New submission from FH: Upon inspection, random.randint(a,b) does not include the endpoint b, contrary to documentation, and contrary to the argumentation in Issue7009.
To see this, run e.g. sum(np.random.randint(0,1,1000)) which will return 0 repeatedly (statistically very unlikely). I tried both on Kubuntu 14.04/python 2.7 and pythoneverwhere.org Within random.py, randint is (in both 2.7 and 3.5) implemented as def randint(self, a, b): """Return random integer in range [a, b], including both end points. """ return self.randrange(a, b+1) which falsely seems to include the endpoint (as randrange excludes the endpoint). However, upon running it does not. ---------- components: Library (Lib) messages: 229765 nosy: georg.brandl, orsenthil, sciencebuggy priority: normal severity: normal status: open title: random.randint does not include endpoint type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22686> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
