我該如何解決？

Question

我如何獲得該程序將文件壓縮為單詞列表和位置列表，以重新創建原始文件。 然后，獲取壓縮文件並重新創建原始文件的全文，包括標點和大寫。

startsentence = input("Please enter a sentence: ")
sentence = (startsentence)
a = startsentence.split(" ")
dict = dict()
number = 1
positions = []
for j in a:
    if j not in dict:
        dict[j] = str(number)
        number = number + 1
    positions.append(dict[j])
print (positions)


print(positions)
f = open("postions.txt", "w") 
f.write( str(positions) + "\n"  )
f.close()

print(sentence)
f = open("words.txt", "w") 
f.write( str(startsentence) + "\n"  ) 
f.close() 

Answer 1

當前，您正在寫出整個startsentence ，而不僅僅是唯一的單詞：

f = open("words.txt", "w") 
f.write( str(startsentence) + "\n"  ) 
f.close()

您只需要編寫唯一的單詞及其索引，就已經用這些單詞及其索引dict創建了一個字典（順便說一句，您確實不應該將dict用作變量名，所以我將使用dct ）。 您只需要根據它們的值（使用with語句）將它們寫出：

with open("words.txt", "w") as f:
    f.write(' '.join(sorted(dct, key=dct.get)) + '\n')

假設您有一個職位列表（順便說一句：從0開始比1容易得多），並且有一個單詞列表，那么恢復很簡單：

with open('positions.txt') as pf, open('words.txt' as wf:
    positions = [int(p) for p in pf.read().split()]  
    words = wf.read().strip().split()

recovered = ' '.join(words[p] for p in positions) # p-1 if you start from 1
