Typically, the second positional argument for ``seek()`` is *whence*. That is the POSIX standard name (http://man7.org/linux/man-pages/man3/lseek.3p.html) and the name listed in the documentation for ``io`` module (https://docs.python.org/3/library/io.htmlGH-io.IOBase.seek).
The tutorial for IO is the only location where the second positional argument for ``seek()`` is referred to as *from_what*. I suspect this was created at an early point in Python's history, and was never updated (as this section predates the GitHub repository):
```
$ git grep "from_what"
Doc/tutorial/inputoutput.rst:To change the file object's position, use ``f.seek(offset, from_what)``. The position is computed
Doc/tutorial/inputoutput.rst:the *from_what* argument. A *from_what* value of 0 measures from the beginning
Doc/tutorial/inputoutput.rst:the reference point. *from_what* can be omitted and defaults to 0, using the
```
For consistency, I am suggesting that the tutorial be updated to use the same argument name as the IO documentation and POSIX standard for ``seek()``, particularly since this is the only location where *from_what* is being used.
Note: In the POSIX standard, *whence* is technically the third positional argument, but the first argument *fildes* (file descriptor) is implicit in Python.

This is a restructuring of the datetime documentation to hopefully make
them more user-friendly and approachable to new users without losing any
of the detail.
Changes include:
- Creating dedicated subsections for some concepts such as:
- "Constants"
- "Naive vs Aware"
- "Determining if an Object is Aware"
- Give 'naive vs aware' its own subsection
- Give 'constants' their own subsection
- Overhauling the strftime-strptime section by:
- Breaking it into logical, linkable, and digestable parts
- Adding a high-level comparison table
- Moving the technical detail to bottom: readers come to this
section primarily to remind themselves to things:
- How do I write the format code for X?
- strptime/strftime: which one is which again?
- Touching up fromisoformat + isoformat sections by:
- Revising fromisoformat + isoformat for date, time, and
datetime
- Adding basic examples
- Enforcing consistency about putting formats (i.e. ``HH:MM``)
in double backticks. This was previously done in some places
but not all
- Putting long 'supported formats', on their own line to improve
readability
- Moving the 'seealso' section to the top and add a link to dateutil
Rationale: This doesn't really belong nested under the
'constants' section. Let readers know right away that
datetime is one of several related tools.
- Moving common features of several types into one place:
Previously, each type went out of its way to note separately
that it was hashable and picklable. These can be brought
into one single place that is more prominent.
- Reducing some verbose explanations to improve readability
- Breaking up long paragraphs into digestable chunks
- Displaying longer "equivalent to" examples, as short code blocks
- Using the dot notation for datetime/time classes:
Use :class:`.time` and :class:`.datetime` rather than :class:`time` and
:class:`datetime`; otherwise, the generated links will route to the
respective modules, not classes.
- Rewording the tzinfo class description
The top paragraph should get straight to the point of telling the reader
what subclasses of tzinfo _do_. Previously, that was hidden in a later
paragraph.
- Adding a note on .today() versus .now()
- Rearranging and expanding example blocks, including:
- Moved long, multiline inline examples to standalone examples
- Simplified the example block for timedelta arithmetic:
- Broke the example into two logical sections:
1. normalization/parameter 'merging'
2. timedelta arithmetic
- Reduced the complexity of the some of the examples. Show
reasonable, real-world uses cases that are easy to follow
along with and progres in difficult slightly.
- Broke up the example sections for date and datetime sections by putting
the easy examples first, progressing to more esoteric situations and
breaking it up into logical sections based on what the methods are
doing at a high level.
- Simplified the KabulTz example:
- Put the class definition itself into a non-REPL block since there is
no interactive output involved there
- Briefly explained what's happening before launching into the code
- Broke the example section into visually separate chunks
- Various whitespace, formatting, style and grammar fixes including:
- Consistently using backctics for 'date_string' formats
- Consistently using one space after periods.
- Consistently using bold for vocab terms
- Consistently using italics when referring to params:
See https://devguide.python.org/documenting/GH-id4
- Using '::' to lead into code blocks
Per https://devguide.python.org/documenting/GH-source-code, this will
let the reader use the 'expand/collapse' top-right button for REPL
blocks to hide or show the prompt.
- Using consistent captialization schemes
- Removing use of the default role
- Put 'example' blocks in Markdown subsections
This is a combination of 66 commits.

The purpose of the `unicodedata.is_normalized` function is to answer
the question `str == unicodedata.normalized(form, str)` more
efficiently than writing just that, by using the "quick check"
optimization described in the Unicode standard in UAX GH-15.
However, it turns out the code doesn't implement the full algorithm
from the standard, and as a result we often miss the optimization and
end up having to compute the whole normalized string after all.
Implement the standard's algorithm. This greatly speeds up
`unicodedata.is_normalized` in many cases where our partial variant
of quick-check had been returning MAYBE and the standard algorithm
returns NO.
At a quick test on my desktop, the existing code takes about 4.4 ms/MB
(so 4.4 ns per byte) when the partial quick-check returns MAYBE and it
has to do the slow normalize-and-compare:
$ build.base/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \
-- 'unicodedata.is_normalized("NFD", s)'
50 loops, best of 5: 4.39 msec per loop
With this patch, it gets the answer instantly (58 ns) on the same 1 MB
string:
$ build.dev/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \
-- 'unicodedata.is_normalized("NFD", s)'
5000000 loops, best of 5: 58.2 nsec per loop
This restores a small optimization that the original version of this
code had for the `unicodedata.normalize` use case.
With this, that case is actually faster than in master!
$ build.base/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \
-- 'unicodedata.normalize("NFD", s)'
500 loops, best of 5: 561 usec per loop
$ build.dev/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \
-- 'unicodedata.normalize("NFD", s)'
500 loops, best of 5: 512 usec per loop

Adds a link to `dateutil.parser.isoparse` in the documentation.
It would be nice to set up intersphinx for things like this, but I think we can leave that for a separate PR.

