I have written a small backup program, that uses ftplib to make
remote backups. However recentely the program starts to regularly
raise IndexErrors, as far as I can see the problem is in socket.py
Can anyone shed some light?
This is the traceback:

Often the actual syntax error in your code is in one of the lines preceding
the one that Python is complaining

I started from this recipe:

made it more to my liking and turned it into a module.
Howdy all,
How should a program generate a unique filesystem path and *not* create
the filesystem entry?
The ‘tempfile.mktemp’ function is strongly deprecated, and rightly so
https://docs.python.org/3/library/tempfile.html#tempfile.mktemp>
because it leaves the program vulnerable to insecure file

The Python documentation suggests that it should not.

Could you use tempfile.TemporaryDirectory and then just use a consistent
name within that directory.

On the PSF-Community list, a Python user points out that LIGO uses
Python, with numpy and IPython, extensively. He linked to
https://losc.ligo.org/s/events/GW150914/GW150914_tutorial.html
which explains, with code, how the gravity wave signal was pulled out of
the (publicly available) raw data.

Just use a regular dict and define __missing__:

return "We gotcha key %r right here!" % key

Hi all
Using asyncio, there are times when I want to execute a coroutine which is
time-consuming. I do not need the result immediately, and I do not want to
block the current task, so I want to run it in the background.
run_in_executor() can run an arbitrary function in the background, but a

You can't run code "in the background" using asyncio. Corout

Threads in Python don't get you parallelism either, of course.
I haven't used async/await yet and it's looking painful.
