Question

我正在尝试制作一个从文本文件中翻译莫尔斯电码的程序。理论上它应该很容易但问题是我发现文本文件的格式有点傻（它的学校工作所以不能改变它）。我的意思是，在文件中，一个空格分隔两个字符（如此-. ---），但两个空格等于一个单词的结尾（因此翻译文本中的空格）。像这样：.--. .-.. . .- ... . .... . .-.. .--. .-.-.- 这就是我所拥有的，但它为我提供了没有空格的翻译文本。

    translator = {} #alphabet and the equivalent code, which I got from another file 
    message = []
    translated = ("")
    msg_file = open(msg.txt,"r")
    for line in msg_file:
        line = line.rstrip()
        part = line.rsplit(" ")
        message.extend(part)
    for i in message:
        if i in translator.keys():
            translated += (translator[i])
    print(translated)

我也不知道如何拦截换行（\ n）。

为什么不分开两个空格来获取单词，然后在空格中获取字符？类似的东西：

translated = ""  # store for the translated text
with open("msg.txt", "r") as f:  # open your file for reading
    for line in f:  # read the file line by line
        words = line.split("  ")  # split by two spaces to get our words
        parsed = []  # storage for our parsed words
        for word in words:  # iterate over the words
            word = []  # we'll re-use this to store our translated characters
            for char in word.split(" "):  # get characters by splitting and iterate over them
                word.append(translator.get(char, " "))  # translate the character
            parsed.append("".join(word))  # join the characters and add the word to `parsed`
        translated += " ".join(parsed)  # join the parsed words and add them to `translated`
        # uncomment if you want to add new line after each line of the file:
        # translated += "\n"
print(translated)  # print the translated string
# PLEASE HELP!

当然，所有这一切都假设你的translator dict有正确的映射。

首先在双倍空格中拆分以获取每行中的单词列表，然后您可以在单个空格中拆分单词以获取字符以便为翻译人员提供

translator = {} #alphabet and the equivalent code, which I got from another file 
message = []
translated = ("")
with open('msg.txt',"r") as msg_file:
    for line in msg_file:
        line = line.strip()
        words = line.split('  ')
        line = []
        for word in words:
            characters = word.split()
            word = []
            for char in characters:
                word.append(translator[char])
            line.append(''.join(word))
        message.append(' '.join(line))

print('\n'.join(message))

python - 将两个空格解释为文本文件中的一个空格
