我怎样才能为这个函数写一个递归？

def randomWord(args):
    yield random.choice(args)

list = ['book', 'apple', 'word']
books = randomWord(list)
print(next(books))
print(next(books))
print(next(books))
print(next(books))
print(next(books))

在每个print(next(books)) 我需要从list

从 Python 3.3 开始，您可以只使用yield from关键字。

def randomWord(args):
    yield random.choice(args)
    yield from randomWord(args)

list = ['book', 'apple', 'word']
books = randomWord(list)
print(next(books))
print(next(books))
print(next(books))
print(next(books))
print(next(books))
