Hi
How do I create a valid file name and directory with pathlib?
When I create it using PurePosixPath I end up with an OSError due to
an
obvously invlaid path being created.
You're on Windows. The rules for POSIX paths don't apply to your file
system, and...
OSError: [Errno 22] Invalid argument:
'C:\\Users\\Sayth\\Projects\\results/Warwick
Farm2017-09-06T00:00:00.json'
... the colon is invalid on Windows file systems. You'll have to
replace those with something else.
I haven't followed closely, so this may well not be an issue here, but
the
colon is valid on a Windows file system; it introduces an alternate
data
stream:

So this is perfectly valid on Windows:
with open("temp.txt:abc", "w") as f:
f.write("abc")
Have you tested that?
Yes. I ran it before posting.
My understanding of the document you linked to
is that the colon still has special meaning, and thus you can't use it
in arbitrary file names.
In fact its presence in that filename creates a (usually hidden) data
stream piggybacked onto that file which has the name "abc" into which
the data is written.
So, following on, the follow works:
assert open("temp.txt:abc").read() == "abc"
