Question

sentence = input("Please enter a sentence:")
words = sentence.split()
position= [0]
myList = [] 

[myList.append(x) for x in words if x not in myList]
a =(" ".join(myList))
print (myList)
if words.count(i) <2:
    position.append(max(position) +1)
else:
    position.append(words.index(i) +1)

position.remove(0)

print (position)
words = str(words)
position = str(position)

file = open("recreated_positions","w")
file.write(a) 
file.write(position)
file.close()

这段代码将每个单词的位置作为数字，并在python shell和textfile上打印句子。

例如，如果句子是＆＃39;我喜欢英语，但我不喜欢数学＆＃39; 。该程序将输出

['i','like','english,'but','do','not','maths'] 
[1,2,3,4,1,5,6,2,7]

在文本文件中，程序不会以相同的方式输出句子在上面。

有关如何使其在文本文件中执行相同操作的任何建议吗？

Answer 1

首先，您需要从列表中删除重复项，然后使用index获取元素的位置：

sentence = raw_input("Please enter a sentence:")
words = sentence.split()

myList = []

for x in words:  
    if x not in myList:
        myList.append(x)

a = str(myList)

positions= [myList.index(word) + 1 for word in words]

print positions

file = open("recreated_positions","w")
file.write(a + '\n') 
file.write(str(positions))
file.close()

输出：

[1, 2, 3, 4, 1, 5, 6, 2, 7]

列在文本文件中的字符串？
