itertools.count(start=0, step=1) Make an iterator that returns evenly spaced values starting with number start. Often

itertools.compress(data, selectors) Make an iterator that filters elements from data returning only those that have

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

operator.__ixor__(a, b) a = ixor(a, b) is equivalent to a ^= b.

operator.abs(obj) operator.__abs__(obj) Return the absolute value of obj.

operator.__ne__(a, b) operator.__ge__(a, b) operator.__gt__(a, b) Perform

operator.__floordiv__(a, b) Return a // b.

itertools.islice(iterable, stop) itertools.islice(iterable, start, stop[, step]) Make an iterator that returns selected

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

operator.__matmul__(a, b) Return a @ b.
