Check if a page exists

If I use

if not pywikibot.Page.exists('Page'):
    #Do something

I get the error

[...]    

   title = self._link.canonical_title()

AttributeError: 'str' object has no attribute '_link'
CRITICAL: Exiting due to uncaught exception <class 'AttributeError'>

What I have to do? --ElBe (talk) 20:31, 20 January 2022 (UTC)

I think you should use it like this:

if not pywikibot.Page('Page').exists():

Thank you! --ElBe (talk) 05:58, 21 January 2022 (UTC)

It works if I use

[...]
page = pywikibot.Page(site, 'Page')
if not pywikibot.Page(page).exists():
   #Do something

Thank you! --ElBe (talk) 06:09, 21 January 2022 (UTC)

Hi ElBe, this is not a proper idea but it works by a side effect:

exists()

is a method of a Page object, more precisely of a BasePage object. You have to create the object first to use it:

page = pywikibot.Page(site, 'Page')

if not page.exists(): pass # or do something sensefull

Your example works because

pywikibot.Page(page)

clones the original page and creates a new Page object. This functionality to implemented to upcast objects e.g.

fp = pywikibot.FilePage(page)

which creates a FilePage object and provides further methods. But keep in mind that page must be in File: namespace here.

Count sections of a page

Hello. How I can count the number of sections on a page? --ElBe (talk) 18:37, 10 February 2022 (UTC)

You could create a script using extract_sections method from textlib (https://phabricator.wikimedia.org/diffusion/PWBC/browse/master/pywikibot/textlib.py). Or perhaps use external libraries like mwparserfromhell/wikitextparser to do that. Dvorapa (talk) 22:49, 10 February 2022 (UTC)

Ok, thanks. I will try it. --ElBe (talk) 05:23, 11 February 2022 (UTC)

Examples of bots and tools that rely on the Pywikibot framework

I'm looking for examples of active, helpful, and popular bots and tools that rely on the Pywikibot framework that we can highlight in an upcoming workshop on the topic as part of the "Small wiki toolkits" initiative. If you could point me to some examples, that would be super useful. Thank you! User:SSethi_(WMF) 03:52, 22 February 2022 (UTC)

See w:Category:Wikipedia bots using Pywikibot; there are a few dead bots there, but also a few active ones, including double redirect fixing bots. * Pppery * _{it has begun} 04:22, 22 February 2022 (UTC)

txt file and broken links do not get reported on the talk page with weblinkchecker

I'm trying the Manual:Pywikibot/weblinkchecker.py to obtain broken links on the page "Aeroflot" on test.wikipedia.org. It does generate a "deadlinks-wikipedia-test.dat" file. I am looking for a ".txt" file, but that isn't generated by re-running the command a second time as per instructions given in the manual. Also, I've modified the settings in "user-config.py" to set "report_dead_links_on_talk" to true to report the dead links on the talk page. That also doesn't seem to be working. Any leads? User:SSethi_(WMF) 20:56, 19 March 2022 (UTC)

After how long did you re-run the script and what was your command (did you set -day)? Usually with most parameters left in defaults you have to run the script and then re-run the script between one and two weeks later. Only then it will generate the second txt file and talk pages memos as expected. Dvorapa (talk) 20:10, 22 March 2022 (UTC)
