Python 如何从txt文件导入原始输入/将原始输入写入txt文件
所以我是PythonN00B,我正在尝试破解这个脚本来创建一个端点加密工具。基本上,脚本接受原始输入,并使用16位字符串使用AES对其进行编码。为了解密该消息,您需要手动将编码文本粘贴到其中,然后是密钥。有没有办法将文本从文件中拉入,然后将编码文本输出到其他文件 到目前为止,我所掌握的情况如下:Python 如何从txt文件导入原始输入/将原始输入写入txt文件,python,encryption,lambda,Python,Encryption,Lambda,所以我是PythonN00B,我正在尝试破解这个脚本来创建一个端点加密工具。基本上,脚本接受原始输入,并使用16位字符串使用AES对其进行编码。为了解密该消息,您需要手动将编码文本粘贴到其中,然后是密钥。有没有办法将文本从文件中拉入,然后将编码文本输出到其他文件 到目前为止,我所掌握的情况如下: from Crypto.Cipher import AES import string import base64 import time #import modules PADDING = '{' B

您可以使用open('filename.extension','r/w/…')打开特定文件。然后可以使用read()、readline()或readlines()检查文件内容。要写入文件,只需按如下方式打开文件:
f = open('filename.txt', 'w') #make new file (open for write)
f.write('This is a test\n') #write to that file
