从位置创建句子时发生逻辑错误

Question

我创建了这个程序，要求将位置列表输入到文件中，而不是将其保存为列表，并将其另存为另一个文件，用户必须输入每个位置具有的单词列表。例如，如果我输入：

1 2 3 4 5 1 2 3 4 5 

和

this is a repeated sentence 

的outpur应该

this is a repeated sentence this is a repeated sentence 

然而，当我运行我的代码，我得到的位置的列表，而不是

1 2 3 4 5 1 2 3 4 5 

这里是我的代码：

import subprocess 
process_position = subprocess.Popen(["notepad","list_of_numbers.txt"]) 
process_position.wait() 
positions = [] 
with open("list_of_numbers.txt","r") as f: 
    positions = f.read().split() 

process_words = subprocess.Popen(["notepad","list_of_words.txt"]) 
process_words.wait() 
sentence = "" 
with open("list_of_numbers.txt","r") as s: 
    sentence= s.read().split() 


mapping = {} 

for (position, word) in zip(positions, sentence): 
    mapping[position] = word 


output = [mapping[position] for position in positions] 

print(' '.join(output)) 

Answer 1

我觉得你很困惑。如果我理解正确的话，position列表就是您要打印的字位置列表。所以，你不想要的话从sentence.

一起zip它相反，只需使用position数的整数值查找词语的sentence列表：

result = [] 
for p in map(int, position): 
    result.append(sentence[p]) 

print(' '.join(result)) 

或者，挤点点：

print(' '.join([sentence[p] for p in map(int, position)]))
