Python 3.x 从单词列表（无重复）和位置重新创建句子

我需要用单词和位置重新创建原始字符串。它不能引用回原始字符串

String = "ask not what your country can do for you ask"
words = ["ask","not","what","your","country","can","do","for","you","ask"]
positions = [1,2,3,4,5,6,7,8,9,1]

我可以重新创建句子，但我必须使用原始字符串

这回答：

String = "ask not what your country can do for you ask"
words = ["ask","not","what","your","country","can","do","for","you","ask"]
positions = [1,2,3,4,5,6,7,8,9,1]

String = "ask not what your country can do for you ask"
words = ["ask","not","what","your","country","can","do","for","you","ask"]
positions = [1,2,3,4,5,6,7,8,9,1]

for word in String():
   if not word in words:
      words.append(word)
   i = words.index(word)
   positions.append(i)

s = "" 
for i in positions:
   s = s + words[i] + " "

print(s)
