因此,每当我使用小写字母时,我的Caesar密码程序运行良好。但是当我用大写输入单词或短语时,我希望它能够工作。这是我现在的代码。希望你们都能帮我完成这个。
def encrypt(消息,距离):“”“将获取消息并将其旋转距离,以便创建加密消息”“”
encryption = ""
for ch in message:
ordvalue = ord(ch)
cipherValue = ordvalue + distance
if cipherValue > ord("z"):
cipherValue = ord("a") + distance - (ord("z") - ordvalue + 1)
encryption += chr(cipherValue)
return encryption
def decrypt(消息,距离):“”“将解密上述消息”“”
decryption = ""
for cc in message:
ordvalue = ord(cc)
decryptValue = ordvalue - distance
if decryptValue < ord("a"):
decryptValue = ord("z") - distance - (ord("a") - ordvalue - 1)
decryption += chr(decryptValue)
return decryption
def binaryConversion(message):“”“将单词转换为二进制代码”“”
binary = ""
for cb in message:
binaryString = " " #Binary number
binaryNumber = ord(cb)
while binaryNumber > 0:
binaryRemainder = binaryNumber % 2
binaryNumber = binaryNumber // 2
binaryString = str(binaryRemainder) + binaryString
binary += binaryString
return binary
run = True
跑步时:
#input
message = input("Enter word to be encrypted: ") #original message
distance = int(input("Enter the distance value: ")) #distance letters will be moved
#variables
fancy = encrypt(message, distance)
boring = decrypt(fancy, distance)
numbers = binaryConversion(message)
#output
print("\n")
print("Your word was: ", format(message, ">20s"))
print("The distance you rotated was: ", format(distance), "\n")
print("The encryption is: ", format(fancy, ">16s"))
print("The decryption is: ", format(boring, ">16s"))
print("The binary code is: ", format(numbers)) #I know an error comes here but it will work in the end
repeat = input("Would you like to encrypt again? Y/N ")
print("\n")
if repeat == "N" or repeat == "n":
run = False
else:
run = True
打印(“谢谢你和Julius Caesar曾经说过'Veni,vidi,vici'”)
谢谢
我建议你在映射的思维模式而不是偏移量中解决这个问题。您可以基于偏移量构建映射,但如果使用字典或其他形式的一对一映射,则字符处理将更容易。
例如:
offset = 5
source = "abcdefghijklmnopqrstuvwxyz"
target = source[offset:]+source[:offset]
source = source + source.upper()
target = target + target.upper()
encrypt = str.maketrans(source,target)
decrypt = str.maketrans(target,source)
e = "The quick brown Fox jumped over the lazy Dogs".translate(encrypt)
print(e)
d = e.translate(decrypt)
print(d)
