*******************
-A dictionary display is a possibly empty series of dict items
-(key/value pairs) enclosed in curly braces:
-
- dict_display: "{" [dict_item_list | dict_comprehension] "}"
- dict_item_list: dict_item ("," dict_item)* [","]
- dict_comprehension: dict_item comp_for
- dict_item: expression ":" expression | "**" or_expr
-
-A dictionary display yields a new dictionary object.
-
-If a comma-separated sequence of dict items is given, they are
-evaluated from left to right to define the entries of the dictionary:
-each key object is used as a key into the dictionary to store the
-corresponding value. This means that you can specify the same key
-multiple times in the dict item list, and the final dictionary’s value
-for that key will be the last one given.
-
-A double asterisk "**" denotes *dictionary unpacking*. Its operand
-must be a *mapping*. Each mapping item is added to the new
-dictionary. Later values replace values already set by earlier dict
-items and earlier dictionary unpackings.
+A *dictionary display* is a possibly empty series of *dict items*
+enclosed in curly braces. Each dict item is a colon-separated pair of
+expressions: the *key* and its associated *value*. For example:
+
+ >>> {1: 'one', 2: 'two'}
+ {1: 'one', 2: 'two'}
+
+At runtime, when a dictionary comprehension is evaluated, the
+expressions are evaluated from left to right. Each key object is used
+as a key into the dictionary to store the corresponding value. This
+means that you can specify the same key multiple times in the
+comprehension, and the final dictionary’s value for a given key will
+be the last one given. For example:
+
+ >>> {
+ ... 1: 'this will be overridden',
+ ... 2: 'two',
+ ... 1: 'also overridden',
+ ... 1: 'one',
+ ... }
+ {1: 'one', 2: 'two'}
+
+Instead of a key-value pair, a dict item may be an expression prefixed
+by a double asterisk "**". This denotes *dictionary unpacking*. At
+runtime, the expression must evaluate to a *mapping*; each item of the
+mapping is added to the new dictionary. As with key-value pairs, later
+values replace values already set by earlier items and unpackings.
+This may be used to override a set of defaults:
+
+ >>> defaults = {'color': 'blue', 'count': 8}
+ >>> overrides = {'color': 'yellow'}
+ >>> {**defaults, **overrides}
+ {'color': 'yellow', 'count': 8}
Added in version 3.5: Unpacking into dictionary displays, originally
proposed by **PEP 448**.
-A dict comprehension may take one of two forms:
-
-* The first form uses two expressions separated with a colon followed
- by the usual “for” and “if” clauses. When the comprehension is run,
- the resulting key and value elements are inserted in the new
- dictionary in the order they are produced.
-
-* The second form uses a single expression prefixed by the "**"
- dictionary unpacking operator followed by the usual “for” and “if”
- clauses. When the comprehension is evaluated, the expression is
- evaluated and then unpacked, inserting zero or more key/value pairs
- into the new dictionary.
-
-Both forms of dictionary comprehension retain the property that if the
-same key is specified multiple times, the associated value in the
-resulting dictionary will be the last one specified.
-
-Restrictions on the types of the key values are listed earlier in
-section The standard type hierarchy. (To summarize, the key type
-should be *hashable*, which excludes all mutable objects.) Clashes
-between duplicate keys are not detected; the last value (textually
-rightmost in the display) stored for a given key value prevails.
+The formal grammar for dict displays is:
-Changed in version 3.8: Prior to Python 3.8, in dict comprehensions,
-the evaluation order of key and value was not well-defined. In
-CPython, the value was evaluated before the key. Starting with 3.8,
-the key is evaluated before the value, as proposed by **PEP 572**.
-
-Changed in version 3.15: Unpacking with the "**" operator is now
-allowed in dictionary comprehensions.

+ 'lazy': r'''Lazy imports
+************
+
+The "lazy" keyword is a soft keyword that only has special meaning
+when it appears immediately before an "import" or "from" statement.
+When an import statement is preceded by the "lazy" keyword, the import
+becomes *lazy*: the module is not loaded immediately at the import
+statement. Instead, a lazy proxy object is created and bound to the
+name. The actual module is loaded on first use of that name.
+
+Lazy imports are only permitted at module scope. Using "lazy" inside a
+function, class body, or "try"/"except"/"finally" block raises a
+"SyntaxError". Star imports cannot be lazy ("lazy from module import
+*" is a syntax error), and future statements cannot be lazy.
+
+When using "lazy from ... import", each imported name is bound to a
+lazy proxy object. The first access to any of these names triggers
+loading of the entire module and resolves only that specific name to
+its actual value. Other names remain as lazy proxies until they are
+accessed.
+
+Example:
+
+ lazy import json
+ import sys
+
+ print('json' in sys.modules) # False - json module not yet loaded
+
+ # First use triggers loading
+ result = json.dumps({"hello": "world"})
+
+ print('json' in sys.modules) # True - now loaded
+
+If an error occurs during module loading (such as "ImportError" or
+"SyntaxError"), it is raised at the point where the lazy import is
+first used, not at the import statement itself.
+
+See **PEP 810** for the full specification of lazy imports.
