缺少 1 个必需的位置参数：“密钥”加密

Question

alphabet = ' abcdefghijklmnopqrstuvwxyz'
cryptMode = input("[E]ncrypt|[D]ecrypt: ").upper()
if cryptMode not in ['E','D']:
    print("Error: mode is not Found!"); raise SystemExit
startMessage = input("Write the message: ").upper()
try:rotKey = int(input("Write the key: "))
except ValueError: print("Only numbers!"); raise SystemExit
def encryptDecrypt(alphabet,mode,message,Key,final = ""):
    for c in message:
        if mode == 'E': 
            final += alphabet[(alphabet.index(c) + Key)%(len(alphabet))]
        else: 
            final += alphabet[(alphabet.index(c) - Key)%(len(alphabet))]
    return final
print("Final message:",encryptDecrypt(cryptMode, startMessage, rotKey))

收到此错误

print("最终消息：",encryptDecrypt(cryptMode, startMessage, rotKey)) TypeError: encryptDecrypt() 缺少 1 个必需的位置参数：'Key'\

无法理解我做错了什么

Answer 1

def encryptDecrypt(alphabet,mode,message,Key,final = ""): 需要 4 个参数和第五个可选参数。

您只需三个调用它：encryptDecrypt(cryptMode, startMessage, rotKey)，缺少alphabet。

更正：

encryptDecrypt(alphabet, cryptMode, startMessage, rotKey)
