Re: The repr of a sentinel
by Eric Nieuwland 16 May '21

16 May '21

To add to the suggestions already given in this thread I dug into code I wrote some time ago. Offered as an inspiration. === missing.py === from typing import Any def MISSING(klass: Any) -> Any: """ create a sentinel to indicate a missing instance of a class :param klass: the class of which an instance is missing :return: missing class object """ g = globals() missing_klass_name = f"_MISSING_{klass.__module__}_{klass.__name__}_MISSING_" if missing_klass_name not in g: g[missing_klass_name] = type( missing_klass_name, (klass,), { "__repr__": lambda x: f"MISSING({klass.__name__})", } ) return g[missing_klass_name]() === and as a demo: === demo_missing.py === import pickle from missing import MISSING x = MISSING(str) y = "bar" print(f"{x!r} == {y!r}: {x == y}") print(f"{x!r} is {y!r}: {x is y}") # MISSING(str) == 'bar': False # MISSING(str) is 'bar': False with open("object.pickled", "wb") as f: pickle.dump(x, f) with open("object.pickled", "rb") as f: y = pickle.load(f) print(f"{x!r} == {y!r}: {x == y}") print(f"{x!r} is {y!r}: {x is y}") # MISSING(str) == MISSING(str): True # MISSING(str) is MISSING(str): False def foo(a: int = MISSING(int), b: int = MISSING(int)): print(f"{a=} {isinstance(a, int)}") print(f"{b=} {isinstance(b, int)}") print(f"{a!r} == {b!r}: {a == b}") print(f"{a!r} is {b!r}: {a is b}") foo() # a=MISSING(int) True # b=MISSING(int) True # MISSING(int) == MISSING(int): True # MISSING(int) is MISSING(int): False foo(1) # a=1 True # b=MISSING(int) True # 1 == MISSING(int): False # 1 is MISSING(int): False class Test: ... t = MISSING(Test) print(f"{t=}") # t=MISSING(Test) ===

Future PEP: Include Fine Grained Error Locations in Tracebacks
by Pablo Galindo Salgado 13 May '21

13 May '21

Hi there, We are preparing a PEP and we would like to start some early discussion about one of the main aspects of the PEP. The work we are preparing is to allow the interpreter to produce more fine-grained error messages, pointing to the source associated to the instructions that are failing. For example: Traceback (most recent call last): File "test.py", line 14, in <module> lel3(x) ^^^^^^^ File "test.py", line 12, in lel3 return lel2(x) / 23 ^^^^^^^ File "test.py", line 9, in lel2 return 25 + lel(x) + lel(x) ^^^^^^ File "test.py", line 6, in lel return 1 + foo(a,b,c=x['z']['x']['y']['z']['y'], d=e) ^^^^^^^^^^^^^^^^^^^^^ TypeError: 'NoneType' object is not subscriptable The cost of this is having the start column number and end column number information for every bytecode instruction and this is what we want to discuss (there is also some stack cost to re-raise exceptions but that's not a big problem in any case). Given that column numbers are not very big compared with line numbers, we plan to store these as unsigned chars or unsigned shorts. We ran some experiments over the standard library and we found that the overhead of all pyc files is: * If we use shorts, the total overhead is ~3% (total size 28MB and the extra size is 0.88 MB). * If we use chars. the total overhead is ~1.5% (total size 28 MB and the extra size is 0.44MB). One of the disadvantages of using chars is that we can only report columns from 1 to 255 so if an error happens in a column bigger than that then we would have to exclude it (and not show the highlighting) for that frame. Unsigned short will allow the values to go from 0 to 65535. Unfortunately these numbers are not easily compressible, as every instruction would have very different offsets. There is also the possibility of not doing this based on some build flag on when using -O to allow users to opt out, but given the fact that these numbers can be quite useful to other tools like coverage measuring tools, tracers, profilers and the such adding conditional logic to many places would complicate the implementation considerably and will potentially reduce the usability of those tools so we prefer not to have the conditional logic. We believe this is extra cost is very much worth the better error reporting but we understand and respect other points of view. Does anyone see a better way to encode this information **without complicating a lot the implementation**? What are people thoughts on the feature? Thanks in advance, Regards from cloudy London, Pablo Galindo Salgado

Necessary or not for enhancement of issue44097: “add configure option to control the groups of .pyc files to install”
by Xin, Peixing 12 May '21

