Description

I made a very simple script which simply prints the URL of a file. It throws a typeerror when the PageGenerator is being created.

#!/usr/bin/python
# -*- coding: utf-8 -*-

from __future__ import absolute_import, unicode_literals

import os

import pywikibot
from pywikibot import pagegenerators


def download(page):
    url = os.path.split(page.fileUrl())
    print(url)


def main(*args):
    generator = None
    local_args = pywikibot.handle_args(args)
    site = pywikibot.Site('commons', 'commons')
    genFactory = pagegenerators.GeneratorFactory(site)
    for arg in local_args:
        genFactory.handleArg(arg)

    generator = genFactory.getCombinedGenerator(gen=generator)
    if not generator:
        pywikibot.bot.suggest_help(missing_generator=True)
    else:
        pregenerator = pagegenerators.PreloadingGenerator(generator)
        site.login()
        for page in pregenerator:
            if page.exists() and not page.isRedirectPage():
                download(page)
            pywikibot.output("")

if __name__ == "__main__":
    main()

This gives a TypeError when I try to use the RandomPageGenerator
