I asked this question in February and got the same response. But on news.software.readers 16 May, Ted Heise posted a useful perl script. I'm starting to think I'll move to Perl for Usenet posting; I have yet to find a Python solution easy enough for this non-technical user.

So I'm not sure how that is working! I'd expect that you need to do: import cube cube.cubes() -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos

Tkinter (related)~
by Jack Dangler May 19, 2023

May 19, 2023

I didn't want to hijack another thread... I thought the OP of the tkinter thread currently running may have needed to install the tkinter package (since I had the same missing component error message), so I tried to install the package on to my Ubu laptop - pip install tkinter Defaulting to user installation because normal site-packages is not writeable ERROR: Could not find a version that satisfies the requirement tkinter (from versions: none) ERROR: No matching distribution found for tkinter Is there an alternate path to installing this? Thanks for any help you can provide... Jack

Silly (maybe) question re imported module(s)
by Grizzy Adams May 19, 2023

May 19, 2023

Morning All I'm working through the tutorial and running / saving work that I wish to keep and build on, most times I can save and (re)import later with no difference to when typed in console or editor and run with F5 (which saves before it can run) But sometimes saved work (albeit small) when imported does not work any longer I assume I have missed something, any pointers to what/how/why please

Learning tkinter
by Rob Cliffe May 18, 2023

May 18, 2023

I am trying to learn tkinter. Several examples on the internet refer to a messagebox class (tkinter.messagebox). But: Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:20:19) [MSC v.1925 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import tkinter >>> tkinter.messagebox Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: module 'tkinter' has no attribute 'messagebox' >>> Why is this?

Help on ImportError('Error: Reinit is forbidden')
by Jason Qian May 18, 2023

May 18, 2023

Hi, I Need some of your help. I have the following C code to import *Import python.* It works 99% of the time, but sometimes receives "*ImportError('Error: Reinit is forbidden')*". error. **We run multiple instances of the app parallelly. *** Python version(3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] PyObject * importPythonModule(const char* pmodName) { const char* errors = NULL; int nlen = strlen(pmodName); PyObject *pName = PyUnicode_DecodeUTF8(pmodName, nlen, errors); PyObject *pModule = *PyImport_Import*(pName); Py_DECREF(pName); if (pModule == NULL) { if (*PyErr_Occurred*()) { handleError("PyImport_Import()"); } } } void handleError(const char* msg) { ... "PyImport_Import() - ImportError('Error: Reinit is forbidden')" } Thanks Jason

Pip Error
by Aysu Mammadli May 17, 2023

May 17, 2023

I encountered an error while attempting to install pip using the terminal. The exact error message I received is: "An error occurred during configuration: option use-feature: invalid choice: '2020-resolver' (choose from 'fast-deps', 'truststore', 'no-binary-enable-wheel-cache')" Here are the steps I followed and the context of my system: Operating System: Windows 11 Python Version: 3.11.3 I executed the command in the terminal to install pip, but it resulted in the aforementioned error message. This error specifically references the '2020-resolver' choice within the 'use-feature' option. An error occurred during configuration: option use-feature: invalid choice: '2020-resolver' (choose from 'fast-deps', 'truststore', 'no-binary-enable-wheel-cache') I have already attempted the following troubleshooting steps without success: Checked my internet connectivity to ensure it was stable and not causing any issues. Verified that I have the latest version of pip installed, as well as the latest version of Python. Tried using alternative commands, such as using the --upgrade flag or specifying a specific pip version, but the error persists. Looked for any recent system updates or changes that could have caused this issue, but found none. I'm uncertain about the cause of this error and how to resolve it. Any insights or suggestions would be greatly appreciated. Thank you in advance for your assistance!
