Addendum:
I was working on a program where i needed to split a path into dirname,
corename, and suffix.
I came to this page and took me a while to understand what split() is
about. There are other path related functions splitext(), splitdrive(),
basename(), dirname(). User has to scan the whole page and read
painfully each one to fully understand how to choose and use them for
the task at hand.
As i have explained before (see references at bottom), documentation
should be organized oriented towards programer's tasks, not
alphabetically, compiler view, or computer sciency scheme. On this
os.path module, split(), splittext(), dirname(), basename() should all
be under one section. This way, their usefulness and each's fitness
becomes clearer, and also easier to document as a collective. Other
functions that test files or get info about files should be together.
Don't be afraid that there are functions that doesn't fit into some
“classification”. For exapmle, the walk() and
supports_unicode_filenames() can be lumped at the bottom as Other. The
need to present materials in some aloof, computer sciency, academic,
precision pretensions way is a major usability problem in the Python
doc.
(the OpenSourcers's need to present materials that way is a backlash of
the willful juvenile sloppiness of unix/perl community. However, they
being the same crowd without significant critical thinking and writing
skills, cannot do better by hiding in formality.)
Also, at the top we see:
Warning: On Windows, many of these functions do not properly
support UNC pathnames. splitunc() and ismount() do handle them
correctly.
As indicated before, this is a exhibition of tech geeking and
jargonizing. If this warning is necessary, place it at the bottom of
the page as a footnote. Also, spell out UNC, and provide a link to its
proper spec.
Tech geekers are very pretentious of tech matters. They are afraid, as
if spelling out UNC would make them unprofessional, that their peers
would deem them inferior. There are a myriad of techincal standards
that any programer could only be familiar with a fraction, confined to
his area of expertise. Standards and its acronyms come and go , and
each with varying degree of precision, actual revelance, and they are
intermingled with de facto “standards” in the commercial world that
may not even have official names. The tech geekers are clouded by their
narrow knowledge. The purpose of documentation is not some cold
academic presentation. Vast majority who came to use os.path wouldn't
know what UNC is. Spell things out when in doubt.
UNC here, isn't really a significant “standard”. This warning
should be left out.