+
+Added in version 3.15.
+
+
+Compatibility via "__lazy_modules__"
+====================================
+
+As an alternative to using the "lazy" keyword, a module can opt into
+lazy loading for specific imports by defining a module-level
+"__lazy_modules__" variable. When present, it must be a container of
+fully qualified module name strings. Any regular (non-"lazy")
+"import" statement at module scope whose target appears in
+"__lazy_modules__" is treated as a lazy import, exactly as if the
+"lazy" keyword had been used.
+
+This provides a way to enable lazy loading for specific dependencies
+without changing individual "import" statements. This is useful when
+supporting Python versions older than 3.15 while using lazy imports in
+3.15+:
+
+ __lazy_modules__ = ["json", "pathlib"]
+
+ import json # loaded lazily (name is in __lazy_modules__)
+ import os # loaded eagerly (name not in __lazy_modules__)
+
+ import pathlib # loaded lazily
+
+Relative imports are resolved to their absolute name before the
+lookup, so "__lazy_modules__" must always contain fully qualified
+module names.
+
+For "from"-style imports, the relevant name is the module following
+"from", not the names of its members:
+
+ # In mypackage/mymodule.py
+ __lazy_modules__ = ["mypackage", "mypackage.sub.utils"]
+
+ from . import helper # loaded lazily: . resolves to mypackage
+ from .sub.utils import func # loaded lazily: .sub.utils resolves to mypackage.sub.utils
+ import json # loaded eagerly (not in __lazy_modules__)
+
+Imports inside functions, class bodies, or "try"/"except"/"finally"
+blocks are always eager, regardless of "__lazy_modules__".
+
+Setting "-X lazy_imports=none" (or the "PYTHON_LAZY_IMPORTS"
+environment variable to "none") overrides "__lazy_modules__" and
+forces all imports to be eager.
+
+Added in version 3.15.

-Update bundled pip to 26.1.2
+++ /dev/null
-Improved protection against XML hash-flooding attacks in
-:mod:`xml.parsers.expat` and :mod:`xml.etree.ElementTree` when Python is
-compiled with libExpat 2.8.0 or later.
+++ /dev/null
-Fix a potential denial of service in :func:`unicodedata.normalize`. The
-canonical ordering step of Unicode normalization used a quadratic-time insertion
-sort for reordering combining characters, which could be exploited with
-crafted input containing many combining characters in non-canonical order.
-Replaced with a linear-time counting sort for long runs.
+++ /dev/null
-:func:`tarfile.data_filter` now validates link targets using the same
-normalised value that is written to disk, strips trailing separators from
-the member name when resolving a symlink's directory, and rejects link
-members that would replace the destination directory itself. This closes
-several path-traversal bypasses of the ``data`` extraction filter.
+++ /dev/null
-Fix the binary writer in :mod:`profiling.sampling` not firing the audit
-(:pep:`578`) when creating the output file. The writer and the reader now
-accept any path-like object. Patch by Maurycy Pawłowski-Wieroński.
+++ /dev/null
-The :mod:`ftplib` module's undocumented ``ftpcp`` function no longer trusts
-the IPv4 address value returned from the source server in response to the
-``PASV`` command by default, completing the fix for CVE-2021-4189. As with
-:class:`ftplib.FTP`, the former behavior can be re-enabled by setting the
-``trust_server_pasv_ipv4_address`` attribute on the source :class:`ftplib.FTP`
-instance to ``True``. Thanks to Qi Deng at Aurascape AI for the report.
+++ /dev/null
-Update bundled `libexpat <https://libexpat.github.io/>`_ to version 2.8.1
-for the fix for :cve:`2026-45186`.
+++ /dev/null
-Fix test_socket on Linux kernel 7.1 and newer: skip UDP Lite tests if it's
-not supported. Patch by Victor Stinner.
+++ /dev/null
-Fix hang in
-``test.test_profiling.test_sampling_profiler.test_live_collector_ui.TestLiveModeErrors.test_run_failed_script_live``
-on slow buildbots. The test now always queues a final ``q`` keystroke so the
-live TUI loop exits even when the profiler collects enough samples to enter
-the post-finished input loop.
+++ /dev/null
-Update the tooltip on the Tachyon flame graph to show both absolute and relative percentages.
+++ /dev/null
-Update Windows installer to ship with SQLite 3.53.1.
+++ /dev/null
-Windows distributions now include a :file:`build-details.json` file (see
-:pep:`739`). The legacy installer does not install it, but all other
-distributions from python.org and all preset configurations in the
-``PC\layout`` script will include one.
+++ /dev/null
-Updated Windows builds to use Tcl/Tk 9.0.3.
+++ /dev/null
-Fixes virtual environment launchers on Windows free-threaded builds.
+++ /dev/null
-Update macOS installer to ship with SQLite version 3.53.1.
+++ /dev/null
-When system logging is enabled (with ``config.use_system_logger``, messages
-are now tagged as public. This allows the macOS 26 system logger to view
-messages without special configuration.
-This is Python version 3.15.0 beta 1
+This is Python version 3.15.0 beta 2
