operator.__ge__(a, b) operator.__gt__(a, b) Perform “rich comparisons” between a and b. Specifically

operator.lt(a, b) operator.le(a, b) operator.eq(a, b) operator

itertools.dropwhile(predicate, iterable) Make an iterator that drops elements from the iterable as long as the predicate is

@functools.lru_cache(maxsize=128, typed=False) Decorator to wrap a function with a memoizing callable that saves up to the maxsize

operator.__neg__(obj) Return obj negated (-obj).

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

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

itertools.takewhile(predicate, iterable) Make an iterator that returns elements from the iterable as long as the predicate is

operator.__isub__(a, b) a = isub(a, b) is equivalent to a -= b.

itertools.groupby(iterable, key=None) Make an iterator that returns consecutive keys and groups from the iterable.
