我需要几周的时间进行编码,并且需要进行分配才能将文本输入加密到ascii,或者解密消息。我不能使用两个代码来加密和解密,这可以通过输入密码的负面版本来完成(因此功能)我自己进行了加密工作,但很难将其作为一个包工作。程序需要从用户那里获取一个选项(加密或解密,然后使用从text和key返回的值来转换main函数中的文本。 我已经在这里工作了10个小时,有很多研究和变化的元素,但似乎一直在下降。提供的任何建议都很棒。运行时的错误我已经放在代码下了。
def main(function, message, passkey):
#takes value of mode and applies text. then uses key to encrypt or decrypt
encrypt = ""
for x in message:
if x == " ":
encrypt += " "
else:
encrypt += chr((((ord(x) - 65) + passkey % 26) + 65))
def mode():
# determines either encryption or decryption.
func = input("Which mode would you like? E for encryption or D for decryption.\n").upper()
if func[0] =='E': return 'E'
elif func[0] == 'D': return 'D'
else: print("Not a valid option. Please try again")
def text():
#depending on value of mode, either input a sentance to encrypt or an ecrypted message to decode.
if function == 'E':
sentance = input("Please enter a sentance to encrypt.\n").upper()
if all(x.isalpha or x.isspace() for x in sentance):
return text
else: sentance = input("Only uppercase alpha characters and spaces allowed. Try again.\n")
else:
return input("Enter coded message for decrypting:\n")
def key():
#depending on value of mode, enter positve key to encrypt or same key in negative form to decrypt.
if function == 'E':
return abs(int(input("Enter passkey: ")))
elif function == 'D':
return -abs(int(input("Enter passkey: ")))
function = mode()
message = text()
passkey = key()
print (message)
print(main(function, message, passkey))

答案 0 :(得分:0)
在您的错误消息中,它表示'function' object is not iterable
。那是因为你正在返回text
这是一个函数。
要解决此问题,只需更改第28行中的return语句即可返回sentance
。您还需要在main
。
