[RELEASE] Python 3.13.0 beta 2 released.
by Thomas Wouters June 7, 2024

June 7, 2024

After a little bit of a delay (I blame the flat tire on my rental car), 3.13.0b2 is released: https://www.python.org/downloads/release/python-3130b2/ <https://www.python.org/downloads/release/python-3130b2/> <https://discuss.python.org/t/3-13-0b2-now-available/55056#this-is-a-beta-pr…>This is a beta preview of Python 3.13 Python 3.13 is still in development. This release, 3.13.0b2, is the second of four beta release previews of 3.13. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We *strongly encourage* maintainers of third-party Python projects to *test with 3.13* during the beta phase and report issues found to the Python bug tracker <https://github.com/python/cpython/issues> as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (Tuesday 2024-07-30). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.13.0rc1, the first release candidate. To achieve that, it will be *extremely important* to get as much exposure for 3.13 as possible during the beta phase. *Two particularly noteworthy changes in beta 2 involve the macOS installer we provide:* - The minimum supported macOS version was changed from 10.9 to *10.13 (High Sierra)*. Older macOS versions will not be supported going forward. - The macOS installer package now includes an optional additional build of Python 3.13 with the experimental free-threading feature enabled. The free-threaded version, python3.13t, is separate from and co-exists with the traditional GIL-only installation. The free-threaded build is not installed by default; use the Customize option of the installer as explained in the installer readme. Since this is an experimental feature, there may be late-breaking issues found; see the free-threaded macOS build issue <https://github.com/python/cpython/issues/120098> on GitHub for the most recent status. Please keep in mind that this is a preview release and its use is *not* recommended for production environments. <https://discuss.python.org/t/3-13-0b2-now-available/55056#major-new-feature…>Major new features of the 3.13 series, compared to 3.12 Some of the new major new features and changes in Python 3.13 are: <https://discuss.python.org/t/3-13-0b2-now-available/55056#new-features-2>New features - A new and improved interactive interpreter <https://docs.python.org/3.13/whatsnew/3.13.html#a-better-interactive-interp…>, based on PyPy <https://pypy.org>’s, featuring multi-line editing and color support, as well as colorized exception tracebacks <https://docs.python.org/3.13/whatsnew/3.13.html#improved-error-messages> . - An *experimental* free-threaded build mode <https://docs.python.org/3.13/whatsnew/3.13.html#free-threaded-cpython>, which disables the Global Interpreter Lock, allowing threads to run more concurrently. - A preliminary, *experimental* JIT <https://docs.python.org/3.13/whatsnew/3.13.html#experimental-jit-compiler>, providing the ground work for significant performance improvements. - The (cyclic) garbage collector is now incremental <https://docs.python.org/3.13/whatsnew/3.13.html#incremental-garbage-collect…>, which should mean shorter pauses for collection in programs with a lot of objects. - A modified version of mimalloc <https://github.com/microsoft/mimalloc> is now included, optional but enabled by default if supported by the platform, and required for the free-threaded build mode. - Docstrings now have their leading indentation stripped <https://docs.python.org/3.13/whatsnew/3.13.html#other-language-changes>, reducing memory use and the size of .pyc files. (Most tools handling docstrings already strip leading indentation.) - The dbm module <https://docs.python.org/3.13/library/dbm.html> has a new dbm.sqlite3 backend <https://docs.python.org/3.13/whatsnew/3.13.html#dbm> that is used by default when creating new files. <https://discuss.python.org/t/3-13-0b2-now-available/55056#typing-3>Typing - Support for type defaults in type parameters <https://peps.python.org/pep-0696/>. - A new type narrowing annotation <https://peps.python.org/pep-0742/>, typing.TypeIs. - A new annotation for read-only items in TypeDicts <https://peps.python.org/pep-0705/>. <https://discuss.python.org/t/3-13-0b2-now-available/55056#removals-and-new-…>Removals and new deprecations - PEP 594 (Removing dead batteries from the standard library) <https://peps.python.org/pep-0594/> scheduled removals of many deprecated modules: aifc, audioop, chunk, cgi, cgitb, crypt, imghdr, mailcap, msilib, nis, nntplib, ossaudiodev, pipes, sndhdr, spwd, sunau, telnetlib, uu, xdrlib, lib2to3. - Many other removals <https://docs.python.org/3.13/whatsnew/3.13.html#removed> of deprecated classes, functions and methods in various standard library modules. - C API removals <https://docs.python.org/3.13/whatsnew/3.13.html#id10> and deprecations <https://docs.python.org/3.13/whatsnew/3.13.html#id9>. (Some removals present in alpha 1 were reverted in alpha 2, as the removals were deemed too disruptive at this time.) - New deprecations <https://docs.python.org/3.13/whatsnew/3.13.html#deprecated>, most of which are scheduled for removal from Python 3.15 or 3.16.

Fwd: IDLE: clearing the screen
by Rob Cliffe June 5, 2024

June 5, 2024

Welcome to Python! A great language for program development. Answers might be platform-dependent (are you using WIndows, Linux, etc.). However, the following works for me on WIndows. You can put it in the startup.py file so you don't have to type it every time you start up the IDLE. import os def cls(): x=os.system("cls") Now whenever you type cls() it will clear the screen and show the prompt at the top of the screen. (The reason for the "x=" is: os.system returns a result, in this case 0. When you evaluate an expression in the IDE, the IDE prints the result. So without the "x=" you get an extra line at the top of the screen containing "0".) I am sure that some jiggery-pokery could be used so you don't have to type the "()". But that's more advanced ...

That's another problem, because "plain text" means UTF-8....and that means unicode...and that means running some sort of unicode-to-ascii conversion in order to get something like "words".

IDLE: clearing the screen

June 4, 2024

Hello everyone, I am new to Python, and I have been using IDLE (v3.10.11) to run small Python code. However, I have seen that the output scrolls to the bottom in the output window. Is there a way to clear the output window (something like cls in command prompt or clear in terminal), so that output stays at the top? Thanks in anticipation!

From JoyceUlysses.txt -- words occurring exactly once
by HenHanna June 1, 2024

June 1, 2024

Given a text file of a novel (JoyceUlysses.txt) ... could someone give me a pretty fast (and simple) Python program that'd give me a list of all words occurring exactly once? -- Also, a list of words occurring once, twice or 3 times re: hyphenated words (you can treat it anyway you like) but ideally, i'd treat [editor-in-chief] [go-ahead] [pen-knife] [know-how] [far-fetched] ... as one unit.

Cannot install python properly - python310.dll not found - no pip
by Jay Cadet | Studio JPC June 1, 2024

June 1, 2024

Hi. I'm attempting to install and use stable diffusion. However, while installing python 3.10.6, I'm getting the error that the python 310.dll is not found. I've made sure the PATH option is enabled, but it makes no difference. I've also removed and reinstalled python multiple times. Even though I get that error, the python still installs, but when I open the webui-user.bat file in the stable diffusion folder, it opens up the command center and says that there's no module named pip. Please advise on how to fix this problem. Thank you, Jay Cadet Architectural 3D Artist / Photographer studio JPC [p] 516.567.1996 | [w] studiojpc.com<http://studiojpc.com> | [ig] @studiojpc
