I'd like to have an option to force the path separator for the
"os.path.join()" method.
E.g. if I run the script on Windows, but I generate, say, an URL, I'd
find it convenient
to use the same method, but with an explicit flag to "join" with the
forward slash (because URLs use it).
Currently I simply use an f-string to combine a path, like e.g.:
path = f"{root}/{dir}"
but it will insert extra "/" if there if "root" already has "/" on the end.
But the "join" method will not, which is a pro for the method vs
"manual" string construct.
I know there is the "pathlib" module with all conversion methods, but
it's overkill for many
tasks. So I'd rather like to have an option to write for example:
path = os.path.join (root, dir, sep = "posix")
So that it joins with the forward slash even if run on Windows.
Also it seems that e.g. "os.path.split()" already supports both
separators, so I think this addition won't bring inconsistency into
the module and its usage.
