operator.__or__(a, b) Return the bitwise or of a and b.

operator.inv(obj) operator.invert(obj) operator.__inv__(obj) operator

functools.reduce(function, iterable[, initializer]) Apply function of two arguments cumulatively to the items of sequence

@functools.singledispatch(default) Transforms a function into a single-dispatch

operator.iand(a, b) operator.__iand__(a, b) a = iand(a, b) is equivalent to a &= b

itertools.combinations(iterable, r) Return r length subsequences of elements from the input iterable.

operator.lshift(a, b) operator.__lshift__(a, b) Return a shifted left by b.

operator.__concat__(a, b) Return a + b for a and b sequences.

operator.__invert__(obj) Return the bitwise inverse of the number obj. This is equivalent to ~obj.

operator.ilshift(a, b) operator.__ilshift__(a, b) a = ilshift(a, b) is equivalent to a <<=
