试图将摩尔斯电码翻译成英文

Question

我正在尝试用我使用的字典将摩尔斯电码翻译成英语。我试图在用户输入消息的地方使用它，它将 his/her 消息打印成摩尔斯电码。

我发现翻译成摩尔斯电码很容易，但是将摩尔斯电码翻译成英语给我带来了一些问题。

首先，如果我为 'A' 输入“.-”，我实际上得到的是 'E'，因为它正在读取第一个“.”。键并将其翻译成 'E' 而不是获取整个字符串。

这是我迄今为止尝试过的方法:)

#If user types 'N' or 'n' it proceeds this loop
if morse_message == 'N' or morse_message == 'n':    #Loops looks to see if morse_message was 'N' or 'n'
    nomorse = input("Enter your Morse code here:")
    nomorse_list = (nomorse.join('')
    for letter in nomorse_list:
        not_morse = (morse_eng_dict[letter.upper()])
        print(not_morse)

这是我的字典

morse_eng_dict = {".-": "A", "-...": "B", "-.-.": "C", "-..": "D", ".": "E",
                  "..-.": "F", "--.": "G", "....": "H",
                  "..": "I", ".---": "J", "-.-": "K", ".-..": "L",
                  "--": "M", "-.": "N", "---": "O", ".--.": "P",
                  "--.-": "Q", ".-.": "R", "...": "S", "-": "T", "..-": "U", "...-": "V",
                  ".--": "W", "-..-": "X", "-.--": "Y", "--..": "Z"}

我想让 Python 获取我的摩尔斯电码并将消息打印回英文。比如像... .-.. .-.. ---（这是你好）

这是一个项目，所以我不能使用任何花哨的模块或任何东西。有什么想法或意见吗？谢谢！

Answer 1

摩尔斯电码是用歧义构建的。正如您所指出的。-可以被视为 e t 或 a。如果不求助于大词典或一些模糊逻辑，就无法轻松区分它们。

operator 倾向于使用 spaces 来分隔字母和单词： https://en.wikipedia.org/wiki/Morse_code

"The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots." 如果您插入 spaces，例如：在字母之间插入 1 space，在单词之间插入 2 spaces，到您的莫尔斯电码字符串中使解码变得小菜一碟（拆分然后映射）

Answer 2

像这样的东西应该可以工作：基本上，只要有 space，它就会拆分字符串，生成一个列表，其中每个项目都是莫尔斯电码字母。然后它会根据字典检查每个字母并获取对应的英文字母。最后，它将所有这些放入一个列表中，再次将其转换为字符串并打印出来。希望对您有所帮助！

morse_eng_dict = {".-": "A", "-...": "B", "-.-.": "C", "-..": "D", ".": "E",
"..-.": "F", "--.": "G", "....": "H",
"..": "I", ".---": "J", "-.-": "K", ".-..": "L",
"--": "M", "-.": "N", "---": "O", ".--.": "P",
"--.-": "Q", ".-.": "R", "...": "S", "-": "T", "..-": "U", "...-": "V",
".--": "W", "-..-": "X", "-.--": "Y", "--..": "Z"}

nomorse = input("Enter your Morse code here:")
nomorse_list = nomorse.split() #this splits the string up wherever there is a space
not_morse = []
morse = True    #The code is morse (so far)
for letter in nomorse_list:
    eng_letter = False
    for key in morse_eng_dict.keys():   #for each of the morse code letters in the dictionary
        if letter == key:
            eng_letter = morse_eng_dict[key]
    if eng_letter: #if a letter was found that corresponds
        not_morse.append(eng_letter)
    else:
        print("Input is not valid morse code.")
        morse = False
if morse == True:
    string = "".join(not_morse) #joining the string together (without spaces in between)
    print(string)

Answer 3

对于任何 dictionary = {'.-': 'a'} dictionary['.-'] 会给你 'a' dictionary.get('.-') 也会给你一个 'a' 字典的索引是字符串、任何字符串和 '.'不同于'.-'

'.','.-','...','-.--'

btw morse 是一个以 E = left.node 和 T = right.node ...
