Python 凯撒密码，大写字母

因此，目前我的凯撒密码程序运行良好，每当我使用小写字母。但是，当我输入大写的单词或短语时，我希望它能够工作。这就是我现在的代码。希望你们能帮我完成这件事

用户定义函数 def加密（消息、距离）： “”“将接收邮件并将其旋转一定距离，以便创建加密邮件”“”

def解密（消息、距离）： “”“将解密上述消息”“”

while循环 运行=真

运行时：

#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

结局 印刷品（“谢谢你&正如朱利叶斯·凯撒曾经说过的，‘威尼斯、维迪、维西’”）

谢谢

我建议您以映射而不是偏移的心态来处理这个问题。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，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)

我想我错过了。我试过了，但我也需要用大写字母从解密中打印出来

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

#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

  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)
