如何在文本文件中每隔1000個單詞添加\\ n換行符？

Question

好了，這就是問題。 我有一些文本文件，其中包含14,000多個單詞，但它們都排成一行，如果您使用的編輯器沒有自動換行功能，則無法讀取該文本文件。 因此，我想在至少1000個單詞之后以及下次出現"."向文件添加returns或newline "." 。 我的第一個想法是對行進行計數，然后將其加起來，並在達到1000時插入一個\\n字符，但所有字符都在一行上。 這使事情變得更加困難，而且我一直無法找到一種方法來實現自己想要的目標。 如果沒有我，我本人將自己遍歷文本文件並添加換行符。 這違背了我只運行python腳本自動為我完成目標的目標。 這可能嗎？ 還是我為這樣的想法而瘋狂？ 預先感謝您提供的任何幫助！ 我在下面提供了各種嘗試來做到這一點。

在這種嘗試中，代碼可以按預期工作，但是打印出的Word Count is over 1000大約14倍而不是它。 因為，此文本文件的字數是14,000左右。 它只打印一次，因為只有一行可以讀取。

text_file = "textfile.txt"
numLines = 0
numWords = 0
numChars = 0

with open(text_file, 'r') as file:
for line in file:
    wordsList = line.split()
    numLines +=1
    numWords += len(wordsList)
    numChars += len(line)
    if numWords > 1000:
        print("Word Count is over 1000.")

在下一次嘗試中，我沒有類似之處，但仍然得到與上述相同的結果。 \\n\\n\\n\\n不會看到它大約14次寫入文本文件，而是僅在文件末尾發生一次。

def oldWordCounter(input_file):
    word_count = 0

    with open(input_file, 'r') as f:
        for line in f:
            word_count = len(line.split(' '))
            print("Word count = %s \n" % word_count)

    if word_count > 1000: 
        with open(input_file, 'a') as f:
            f.write("\n\n\n\n")

我確定我只是缺少一些簡單的東西，但我對python還是很陌生。 即使殺了我在這里問一個問題。 我盡全力以赴，似乎再也沒有辦法。 因此，再次感謝您在此問題上可以提供的任何幫助！

同樣在下面，我提供了下一個周期發生后計划添加換行符的方式。 不知道這是否有幫助，但可能會幫助您了解我想完成的更多事情。

def splitOnPeriod(input_file):
with open(input_file,"r") as f:
    for line in f:
        searchPhrase = "."
        if searchPhrase in line:
            file = open(input_file, "a")
            file.write("\n\n\n\n")
            print("found it\n")

Answer 1

這段代碼每隔1000行就會拆分一次，在達到時會重置. ：

words = s.split()
new_text = ""
word_count = 0
for word in words:
    new_text += word + " "
    word_count += 1
    if word_count == 1000 or "." in word:
        new_text += "\n"
        word_count = 0

其中s是從文件讀取的字符串。 之后，只需將new_text寫入文件即可。

Answer 2

讀取所有單詞以列出並在每千個單詞或帶有句點的單詞后附加“ \\ n”以歸檔。

AllWords = []
for line in open("data_words.txt"):
    row = line.split(' ')
    AllWords+=list(row)

line_breaker=1000
i=1
with open("/home/kiran/km/km_hadoop/data/data_wordcount_op.txt", 'a') as file:
    for word in AllWords:
        if("." in word or i==line_breaker):
            file.write(word.strip('\n')+"\n")
            i=0
        else:
            file.write(word.strip('\n')+" ")

        i+=1

為了回答您的第一個問題，我定義了一個linewrapper函數，該函數需要一個文件和所需的換行長度。 使用模運算符，我們將迭代器除以wrap_length減一，因為索引從0開始。模運算符使我們能夠確定它是否可以被100整除。例如，如果wrap_length為97並且i為96，我們將得到余數的值不是0。如果沒有余數，那么該值將為0。我們需要檢查i是否為0，因為0除以0不會得到余數。 您可以在此處閱讀有關如何應用該運算符的更多信息： https : //docs.python.org/3.3/reference/expressions.html#binary-arithmetic-operations

def linewrapper(input_file, wrap_length):
    with open(input_file, 'r') as input_file, open('output.txt', 'w') as output_file:
        for line in input_file:
            words = line.split()
            for i in range(0, len(words)):
                output_file.write('%s ' % words[i])
                if i != 0 and i % (wrap_length - 1) == 0:
                    output_file.write("\n")

linewrapper('input.txt', 100)
