试图压缩一个句子，然后上传到一个文件

Question

我有一个句子，我试图压缩它。然后我必须将其上传到外部文件。我的句子必须上传，而我的压缩句子在另一个文件中也一样。

这是我的计划......

word_dictionary = {} 
highest = 0 
sentence = "This is a sentence and is not a very long sentence".split() 
s= "This is a sentence and is not a very long sentence" 
compressed = [] 
new = "" 
for word in sentence: 
    if word not in word_dictionary: 
     highest += 1 
    compressed.append(word_dictionary.setdefault(highest, new)) 

print(word_dictionary) 

word_dictionary = str(word_dictionary) 

fo = open("index","a+") 
fo.write(word_dictionary) 
fo.close() 

fo=open("sentence","a+") 
fo.write(s) 
fo.close() 

我想上传到文件将是...

为 “指数” ---> 1,2,3， 4,5,2,6,3,7,8,4

为“句” --->“这是一个句子，是不是一个很长的句子”

请帮帮忙，谢谢

Answer 1

这应该工作，我修改原密码，并删除highest和word_dictionary，它的工作原理是，如果发生比在句子中再次追加元素index + 1，否则将追加数量最多的列表another，如果它是计数小于1，我也只好初始化another 0，以避免max()抛出异常的第一个元素

sentence = "This is a sentence and is not a very long sentence" 
s = sentence.split() 
another = [0] 

for i in s: 
    if s.count(i) < 2: 
     another.append(max(another) + 1) 
    else: 
     another.append(s.index(i) +1) 

another.remove(0) 

fo = open("index","w") 
for index in another: 
    fo.write(str(index)) 
fo.close() 

fo=open("sentence", "w") 
fo.write(sentence) 
fo.close()

您测试：

if word not in word_dictionary: 
... 

但你永远保存在字典中的任何字，而不是你保存highest计数器：

compressed.append(word_dictionary.setdefault(highest, new)) 

所以word永远不会在word_dictionary和highest总是会增加。
