Terry J. Reedy added the comment: Here is a more accurate 'equivalent': "any(x is e or <one of x==e or e==x> for e in <candidate members of y>)" where 'candidate members' is "members with the same hash as x" for built-in hash-based collections and 'all members' for built-in unsorted sequences". I am sure that built-in range does a direct calculation. Instead of the above, I suggest this.
"For general collections, such as list, tuple, collections.deque, and most iterables, the expression `x in y` is usually equivalent to `any(x is e or x == e for e in y)`." Hash-based collections should not be mentioned in such a sentence as the equivalency is completely wrong, as Steven noted. ---------- nosy: +terry.reedy _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27605> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
