python从文本fi将两个空格解释为一个

Question

我想做一个程序从文本文件中翻译摩尔斯电码。从理论上讲，这应该是相当容易的，但问题是，我觉得文本文件的格式有点傻（它的学校工作，所以不能改变这一点）。我的意思是，在文件中，一个空格分隔两个字符（如-. ---），但两个空格等于一个单词的结尾（所以在翻译文本中是空格）。像这样：.--. .-.. . .- ... . .... . .-.. .--. .-.-.- 这就是我所拥有的，但它给了我没有空格的翻译文本。你知道吗

    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)

我也不知道如何截取换行（\n）。你知道吗

Answer 1

在两个空格上拆分，首先得到每行中的单词列表，然后可以在一个空格上拆分单词，得到字符以供翻译人员使用

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))

你为什么不在两个空格上分开得到单词，然后在空格上得到字符？比如：

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，所有这些都假设您的translatordict有正确的映射。你知道吗
