Question

我试图写一个一致性程序，我试图让shell打开一个文件，阅读它，并解释内容是什么。然后我希望它按字母顺序打印出单词，以及单词相对于文本的位置。到目前为止我有这个：

到目前为止，代码按字母顺序正确地给出了单词;但是，它并没有给我正确的位置。我对python有些新意，所以如果你能尝试保持它有点基础，那将是值得赞赏的。我还想保持标点符号，使其更加独特。＆＃34;

据我所知，您关注文件中存在的单词的实际位置，同时您希望按字母顺序打印单词。您可以使用以下代码：

请注意，我们总是会对每个单词进行计数，这是存储该单词位置的列表的长度。

# allwords is a dictionary which uses word as the key and the list of position of the word in the file as the value.
# The position will be recored as (line_number, word_number) tuple where word_number is position of the word in that particular line.

allwords = {}

# Get the index of the line as well.
for lineno,line in enumerate(handle.readlines()):

    words = line.split()

    # Get the word index as well.
    for wordno,w in enumerate(words):

        w = w.lower()

        # Make the position tuple and append in the list of appearances for that particular word.
        position = (lineno+1, wordno+1)

        if w not in allwords.keys():

            allwords[w] = []

        allwords[w].append(position)



for key in sorted(allwords.keys()):
    print(key + " appeared " + str(len(allwords[key])) + " number of times and positions are:")
    for tup in allwords[key]:
        print(tup)

python中的一致性。按字母顺序
