如何更改此循环以插入单词 "CHANGE"

Question

这是我正在使用的代码：

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]):
        # We need to cycle through the replacements
        index_replace = (index_replace + 1) % len(replacements)
        count_replace = {key: 0 for key in replacements[0].keys()}
    idx_word = count_replace[word]
    output.append(replacements[index_replace][word][idx_word])
    count_replace[word] += 1

output_words = ' '.join(output)
print(output_words)
# Bird Black Woods Feathers Quack Grizzly Woods Grizzly Black Quack Black Woods Bird Feathers

我希望每次字典列表更改时所需的输出都插入单词“CHANGE”，以便输出看起来像

Bird Black Woods Feathers CHANGE Quack Grizzly Woods CHANGE Grizzly Black Quack CHANGE Black Woods Bird Feathers

而不是

Bird Black Woods Feathers Quack Grizzly Woods Grizzly Black Quack Black Woods Bird Feathers

Answer 1

只需添加 output.append("CHANGE") 当...列表更改时？

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]):
        output.append("CHANGE") # << here is the change
        # We need to cycle through the replacements
        index_replace = (index_replace + 1) % len(replacements)
        count_replace = {key: 0 for key in replacements[0].keys()}
    idx_word = count_replace[word]
    output.append(replacements[index_replace][word][idx_word])
    count_replace[word] += 1

output_words = ' '.join(output)
print(output_words)
#Bird Black Woods Feathers CHANGE Quack Grizzly Woods CHANGE Grizzly Black Quack CHANGE Black Woods Bird Feathers

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]):
        # We need to cycle through the replacements
        index_replace = (index_replace + 1) % len(replacements)
        --- add--- output.append("CHANGE")
        count_replace = {key: 0 for key in replacements[0].keys()}
    idx_word = count_replace[word]
    output.append(replacements[index_replace][word][idx_word])
    count_replace[word] += 1

output_words = ' '.join(output)
print(output_words)
# Bird Black Woods Feathers Quack Grizzly Woods Grizzly Black Quack Black Woods Bird Feathers```