12 May '21

Hi , I created issue44097 for build enhancement: “add configure option to control the groups of .pyc files to install” and PR 23920 for the solution. From the only a few of comments I’ve got, someone thinks this enhancement makes sense. However, someone expressed opposition to this. So what is your opinion on this PR? Necessary or not? I want to hear more views on this. Thanks. https://bugs.python.org/issue44097 https://github.com/python/cpython/pull/23920 Thanks, Peixing

Important: Python3.10 what's new
by Pablo Galindo Salgado 11 May '21

11 May '21

Hi everyone, Now that we are in the beta period for 3.10 is very important that we make sure that all improvements, new APIs and deprecations are reflected in the 3.10 what's New document. IMPORTANT!! If you have worked on: * Make a PEP that affects Python 3.10. * A new feature/class/function/argument/option... * Deprecating something. * Remove something. * Improve something important. Please, make sure is reflected on the What's new document for Python 3.10. Users normally don't read the changelog directly and learn about what's available from the What's New document so you *absolutely* want your work to be reflected there. *Small* tutorials and small code samples and descriptions are a fantastic thing to add as well. Specially for deprecations and removals, this is our public window to the world so that learn what's coming or how to port code to Python 3.10. Thanks for helping to make Python3.10 a great release. Regards from sunny London, Pablo Galindo Salgado

The importance of mental health
by Kyle Stanley 10 May '21

10 May '21

Hey all, In these last few months, I have been in the process of healing from some pretty heavy past trauma. And now that I am on the road to recovery, I want to share my journey with the Python community in hopes that it may reach those that are struggling with their own mental health battles, as many of us are during these dark and difficult times. Trigger warning that it includes a decent amount of highly personal content, so only check it out if you are okay with that: https://discuss.python.org/t/break-from-open-source/6372/7?u=aeros. To anyone that would limit my employment opportunities as a result of having had these struggles, *that's perfectly okay*. I kept the post in the private section because I was originally in fear of discriminate. However, I have reached an important conclusion: *I would not want to work for your company if you discriminate against people who have overcome past struggles* . -- --Kyle R. Stanley, Python Core Developer (what is a core dev? <https://devguide.python.org/coredev/>) *Pronouns: they/them **(why is my pronoun here?* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-…> )

That's this bit: ``` except (A, B): ^^^^^^ ``` bpo-43149 currently calls it an "exception group", but that conflicts with PEP 654 -- Exception Groups and except* ``` >>> try: ... pass ... except A, B: ... pass Traceback (most recent call last): SyntaxError: exception group must be parenthesized ``` some alternatives: exception classinfo must be parenthesized (classinfo so named from the parameter to issubclass) exception sequence must be parenthesized see also: - https://github.com/python/cpython/pull/24467#discussion_r628756347 - https://www.python.org/dev/peps/pep-0654/

On the migration from master to main
by Python Steering Council 10 May '21

10 May '21

From Thomas Wouters, on behalf of and with full support of the Python Steering Council: This discussion seems to have died down a little, but I still want to make a few things clear: Yes, this is a political decision. Very many decisions are political. The existence of an open-source project is inherently political. The decision to try and make python-dev more welcoming, more open, more helpful is also a political decision -- one that the SC feels is absolutely necessary for the long-term health of the Python language. Not wanting to be bothered by political decisions is a political decision; it’s a decision that you’re happy with politics as they are. I’m afraid you can’t avoid politics. This isn’t just about ‘master’ being rooted in slavery. This is about what the community sees and does. As I mentioned before, we’re not leading the pack in this, we’re merely following along with others (like, say, Django). There are undoubtedly other terms and practices that are genuinely offensive, and the decision on how to handle them will be taken on a case-by-case basis, weighing the cost and the benefit in each case. While you may feel the benefit of this change is small and that it has no real impact, we believe that there is little cost to making this change. We believe this change, while a minor inconvenience to some, helps demonstrate our commitment to acting in the best interests of Python's future. Failure to make a small sacrifice, such as this, signals that the Python core development community would be unlikely to undertake real change for greater benefits. This isn’t happening because GitHub/Microsoft made a political decision. It’s happening because it is incredibly easy to make this move, many projects have already done this, and it reflects badly on any project not making this change. Speaking for the whole SC in this, Thomas.