- drop TargetScopeError in favour of raising SyntaxError directly
as per the updated PEP 572
- comprehension iteration variables are explicitly local, but
named expression targets in comprehensions are nonlocal or
global. Raise SyntaxError as specified in PEP 572
- named expression targets in the outermost iterable of a
comprehension have an ambiguous target scope. Avoid resolving
that question now by raising SyntaxError. PEP 572
originally required this only for cases where the bound name
conflicts with the iteration variable in the comprehension,
but CPython can't easily restrict the exception to that case
(as it doesn't know the target variable names when visiting
the outermost iterator expression)

"Arguments may be integers... " could be misunderstand as they also

bpo-37834: Normalise handling of reparse points on Windows
* ntpath.realpath() and nt.stat() will traverse all supported reparse points (previously was mixed)
* nt.lstat() will let the OS traverse reparse points that are not name surrogates (previously would not traverse any reparse point)
* nt.[l]stat() will only set S_IFLNK for symlinks (previous behaviour)
* nt.readlink() will read destinations for symlinks and junction points only
bpo-1311: os.path.exists('nul') now returns True on Windows
* nt.stat('nul').st_mode is now S_IFCHR (previously was an error)
Added back mention that ensure_future actually scheduled obj. This documentation just mentions what ensure_future returns, so I did not realize that ensure_future also schedules obj.

The documented definition was much broader than the real one:
there are tons of characters with general category "Other",
and we don't (and shouldn't) treat most of them as whitespace.
Rewrite the definition to agree with the comment on
_PyUnicode_IsWhitespace, and with the logic in makeunicodedata.py,
which is what generates that function and so ultimately governs.
Add suitable breadcrumbs so that a reader who wants to pin down
exactly what this definition means (what's a "bidirectional class"
of "B"?) can do so. The `unicodedata` module documentation is an
appropriate central place for our references to Unicode's own copious
documentation, so point there.
Also add to the isspace() test a thorough check that the
implementation agrees with the intended definition.
Because mod, func, class, etc all share one namespace, :func:time creates a link to the time module doc page rather than the time.time function.

DeprecationWarning will continue to be emitted for invalid escape sequences in string and bytes literals in 3.8 just as it did in 3.7.
SyntaxWarning may be emitted in the future. But per mailing list discussion, we don't yet know when because we haven't settled on how to do so in a non-disruptive manner.

Expose the CAN_BCM SocketCAN constants used in the bcm_msg_head struct
flags (provided by <linux/can/bcm.h>) under the socket library.
This adds the following constants with a CAN_BCM prefix:
* SETTIMER
* STARTTIMER
* TX_COUNTEVT
* TX_ANNOUNCE
* TX_CP_CAN_ID
* RX_FILTER_ID
* RX_CHECK_DLC
* RX_NO_AUTOTIMER
* RX_ANNOUNCE_RESUME
* TX_RESET_MULTI_IDX
* RX_RTR_FRAME
* CAN_FD_FRAME
The CAN_FD_FRAME flag was introduced in the 4.8 kernel, while the other
ones were present since SocketCAN drivers were mainlined in 2.6.25. As
such, it is probably unnecessary to guard against these constants being
missing.

The `allow_abbrev` option for ArgumentParser is documented and intended to disable support for unique prefixes of --options, which may sometimes be ambiguous due to deferred parsing.
However, the initial implementation also broke parsing of grouped short flags, such as `-ab` meaning `-a -b` (or `-a=b`). Checking the argument for a leading `--` before rejecting it fixes this.
This was prompted by pytest-dev/pytestGH-5469, so a backport to at least 3.8 would be great 😄
And this is my first PR to CPython, so please let me know if I've missed anything!

Hi,
I've faced an issue w/ `mailbox.Maildir()`. The case is following:
1. I create a folder with `tempfile.TemporaryDirectory()`, so it's empty
2. I pass that folder path as an argument when instantiating `mailbox.Maildir()`
3. Then I receive an exception happening because "there's no such file or directory" (namely `cur`, `tmp` or `new`) during interaction with Maildir
**Expected result:** subdirs are created during `Maildir()` instance creation.
**Actual result:** subdirs are assumed as existing which leads to exceptions during use.
**Workaround:** remove the actual dir before passing the path to `Maildir()`. It will be created automatically with all subdirs needed.
**Fix:** This PR. Basically it adds creation of subdirs regardless of whether the base dir existed before.

This is done to compensate for the extra stack frames added by
IDLE itself, which cause problems when setting the recursion limit
to low values.
This wraps sys.setrecursionlimit() and sys.getrecursionlimit()
as invisibly as possible.
