (which would possibly preserve the file-attributes) * obtain the path of a python package * copy the content of the package folder to the destination folder, whlist giving a new name.

Re: Cheapest pocket device to code python on
. I could actually touch-type on the psion (a genuine [/]pocket computer!) but I was looking forward to eventually writing a key mapper (new key layouts are always an aggravation) . my plans were snipped in the bud however, because I got cheap and tried to sneak around the warranty with a universal ac adaptor; I didn't check the voltage myself with a meter, and found out the hard way that it was putting out twice the expected voltage . apparently a lot of other people were making mistakes like that, because shortly after psion arrived from the uk, they dropped customer service for the usa -- except the corporate acct's, where they could deal with professional IT staff who didn't need their nose wiped !
