Re: dict.get_deep()
Hello,
Yes, I misunderstood as well because started to think about pattern
matching which is good but this is not subject the question was about.
Sorry for my mistake.
Because question was about 'builtin' function which means stdlib
function implemented in python itself or even in C.
It seems, maybe I miss again, but we are talking about similar ideas
behind 'xpath' or 'jsonpath' or even 'LINQ'. We want to find some 'dsl'
which give us simple and safe way to get deeply nested values from dict.
There are several similar solutions on pypi
(https://pypi.org/project/dpath/, https://pypi.org/project/path-dict/).
But maybe (and maybe I miss again) we talk about language embedded
solution like operator ? or ??.
For example deep dict extraction could look like: street =
data["users"]?[0]?["address"]?["street"]?.

I may have misunderstood something.
The original post in this subject sounded to ME likethey had nested
dictionaries and wanted to be ableto ask a method in the first dictionary
totake an unspecified number of arguments thatwould be successive keys and
return the results.
I mean if A was a dictionary containing saycities and it had an alphabetical
index of lettersA to Z and those contained dictionaries ofsay last names as
additional dictionaries andso on, then they wanted to perhaps say;
A.getdeep("Boston", "S", "Smith", "Address", default="None")
But the replies I am seeing look so different that I mayhave missed something
as it seems more about usingpattern matching on the data used to make the
dictionariesor something.
So I was happy to see Marco suggesting a function alongthe lines of my thought
process. But I have another thought.A stand-alone function along his lines
might be fine. Buta method built into a general Dictionary class is
anotherthing as it asks a method in one dictionary to march aroundinto other
dictionaries. So I wonder if a better methodis sort of recursive.
If you had a class like dictionary that had a getdeep function,and it got
called with N arguments, and perhaps a namedargument supplying a default, then
would it make sensefor the function checking to see if the FIRST argument canbe
found as a key to the current dictionary.
If arguments remain then it should expect to finda result that is a dictionary
(or perhaps some otherobject that supports the getdeep() protocol and ask
thatobject to operate on the N-1 remaining arguments, passingthe default along
too.
If the request is valid, after some iterations an object willhave a method
invoked with a single argument (plus default)and a value passed back up the
chain. For any errors alongthe way, the default would be returned.
Is this closer to the spirit of the request? I view this versionof nested
dictionaries as a sort of tree structure with variablebranches along the way.
So an approach like this could makesense and perhaps Python could be updated
eventually to havesome objects support such a protocol.
Of course you could sort of do it yourself by subclassing somethingand making
changes but that may not work for what is already asort of built-in data
structure but could work for one of many variantsalready implemented in modules.

Yep. Did that, too. Plus pass the final result through a function before
returning it.
I didn't understand. Have you added a func parameter?
I'm not sure whether I considered this when I wrote it, but a function
has the advantage of working with every class which can be indexed. A
method must be implemented on any class (so at least dict and list to be
useful).
You're right, but where to put it? I don't know if an iterableutil package
exists. If included in the stdlib, I don't know where to put it. In
collections maybe?
PS: if you're interested, here is my implementation:
def get_deep(self, *args, default=_sentinel):
r"""
Get a nested element of the dictionary.
The method accepts multiple arguments or a single one. If a single
argument is passed, it must be an iterable. This represents the
keys or indexes of the nested element.
The method first tries to get the value v1 of the dict using the
first key. If it finds v1 and there's no other key, v1 is
returned. Otherwise, the method tries to retrieve the value from v1
associated with the second key/index, and so on.
If in any point, for any reason, the value can't be retrieved, the
`default` parameter is returned if specified. Otherwise, a
KeyError or an IndexError is raised.

Re: dict.get_deep()
Kirill,
There are many related needs and issues and solutions such as how to parse XML
content and do all kinds of tree searches for "patterns" that multiple modules
have been created to deal with.
My impression here was of a simpler request to allow a list of keys to be
applied in sequence. The example wanted the list to be successive arguments in
a call to a method, but obvious variants would be for a single argument
containing atuple or list or any interator that would probe a tree of
possibilities while anchored to the top.
This is a much easier task with many solutions offered.

ANN: eGenix Antispam Bot for Telegram 0.2.0
ANNOUNCING eGenix Antispam Bot for Telegram Version 0.2.0 A simple, yet effective bot implementation to address Telegram signup spam. This announcement is also available on our web-site for online reading: https://www.egenix.com/company/news/eGenix-Antispam-Bot-for-Telegram-0.2.0-GA.html INTRODUCTION eGenix has long been running a local user group meeting in Düsseldorf called Python Meeting Düsseldorf and we are using a Telegram group for most of our communication. In the early days, the group worked well and we only had few spammers joining it, which we could well handle manually. More recently, this has changed dramatically. We are seeing between 2-5 spam signups per day, often at night. Furthermore, the signups accounts are not always easy to spot as spammers, since they often come with profile images, descriptions, etc. With the bot, we now have a more flexible way of dealing with the problem. Please see our project page for details and download links: https://www.egenix.com/library/telegram-antispam-bot/ FEATURES * Low impact mode of operation: the bot tries to keep noise in the group to a minimum * Several challenge mechanisms to choose from, more can be added as needed * Flexible and easy to use configuration * Only needs a few MB of RAM, so can easily be put into a container or run on a Raspberry Pi * Can handle quite a bit of load due to the async implementation * Works with Python 3.9+ * MIT open source licensed NEWS The 0.2.0 release is the first public release of the bot. It has been battle-tested in production for more than a month already and is proving to be a really useful tool to help with Telegram group administration. ___ INFORMATION About eGenix (http://www.egenix.com/): eGenix is a database focused software project, consulting and product company delivering expert services and professional quality products for companies, Python users and developers.

The Cython compiler is 20 years old today !
Dear Python community, it's now 20 years since Greg Ewing posted his first announcement of Pyrex, the tool that is now known and used under the name Cython. https://mail.python.org/pipermail/python-list/2002-April/126661.html It was a long way, and I've written up some of it in a blog post: http://blog.behnel.de/posts/cython-is-20/ Today, if you're working on any kind of larger application in Python, you're likely to have some piece of code downloaded into your venv that was built with Cython. Or many of them. I'm proud of what we have achieved. And I'm happy to see and talk to the many, many users out there whom we could help to help their users get their work done. Happy anniversary, Cython! Stefan PS: The list of Cython implemented packages on PyPI is certainly incomplete, so please add the classifier to yours if it's missing. With almost 3000 dependent packages on Github (and almost 100,000 related repos), I'm sure we can crack the number of 1000 Cython built packages on PyPI as a birthday present.
