請幫忙！如何在現有代碼中編寫條件，該代碼將進行如下檢查。請看評論區。我無法在字典/列表中附加值。我需要寫/更改什么？當用戶返回主菜單并使用相同的密鑰文件再次運行加密過程但以不同的名稱保存加密文件時。用戶可以使用相同的密鑰創建盡可能多的加密文件。我的嘗試：import Encryptfrom collections import defaultdictkey_value_dict = {}def encrypt_file(): try: txtfile = input("Your plain txt file that you want to encrypt : ") encrypt_file = input("Directory to save the encrypted file : ") key = input("Key for encryption : ") # process for encryption Encrypt.encrypt_file(txtfile, encrypt_file, key) # ---------------------------------------------------------------- key_value_dict = defaultdict(list, {key: encrypt_file}) print(key_value_dict) key_value_dict [key].append(encrypt_file) print(key_value_dict ) # -------------------------------------------------------------------- except FileNotFoundError: print("File Not Found!")def menu(): selection = True while selection: print("""MAIN MENU:[1] Encrypt files using existing keys.[2] Exit. """) try: selection = input("Please select : ") if selection == "1": encrypt_file() # call function elif selection == "2": print("\n[4] Keys are used for encryption:", "\n", key_value_dict) selection = None else: print("\n Invalid selection! Try again") except ValueError: print("\n Exception: Invalid user input!")# Main functionif __name__ == '__main__': menu()

如果我理解正確的話，我認為你不需要 defaultdict
嘗試這個：
# define this first outside the function like you have
encrypt_key_value_dict = {}
# Within your code block, get rid of the assignment to default dict
if encrypt_key_value_dict[key]:
encrypt_key_value_dict.append(encrypt_file)
else:
encrypt_key_value_dict[key] = [encrypt_file]
我無法從您的代碼中看到您的密鑰在哪里傳遞等，但我相信您可以弄清楚。
