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” \
无法理解我在做什么错
[def encryptDecrypt(alphabet,mode,message,Key,final = ""):
期望有四个参数,第五个可选参数。
您只用三个来称呼它:encryptDecrypt(cryptMode, startMessage, rotKey)
,缺少alphabet
。
更正:
encryptDecrypt(alphabet, cryptMode, startMessage, rotKey)
