如何从唯一单词列表和位置重新创建一个句子

Question

我正在创建一个程序，它根据独特的单词及其位置重新创建一个句子。

至此我已经收集到了独特的词和原句的位置。

这是我的资料；

dictionary = {}#Creates an empty dictionary
List=[]#Creates an empty list



def play():
    unique = []
    sentence = "The fat cat, sat on the brick wall. The fat dog sat on the stone wall."#The original sentence
    splitted = sentence.split()


    for char in splitted:
        if char not in unique:#Finds the unique words
            unique.append(char)

    print(unique)#Prints the unique words


    for i,j in enumerate(splitted, 1):#puts i in each number next to each word, and j next to all the words in splitted
        if j in dictionary:#If the word is in dictionary
            List.append(dictionary[j])#The list will append the words position
        else:#Otherwise
            dictionary[j]=i#The dictionary will append the word and the number next to it
            List.append(i)#And then the list will take the number from it

    print(List)#Prints the Positions of the original sentence



play()#Plays the main loop

我坚持做的是找到一种使用独特的单词和原始句子的位置来重新创建原始句子的方法。任何想法都会有很大的帮助。

我正在使用Python 3.

如果您只想要一个列表中的唯一单词和包含相应单词出现索引的第二个列表，您可以这样做：

sentence = "I do not like sentences like this sentence"
unique = list()
idx = list()

for word in sentence.split():
   if not word in unique:
      unique.append(word)
   i = unique.index(word)
   idx.append(i)

s = "" # the reconstructed sentence
for i in idx:
   s = s + unique[i] + " "

print(s)
