Manual:Pywikibot/Cookbook/Creating and reading lists

Creating a list of pages is frequent task. For example A list may be saved to a file or to a wikipage. listpages.py does something like this, but the input is restricted to builtin page generators and output has a lot of options. If you write an own script, you may want a simple solution in place. Suppose that you have any iterable (list, tuple or generator) called  that contains your collection.
 * 1) You collect titles to work on because collecting is slow and can be done while you are sleeping.
 * 2) You want to review the list and make further discussions before you begin the task with your bot.
 * 3) You want to know the extent of a problem before you begin to write a bot for it.
 * 4) Listing is the purpose itself. It may be a maintenance list that requires attention from human users. It may be a community task list etc.
 * 5) Someone asked yo to create a list on which he or she wants to work.

Something like this: will give an appropriate list that is suitable both for wikipage and file. It looks like this:

On Windows sometimes you get a  when you try to save page names containing non-ASCII characters. In this case  will help: Of course, imports should be on top of your script, this is just a sample. While a file does not require the linked form, it is useful to keep them in the same form so that a list can be copied from a file to a wikipage at any time.

To retrieve your list from page Special:MyPage/Mylist use:

If you want to read the pages from the file to a list, do: If you are not familiar with regular expressions, just copy, it will work. :-)

Where to save the files?
While introducing the  directory is a great idea to separate your own scripts, using   your prompt is in the Pywikibot root directory. Once this structure is created so nicely, you may not want to mix your files into Pywikibot system files. Saving it to  requires to give the path every time, and is an unwanted mix again, because there are scripts rather than data.

A possible solution is to create a directory directly under Pywikibot root such as, which is short for "texts", is one letter long and very unlikely to appear at any time as a Pywikibot system directory:

Now instead  you may use   (use   both on Linux and on Windows!) when you save and open files. This is not a big pain, and your saved data will be in a separate directory.
