请求加密或多重加密，然后请求解密或退出

Question

我正在制作一个程序，将文本加密到一个文件中，然后将该文件保存到python保存到的任何目录中。在这个过程中，我有一个好主意，让程序询问用户是否希望继续进行更多加密，或者停止。现在我有了一个更聪明的想法，那就是询问他们是否想要解密或退出，但是我对如何才能工作有疑问。我有大约一个半月的经验，所以请保持简单，不要使用def（）或类似的东西

编辑：我现在已经让所有代码正常工作，除了else语句中的结尾。我想让用户选择重试拼写输入或退出程序。很难弄明白怎么做

#Input asking for encrypt or decrypt 
question = input("Are you Encrypting or Decrypting?: ")
encryptResult = ""

#While loop for multiple encrypts
while True:

#If statement for encrypt
    if question == 'Encrypting':

        #statements telling the user the choice they made
        print("So, you have chosen to encrpyt, very well then, lets hide some secrets.")

        #Asks user for phrase to encrypt
        encryptText = input("Enter the phrase you wish to encrypt, if you dare: ")

        #Asks user for file to save to
        createFile = input("Enter the file name you wish to save to: ")

        #For loop converting to ascii and adding 1
        for ch in encryptText:
            encryptValue = ord(ch) + 1
            bString = ""

            #While loop for conversion to binary
            while encryptValue > 0:
                remainder = encryptValue % 2
                encryptValue = encryptValue // 2

这是您在编辑后检查拼写错误的代码，无需进行太多修改。它只需要将问题设置为Spelling，然后在下一轮检查它以获得新的输入。您还有一项检查是多余的，根本不需要，即：

elif again == 'No':
    pass

# Input asking for encrypt or decrypt
question = input("Are you Encrypting or Decrypting?: ")
encryptResult = ""

# While loop for multiple encrypts
while True:

    # If statement for encrypt
    if question == 'Encrypting':

        # statements telling the user the choice they made
        print("So, you have chosen to encrpyt, very well then, lets hide some secrets.")

        # Asks user for phrase to encrypt
        encryptText = input("Enter the phrase you wish to encrypt, if you dare: ")

        # Asks user for file to save to
        createFile = input("Enter the file name you wish to save to: ")

        # For loop converting to ascii and adding 1
        for ch in encryptText:
            encryptValue = ord(ch) + 1
            bString = ""

            # While loop for conversion to binary
            while encryptValue > 0:
                remainder = encryptValue % 2
                encryptValue = encryptValue // 2
                bString = str(remainder) + bString

            # If statement moving characters to the left 1 time
