Hello,
Weird issue I've found on Windows images in Azure Devops Pipelines and
Github actions. Printing Unicode characters fails on these images because,
for some reason, the encoding is mapped to cp1252. What is particularly
weird about the code page being set to 1252 is that if you execute "chcp"
Consider the following code ran in Powershell or cmd.exe:
$ python -c "print('└')"
└
$ python -c "print('└')" > test_file.txt
Traceback (most recent call last):
File "", line 1, in
File "C:\Program Files\Python38\lib\encodings\cp1252.py", line 19, in encode
return codecs.charmap_encode(i

Thank you for your replies - checking the sys.stdout.buf

Hello,
It seems that I can mutate a deque while iterating over it if I
assign to an index, but not if I append to it. Is this the intended
behaviour? It seems a bit inconsistent. Cheers.

I have found myself wanting to import module and provide arguments to them.
There's two main reason I could think of for this. First is to prevent a
circular import, though most of circular imports can be prevented by changing
the design. The second reason is to invert dependencies between two m
First off, thanks for the answer. I don't see the cached module as a problem
here. If you provide arguments to a module, the goal is "most likely" to
alter/parameterize the behavior of the first import. Now, I agree that behavior
becomes unpredictable because passing different parameters on subs
I'm trying to run a shell command but the stdout is empty:

capture_output=True)

That works, thanks.
