Re: Python/Django Extract and append only new links
Max Cuban edze...@gmail.com writes: I am putting together a project using Python 2.7 Django 1.5 on Windows 7. I believe this should be on the django group but I haven't had help from there so I figured I would try the python list I have the following view: views.py: [snip] Right now as my code stands, anytime I run it, it scraps all the links on the frontpage of the sites selected and presents them paginated all afresh. However, I don't think its a good idea for the script to read/write all the links that had previously extracted links all over again and therefore would like to check for and append only new links. I would like to save the previously scraped links so that over the course of say, a week, all the links that have appeared on the frontpage of these sites will be available on my site as older pages. It's my first programming project and don't know how to incorporate this logic into my code. Any help/pointers/references will be greatly appreciated. regards, Max I don't know anything about Django, but I don't think this is a Django question. I think the best way would be to put the urls in a database with the time that they have been retrieved. Then you could retrieve the links from the database next time, and when present, sort them on time retrieved and put them at the end of the list. Now if you want to do this on a user basis you should add user information with it also (and then it would be partly a Django problem because you would get the user id from Django). -- Piet van Oostrum p...@vanoostrum.org WWW: http://pietvanoostrum.com/ PGP key: [8DAE142BE17999C4] -- https://mail.python.org/mailman/listinfo/python-list

Possibly you're trying to run print(Hello World) at the DOS command prompt rather than using Python. I'm not sure exactly what you're doing, but I do know that you shouldn't get any errors about the PRN device from Python. That sounds like it is a Windows error. I've got 2.x on Linux, so I booted into that and it seemed to work there, but it seems that the differences between the versions are not trivial. For the most part, they are trivial. With only a few exceptions, everything in Python 2 can be easily, even mechanically, translated to Python 3. Python 3 includes a lot of new features that a Python 2.3 book won't even mention. But if course, since the book doesn't mention them, you won't need to deal with them. It also includes a few changes from statements to functions, like print and exec (but as a beginner, you shouldn't be using exec). A few modules have been renamed. In my personal opinion, the most annoying change from Python 2 to 3 is renaming modules, because I can never remember the new name. None of these are *difficult* changes. As a beginner, of course, you cannot be expected to automatically know how to deal with a problem like this one: py from StringIO import StringIO Traceback (most recent call last): File stdin, line 1, in module ImportError: No module named 'StringIO' But let me give you a secret known only to a few: to solve this problem is not hard. Just google for StringIO renamed Python 3. which will take you to the What's New in Python 3 document, which reveals that the StringIO module is renamed to io.StringIO, and so you should use this instead: from io import StringIO https://duckduckgo.com/?q=StringIO%20renamed%20Python%203 If googling fails, feel free to ask here! -- Steven -- https://mail.python.org/mailman/listinfo/python-list

It owned little except a magic spell called Knowledge. In this chapter, I’ll examine how the Internet is changing our society. It’s happening quickly. The most significant changes have occurred during just the last 10 years or so. More and more of our knowledge about the world and other people is transmitted and stored digitally. What we know and who we know are moving out of our minds and into databases. These changes scare many people, whereas in fact they contain the potential to free us, empowering us to improve society in ways that were never before possible. -8-8-8-8-8-8-8-8- There is also a presentation of the content of the book that I didn't review yet.

Is there a way to update only a small part of the widget, while retaining the rest of the widget? In general, it would help to say which windowing toolkit you're using :) Fortunately you mention something that implies you're using QT, so I'm going to forge ahead with that. When you call update(), you're effectively saying the whole object needs to be repainted. If you can restrict that to just a particular rectangle, simply pass those coordinates to the update call: http://pyqt.sourceforge.net/Docs/PyQt4/qwidget.html#update-4 I'm not sure if you're using PyQt4 or not, but if you're using something else, look through its docs for a similar function. Same goes for pretty much any windowing toolkit; it's always possible to report that a small area needs updating. Once you then get the update event, you should be given a rectangle that tells you which part needs to be repainted. But painting outside that area will be reasonably fast, so don't stress too much about that part if it's a lot of trouble. For instance, I have a MUD client that will always attempt to draw complete lines, even if only part of a line needs to be redrawn - but it'll repaint only those lines which need repainting (so it looks at the Y coordinates of the please repaint me rectangle, but not the X coords).

According to a Stackoverflow issue, .write(n) will write n 0 bytes because it will send bytes(n) == n * bytes(b'\0'). PySerial is written in Python, so you could look at the .write method of the Serial class (presuming that 'ser' is an instance thereof) to see what it does. Quoting the full exception would help! My suspicion is that it works with byte strings, not Unicode strings. That is what the doc either says or implies. So you could do: ser.write(bstring) or: ser.write(string.encode()) to turn it into a stream of bytes (the latter uses UTF-8, the former would use your source file encoding). -- Terry Jan Reedy -- https://mail.python.org/mailman/listinfo/python-list

I've been experimenting with elasticsearch (to store JSON-format log
messages) and kibana (as a front-end search tool). The jury is still
out on how well it's going to work. It seems like a pretty powerful
combination, but there's definitely a bit of a learning curve to using
it.
I certainly like the idea of logging structured data, as opposed to
plain text. It opens up a world of better ways to search, slice, and
dice your log data.

[issue20104] expose posix_spawn(p)
New submission from Benjamin Peterson: posix_spawn is a nice, efficient replacement for fork()/exec().

[issue19108] Benchmark runner tries to execute external Python command and fails on error reporting
R. David Murray added the comment: The patch looks good to me, but since I'm not familiar with perf.py I'm not a good person to do a final review and commit it. One trivial question: why do you check for tupleness in PythonRuntime's init? Don't you control the input on both code paths to obtaining the version? -- nosy: +r.david.murray ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19108 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20104] expose posix_spawn(p)
Gregory P. Smith added the comment: Unless it could replace the fork+exec code path in its entirety, which I do not believe is possible, I see posix_spawn() as a distraction and additional maintenance burden with no benefit. http://pubs.opengroup.org/onlinepubs/759899/functions/posix_spawn.html Read the RATIONALE section. The posix_spawn API was not created to make subprocess creation easier (i'd argue that it is the same burden to setup a proper call to posix_spawn as it is to do everything right for fork and exec). One notable thing posix_spawn() does not support: setsid() (start_new_session=True) of the child process. Obviously it also couldn't handle the arbitrary preexec_fn but preexec_fn is in general considered harmful. -- priority: normal - low ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20104 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20098] email policy needs a mangle_from setting
R. David Murray added the comment: Sorry, my message wasn't clear. The current default needs to remain the same. What needs to be added is email.policy.Policy.mange_from, which should be True in the compat32 policy and False in EmailPolicy. Then it needs to be hooked up the Generator, so that an explicit specificaion in the __init__ overrides the policy, but specifying one of EmailPolicy dervived policies will override the default value of the __init__ argument if the argument is not speicifed explicitly in the Generator constructor call.
