Type hinting: TypeError: 'type' object is not subscriptable
by Edward Ned Harvey (python) 30 Apr '17

30 Apr '17

Years ago, I fell in love with python and left C an C++ behind. Sometime later, I fell in love with C# because with strong typing, my IDE does most of the work for me - I never have to browse the API to find which method or attribute exists in a class, I can use tab completion for everything, avoid type-o's, etc. So I was recently thrilled to discover type hinting in python, and support included in pycharm. I'm coming back to python now (for the last few months). In python 3.6.1, and pycharm CE 2017.1.1 on windows (I haven't tested other versions or other platforms): The following is recognized and supported by pycharm, but then at runtime, python throws an exception: #!/usr/bin/env python3 def foo(bars: list[str]): for bar in bars: if bar.startswith("hi"): raise ValueError("bar should never say hi") return True if foo(["a","b","c"]): print("Ok") TypeError: 'type' object is not subscriptable The problem is that python doesn't recognize list[str] as a type. Pycharm handles it, and everything works fine if I'm using a non-subscripted type, like plain old int, or str, or anything else. Is this a bug, or is it something python simply hasn't implemented yet, or is it something that's not going to be implemented? Is there a workaround?

API for bugs.python.org or some statistic about lib/module merge rate?
by Louie Lu 28 Apr '17

28 Apr '17

Hi all, After reading some topic at python-committers mailing list, some of the topics are around not enough reviewers to review patches, cause the develop process slowing down or the patch can't merge into the codebase. I would like to make some analysis about module / library patch merge rate (maybe fine-grained to per file?), and make a statistic list that can point out which module / library need more people to contribute to it. Are there any API for bugs.python.org can be used, or there is a existing thing just doing what I want to do. (Or maybe Python tracker, who sent the summary can add this kind of function.) Thanks, Louie.

Details on replacing Python's dict object
by Jose Aaron Lopez Garcia 26 Apr '17

26 Apr '17

Hello: I'm attempting to replace Python's dict object with an algorithm I created myself to improve on memory and time consumption of hashmaps. My initial tests on the algorithm show that it manages to keep a stable logarithmic performance even with extremely high load factors (>0.9). My knowledge of C and Python are good enough but I only know how the interpreter works from a theoretical viewpoint, never really done any deep investigation into it. This said, I need expert help to port the algorithm, any insight into the details of the dict object is greatly appreciated (and please let it be as technical and guru-ish as possible). Regards J. Aaron Lopez.

Proposed BDFL Delegate update for PEPs 538 & 540 (assuming UTF-8 for *nix system boundaries)
by Nick Coghlan 24 Apr '17

24 Apr '17

Hi folks (mainly Guido), Due to constraints on his available time, Barry has decided to step down as BDFL-Delegate for PEP 538 (my proposal to default to coercing the legacy C locale to newer UTF-8 based locales when the latter are available). After discussion with Barry and Inada-san, Victor and I are now proposing to invite Naoki Inada to take on the task of being BDFL-Delegate for both PEP 538 and Victor's related PEP 540, with the following rationale: - the two PEPs are sufficiently closely related that Barry, Victor and I think the same person should be the final decision maker for both of them - with the initial delegation of PEP 538 to Barry, Guido indicated he'd prefer to delegate the task rather than having to come fully up to speed on the vagaries of modern *nix locale handling and the current state of the affected system boundaries in CPython - Inada-san has already been active in reviewing and commenting on both proposals - being based in Japan and working with Japanese text and interfaces, Inada-san regularly encounters the developer experience problems that these proposals are intended to help address Assuming Guido's OK with that proposed delegation, I'll update the headers on both PEPs accordingly. Cheers, Nick. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia

Python3 C extension how to support dir()
by Barry Scott 23 Apr '17

23 Apr '17

I first ask this on python users. But I think the only people that can answer are the core developers. I have a python3 C++ extension that works written using the PyCXX C++ interface. But dir(obj) does not return the list of member variables. With the python2 version supporting the __members__ variable was all that was needed. But __members__ been removed from python3. How should I support dir() from the C API? I cannot use tp_members, not appropiate to the code I'm writing. If I provide __dir__ I then hit the problem I need the C API version of: all_attr = super( mytype, obj ).__dir__(); all_attr.extend( mytype_variable_names ); return all_attr I'm not getting inspiration from the python 3.6 sources for this problem. I did find the object_dir function in typeobject.c, but that has not helped get me move forward. What is the the patten that I should implement? Barry PyCXX

Installing a newly-built python on windows
by joao.moreira＠free.fr 17 Apr '17

17 Apr '17

Hi all, I've followed the instructions in the 1st chapter (Getting Started) of the Python Developers's Guide to compile python 3.6 from source, using VS 2017 on a Windows 7 SP1. I successfully built 35 of the 40 subprojects, and the python interpreter in cpython\PCbuild\amd64 is working fine. How do I now install this, so that users on this machine can use it ? I've found no instrutions on how to do this, can someone point me in the right direction ? Alternatively, could someone point me to the source code for the python .msi installer ? Thx, Joao
