This fixes an issue on tutorial/classes.rst section 9.4 where the example "class Warehouse"
was truncated when pressing the >>> button to hide the prompts and output.
#85757https://docs.python.org/3/tutorial/datastructures.html#nested-list-comprehensions
I do think this is clearer, but I wonder if 'nested' should be kept though to get the terminology out there more often. So perhaps it could be something like 'inner (nested) listcomp' or 'nested (inner) listcomp' despite sounding a bit redundant

Add a link to the `match` statement from its section in the tutorial.
This should be backported to 3.10.
[Initially submitted as #31395 but against the wrong branch. Thanks @Mariatta]

The "Color" example in the pattern-matching section of the "control flow" documentation is not immediately runnable, leading to confusion.

@vsajip Sorry for the trouble—made a [fairly significant] git error in the previous PR.
Have edited the patch as you had said in #28959.

Replace old names when they refer to actual versions of macOS.
Keep historical names in references to older versions.

Broadened scope of the document to explicitly discuss and differentiate between ``__main__.py`` in packages versus the ``__name__ == '__main__'`` expression (and the idioms that surround it), as well as ``import __main__``.

This documents in the tutorial docs the behavior of a finally clause in
case it should re-raise an exception but contains a
return/break/continue statement.
Links for 'raise Exception from x' target to 'The raise statement' (7.8) section instead of 'The import statement' (7.11) section.
There are more modified links than in the bug report because I searched some other ones which can get the same improvement.
In the [official tutorial on virtual environment](https://docs.python.org/3/tutorial/venv.html#creating-virtual-environments)
> This will create the tutorial-env directory if it doesn’t exist, and also create directories inside it containing a copy of the Python interpreter, **the standard library**, and various supporting files.
According to the actual behavior of `venv` and [PEP 405](https://www.python.org/dev/peps/pep-0405/#id15)'s description about virtual environment, no standard library file is included in the virtual environment's directory.

This is a first edition, ready to go out with the implementation. We'll iterate during the rest of the period leading up to 3.10.0.

Improvements:
- Improvements in how try clause works section
This suggestion is because the execution continues after *except*, not after *try* but before *except*. I guess this form more clear.
- Surrounding some keywords with \*...\*
For uniformity the highlighted terms
- Adjust the number of chars per line to 80
* Update errors.rst
Clarify exception chaining behaviour and give a reference to the library documentation.
* Update errors.rst
Wording
* Update errors.rst
Spelling
* Update errors.rst
Remove mentioning of special attributes as folks think it's too much for beginners.
This commit reverts commit ac0333e1e1 as the original links are working again and they provide extended features such as comments and alternative versions.
Sphinx 3 requires to refer to terms with the exact case.
For example, fix the Sphinx 3 warning:
Doc/library/pkgutil.rst:71: WARNING: term Loader not found in case
sensitive match.made a reference to loader instead.
* Use a more universal explanation of string interpolation rather than specifically referencing sprintf(), which depends on the reader having a C background.

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.html#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 to help prevent people from accidentally installing into the wrong Python interpreter if they are not aware of which Python interpreter `pip` points to.
