I am creating a program which recreates a sentence from it's unique words and the positions of them.
So far I have managed to collect the unique words and the positions of the original sentence.
Here's what I have;
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
What I am stuck on doing is finding a way of recreating the original sentence using the unique words and the positions of the original sentence. Any Ideas would be a great help.
I am using Python 3.

If you just want the unique words in a list and a second list containing the indices where the respective words occurred, you can do it like this:
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)
