Re: Python+Glade+Gtk tutorial?
Warning: I'm only going to answer half of your questions :) I haven't built any GTK2/3 app in a while, but hopefully others here can address your other questions (although you might have better luck on the Python/GTK mailing list when it comes to finding a good tutorial, etc.) On 17 March 2015 at 03:13, Dave Farrance davefarra...@omitthisyahooandthis.co.uk wrote: A web-search told me that Glade seems to be most peoples choice (over QT-Designer) for a GUI builder. So even though I use a KDE desktop (Kubuntu 14.10), I decided to try Glade. In terms of toolkit bindings, (a) I prefer GTK, but (b) it's impossible to tell what the greater proportion of people using one vs. the other is. Or if they're wise to do so. Are there more Google hits/SO questions because it's harder to use? Or because everyone loves to use it? (And so on...) A recent comment on my SO answer to a similar question claims PyQT/PySide is a good way to go, with a couple of links there you might find interesting: http://stackoverflow.com/a/3290724/188535 I wouldn't stress over it though; you can give yourself a headache trying to decide between frameworks you've never developed in. Try one, commit to developing at least some proficiency in it, and then try the other. from gi.repository import Gtk, Gdk, GObject, Pango etc... ... I get, in effect, the libraries used in Gnome-3 even with python2? Yes. The GTK and Python versions are independent. You can make GTK3 apps with either Python 2 or 3. It's purely coincidence that Python 3 and GTK3 came out around the same time. Going the other way, Gnome 3 still includes some GTK2 apps, but I think you'd get little sympathy for starting a *new* app in GTK2 instead of 3. Am I on the right track now? Glade is a good choice for GUI building? And even though I'm using Python2, I should be ignoring all examples turned up by searching for PyGTK because they all seem to be GTK+2 and obsolete? Glade is good, although eventually you learn the lesson that it's not going to give you 100% control over your UI — there are some things you are better off doing in your app setup code. And yes, I'd recommend ignoring anything labelled PyGTK. — Jason -- https://mail.python.org/mailman/listinfo/python-list
Re: Module/lib for controlling a terminal program using redrawing?
Yes, Paul Rubin had it right: I hadn't thought of the term screen scraper, but that might help my searching.

Searching 'python terminal emulation' returns these Thanks for those results. I also discovered that someone wrote a Python ANSI terminal scraper originally for use with Nethack: https://github.com/helgefmi/ansiterm (although it seems generic enough).

Module/lib for controlling a terminal program using redrawing?
I am trying to automate the use of some old, in-house terminal-based programs that use screen redrawing for their interface. This includes single line redrawing (eg. using '\r' and overwriting), complete screen clearing, and fine-grained cursor movement and overwriting (probably not all in the same program at the same time though). Is there a module/library that can help me with this? I know of pexpect, but that seems more oriented towards line-by-line prompts that don't involve redraws (eg. login prompt, then password prompt on a new line). Think instead of trying to automate applications like emacs, aptitude or even nethack that redraw sections of the screen without making the terminal scroll. This automation requires more than just sending a set of keystrokes, but also reading what is displayed on screen and making decisions based up on that. Is there a library that can abstract the received redrawing activity so I don't have to even know if the application has, eg. used a carriage return or some other kind of cursor movement? Is there a way to just ask if this were to be run in an ANSI terminal, what would be in each cell? Python 2 or 3 are both fine, external packages are fine, but it has to work on Linux (eg. Ubuntu 14.04 or later, Debian Wheezy or later). Any pointers appreciated. Cheers, Jason -- https://mail.python.org/mailman/listinfo/python-list
[issue22046] ZipFile.read() should mention that it might throw NotImplementedError
Jason Heeris added the comment: Python documentation never document all possible exceptions raised by a method. No, but clearly *some* exceptions are documented, and presumably there's some reasoning behind which are and aren't. In this case, the NotImplemented error is there by design. It's not an incidental effect of something else. It's part of the API, and it's used to indicate a common error condition: that the compression format is not supported. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22046 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22046] ZipFile.read() should mention that it might throw NotImplementedError
New submission from Jason Heeris: As per issue 5701, the zipfile.ZipFile.read() method will throw a NotImplementedError if the compression scheme is not supported. However, there is no mention of this possibility in the documentation for the read() method. I would suggest, say, Calling read() on a ZipFile that uses an unsupported compression scheme (eg. implode) will raise a NotImplementedError. It looks like you can use the testzip() method to check that this won't happen (ie. after you open the file but before you extract an entry). If that is really the expected way to check for this kind of condition, it would be nice to mention that too (under either method). -- assignee: docs@python components: Documentation messages: 223737 nosy: detly, docs@python priority: normal severity: normal status: open title: ZipFile.read() should mention that it might throw NotImplementedError type: enhancement versions: Python 2.7, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22046 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
