gh-69142: add %:z strftime format code (gh-95983)
datetime.isoformat generates the tzoffset with colons, but there
was no format code to make strftime output the same format.

for simplicity and consistency the %:z formatting behaves mostly
as %z, with the exception of adding colons. this includes the
dynamic behaviour of adding seconds and microseconds only when
needed (when not 0).

this fixes the still open "generate" part of this issue:

Update documentation in datetime module strftime-and-strptime-behavior fix typo in '%W' format code description (GH-30232)
A small change to the documentation of datetime module , in the format codes section of stftime and strptime. Changed the description of format code '%W' from 'as a decimal number' to 'a zero padded   decimal number' so it's in line with the example having leading zeros.  Similar to the format code '%U' above.

bpo-24416: Return named tuple from date.isocalendar() (GH-20113)
{date, datetime}.isocalendar() now return a private custom named tuple object
IsoCalendarDate rather than a simple tuple.

In order to leave IsocalendarDate as a private class and to improve what
backwards compatibility is offered for pickling the result of a
datetime.isocalendar() call, add a __reduce__ method to the named tuples that
reduces them to plain tuples. (This is the part of this PR most likely to cause
problems — if it causes major issues, switching to a strucseq or equivalent
would be prudent).

The pure python implementation of IsoCalendarDate uses positional-only
arguments, since it is private and only constructed by position anyway; the
equivalent change in the argument clinic on the C side would require us to move
the forward declaration of the type above the clinic import for whatever
reason, so it seems preferable to hold off on that for now.

Brad 3fb1363fe8 Overhaul datetime documentation (GH-13410)
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/#id4
    - Using '::' to lead into code blocks
        Per https://devguide.python.org/documenting/#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.

Mario Corchero f0b5ae4567 bpo-30699: Improve example on datetime tzinfo instances (GH-4290)
* Improve example on tzinfo instances

Move from GMTX to TZX when naming the classes, as GMT1 might be rather
confusing as seen in the reported issue.
In addition, move to UTC over GMT and improve the tzname implementation.

* Simplify datetime with tzinfo example

Move the example in the documentation to just use timezone.utc and a
user defined Kabul timezone rather than having two user defined
timezones with DST.

Kabul timezone is still interesting as it changes its offset but not
based on DST. This is more accurate as the previous example was missing
information about the fold attribute. Additionally, implementing the fold
attribute was rather complex and probably not relevant enough for the
section "datetime with tzinfo".

Christophe Nanteuil 92878829c3 bpo-34158: Documentation UTC offset update (GH-8377)
* Documentation of UTC offset update
Since changes in the UTC offset that allows sub-minute offsets, the documentation needs update:

- "%z" format code documentation update
Karthikeyan Singaravelan commented on bugs.python.org:
Added as part of 018d353c1c and a fix regarding duplicate words for that part was added at bac2d5ba30.
Relevant format string at https://github.com/python/cpython/pull/2896/files#diff-25e2d173c84057d069b7890450714eddR214.
Relevant test case with 6-digit string for microsecond : https://github.com/python/cpython/pull/2896/files#diff-acc40bec51c7de832de3361db3edae52R309.
Table at https://docs.python.org/3.7/library/datetime.html#strftime-and-strptime-behavior could also be updated with microseconds being optional in the second column
%z | UTC offset in the form ±HHMM[SS] (empty string if the object is naive). | (empty), +0000, -0400, +1030

- isoformat documentation update
According to me, needs confirmation:
Relevant format string at https://github.com/python/cpython/pull/4699/files#diff-25e2d173c84057d069b7890450714eddR176
Relevant test case at https://github.com/python/cpython/pull/4699/files#diff-25e2d173c84057d069b7890450714edd

bpo-33812: Corrected astimezone for naive datetimes. (GH-7578)
A datetime object d is aware if d.tzinfo is not None and
d.tzinfo.utcoffset(d) does  not return None. If d.tzinfo is None,
or if d.tzinfo is not None but d.tzinfo.utcoffset(d) returns None,
 d is naive.

This commit ensures that instances with non-None d.tzinfo, but
d.tzinfo.utcoffset(d) returning None are treated as naive.

In addition, C acceleration code will raise TypeError if
d.tzinfo.utcoffset(d) returns an object with the type other than
timedelta.

* Updated the documentation.

Assume that the term "naive" is defined elsewhere and remove the
not entirely correct clarification.  Thanks, Tim.
