简单的输入-输出转换器

Question

我目前正在尝试制作一个简单的程序，它将接受用户的输入并根据简单的转换表输出相同的内容，但具有不同的字母/字符。

例如：假设以下是转换；左侧是用户的输入，右侧是程序的输出。

A=AB
B=BC
C=CD
D=DE
etc...

我想让程序接受一个句子或短语并吐出转换后的版本：

例如：这就是我想要的最终产品。

Input = Hello there
Output = HIEFLMLMOP TUHIEFRSEF

我必须承认，我对 Python 的经验很少。自从我在高中上编程课以来已经有 4 年多了，我们学习了 3.0 之前的旧版本，所以有些东西似乎是新的/不同的。非常感谢任何帮助！

import sys

'a' == "AB"
'b' == "BC"
'c' == "CD"
'd' == "DE"
'e' == "EF"
'f' == "FG"
'g' == "GH"
'h' == "HI"
'i' == "IJ"
'j' == "JK"
'k' == "KL"
'l' == "LM"
'm' == "MN"
'n' == "NO"
'o' == "OP"
'p' == "PQ"
'q' == "QR"
'r' == "RS"
's' == "ST"
't' == "TU"
'u' == "UV"
'v' == "VW"
'w' == "WX"
'x' == "XY"
'y' == "YZ"
'z' == "ZA"

usrinpt = input('Enter what you would like to encode:');
print("Generated Product:");
if input(usrinpt) == a:
    print ("AB")
def main():
    input("Press enter and exit")

尝试了@wwii 的建议，但似乎不知道如何让程序吐出转换。

import sys

translate = {"A": 'AB', "B": 'BC', "C": 2, "D": 3, "E": 4, "F": 5, "G": 6, "H": 7, "I": 8, "J": 9, "K": 10, "L": 11, "M": 12, "N": 13, "O": 14, "P": 15, "Q": 16, "R": 17, "S": 18, "T": 19, "U": 20, "V": 21, "W": 22, "X": 23, "Y": 24, "Z": 25, " ": 26}

conversion = input("What would you like cypher?: ").upper()
print("Here is the output: "conversion)

编辑3： 发现一些代码似乎非常接近我正在寻找的内容。只是很难让它阅读我的翻译。

key = 0

translate = {'a':'AB' , 'b':'BC'}
#going to add more to the translate list once I get those letters working

def wub():
    def choice():
        choice = input("Do you wish to Encrypt of Decrypt?")
        choice = choice.lower()
        if choice == "e" or "encrypt":
            return choice
        elif choice == "d" or "decrypt":
            return choice
        else:
            print("Invalid response, please try again.")
            choice()

    def message():
        user = input("Enter your message: ")
        return user

    def waffle(choice, message, key):
        translated = ""
        if choice == "e" or "encrypt":
            for character in message:
                num = ord(character)
                num += key
                translated += chr(num)

                derek = open('Encrypted.txt', 'w')
                derek.write(translated)
            derek.close()
            return translated
        else:
            for character in message:
                num = ord(character)
                num -= key
                translated += chr(num)
            return translated

    choice = choice() #Runs function for encrypt/decrypt selection. Saves choice made.
    message = message() #Run function for user to enter message. Saves message.
    final = waffle(choice, message, key) #Runs function to translate message, using the choice, message and key variables)
    print("\n Operation complete!")
    print(final)

在函数中尝试此操作或类似操作，您也许能够避免输出 str 。如果您希望处理小写字母，请检查 chr() 整数值，如果大于 96，则减去 32：

def convert(inputString):
    outputString = ""
    for letter in inputString:
        if ord(letter) >= 65 and ord(letter) < 86:
            outputString += letter + chr((ord(letter) + 1))
        elif ord(letter) >= 97 and ord(letter) < 122:
            outputString += chr(ord(letter) - 32) + chr(ord(letter) - 31)
        elif letter == 'z' or letter == 'Z':
            outputString += "ZA"
        else:
            outputString += letter
    return outputString

wordToConvert = "ABC abc"

print(convert( wordToConvert))

wordToConvert = "Hello there"

print(convert( wordToConvert))

输出：

ABBCCD ABBCCD
HIEFLMLMOP TUHIEFRSEF
