--- Comment #3 from xqt info@gno.de --- cat.articles() is a generator and bool(cat.articles()) is always True.
You may try a simple performace test like:
import pwb, pywikibot as py s = py.Site() c = py.Category(s, 'Mann') c.categoryinfo['pages']
456626
You'll get the result above immediately
g = c.articles()
len(set(g))
You may wait several minutes to get a result. I've given up after 5.
