如何修改Python循环，在替换字典切换时插入CHANGE字符串

解决代码 #

words_input = "Duck Bear Bear Duck Duck Bear Bear Bear Bear Duck Bear Bear Duck Duck"

replacements = [{'Bear': ["Black", "Woods"], 'Duck': ["Bird", "Feathers"]},
                {'Bear': ["Grizzly", "Woods"], 'Duck': ["Quack", "Feathers"]},
                {'Bear': ["Grizzly", "Black"], 'Duck': ["Quack", "Bird"]}]

output = []
index_replace = 0
count_replace = {key: 0 for key in replacements[0].keys()}
for word in words_input.split():
    if count_replace[word] == len(replacements[index_replace][word]):
        # 切换替换字典
        index_replace = (index_replace + 1) % len(replacements)
        count_replace = {key: 0 for key in replacements[0].keys()}
        # 新增：切换后插入CHANGE标记
        output.append("CHANGE")
    idx_word = count_replace[word]
    output.append(replacements[index_replace][word][idx_word])
    count_replace[word] += 1

output_words = ' '.join(output)
print(output_words)

运行后输出结果和要求完全一致：
Bird Black Woods Feathers CHANGE Quack Grizzly Woods CHANGE Grizzly Black Quack CHANGE Black Woods Bird Feathers
