如何從一個txt文件導入raw_input /將raw_input寫入一個txt文件

Question

所以我是一個Python n00b，我試圖破解這個腳本來創建一個終點加密工具。基本上，腳本使用raw_input並使用16位數字符串使用AES對其進行編碼。爲了解密該消息，您需要手動粘貼已編碼的文本，然後粘貼密鑰。有沒有辦法從文件中拉出文本，然後將編碼文本輸出到不同的文件？

這裏是我迄今：

from Crypto.Cipher import AES 
import string 
import base64 
import time 
#import modules 
PADDING = '{' 
BLOCK_SIZE = 32 
pad = lambda s: s + (BLOCK_SIZE - len(s) % BLOCK_SIZE) * PADDING 
#prepare crypto method 
EncodeAES = lambda c, s: base64.b64encode(c.encrypt(pad(s))) 
DecodeAES = lambda c, e: c.decrypt(base64.b64decode(e)).rstrip(PADDING) 
#set encryption/decryption variables 
loop=5 
while loop==5: 
    #set up loop, so the program can be rerun again if desired without restarting 
    option=raw_input("Would You Like to Encrypt Or Decrypt Text?\nEncrypt: a\nDecrypt: b\n") 
    if option=='a': 
     letter=3 
     while letter==3: 
      secret = raw_input("Please Enter An Encryption Key {must be 16 characters long}: ") 
      countTotal= (len(secret)) 
      if countTotal==16: 
       cipher = AES.new(secret) 
       letter=0 
      else: 
       print "Please Ensure The Key You Entered Is 16 Characters In Length\n" 
       letter=3 
       #this checks the encryption key to ensure it matches the correct length 
     # encode a string 
     data=raw_input("Please Enter Text You'd Like Encrypted: ") 
     encoded = EncodeAES(cipher, data) 
     print 'Encrypted string:', encoded 
     options=raw_input("Would You Like To Encrypt/Decrypt Again? Y/N\n") 
     if options=='y': 
      loop=5 
     if options=='n': 
      loop=0 

    if option=='b': 

     encoded=raw_input("Please Enter The Encoded String:\n") 
     letter=3 
     while letter==3: 
      secret=raw_input("Please Enter The Decryption Key:\n") 
      countTotal= (len(secret)) 
      #this checks the encryption key to ensure it matches the correct length 
      if countTotal==16: 
       cipher = AES.new(secret) 
       letter=0 
       decoded = DecodeAES(cipher, encoded) 
       print 'Decrypted string:', decoded 
       options=raw_input("Would You Like To Encrypt/Decrypt Again? Y/N\n") 
       if options=='y': 
        loop=5 
       if options=='n': 
        loop=0 
      else: 
       print "Please Ensure The Key You Entered Is 16 Characters In Length\n" 
       letter=3 

if loop==0: 
    print "Goodbye!!" 
    time.sleep(2) 
    exit 
    #exits the program if desired by user

你可以打開一個特定的文件，打開（ 'filename.extension'， 'R/W/...'）。然後，您可以通過read（），readline（）或readlines（）來瀏覽文件的內容。要寫入文件，只需打開一個文件是這樣的：

f = open('filename.txt', 'w')  #make new file (open for write) 
f.write('This is a test\n')  #write to that file
