Python 3 - 如何删除 line/paragraph 中断

Question

from docx import Document

alphaDic = ['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','!','?','.','~',',','(',')','$','-',':',';',"'",'/']

while docIndex < len(doc.paragraphs):
    firstSen = doc.paragraphs[docIndex].text
    rep_dic = {ord(k):None for k in alphaDic + [x.upper() for x in alphaDic]}
    translation = (firstSen.translate(rep_dic))
    removeSpaces = " ".join(translation.split())
    removeLineBreaks = removeSpaces.replace('\n','')
    doc.paragraphs[docIndex].text = removeLineBreaks

    docIndex +=1

我正在尝试从文档中删除换行符，但它不起作用。我还在收到

Hello


There

而不是

Hello
There

Answer 1

由于 readlines 可以读取任何类型的文本文件，您可以打开文件重写您想要的行并忽略您不想使用的行。

"""example"""

file = open("file name", "w")
for line in file.readlines():
    if (line != ''):
        file.write(line)

Answer 2

该软件包附带一个提取文本的 example program。

也就是说，我认为您的问题源于您试图对段落进行操作。但是段落之间的分隔是换行符发生的地方。所以即使你用空字符串（''）替换一个程序，它的末尾仍然会添加一个换行符。

您应该采用示例程序的方法，并进行自己的格式化，或者您应该确保删除可能位于 "full" 段落之间的任何虚假 "empty" 段落有 ("Hello", "", "There") -> ("Hello", "There").

Answer 3

我想你想要做的是去掉一个空段落。以下函数可能会有所帮助，它会删除您不想要的某个段落：

def delete_paragraph(paragraph):
    p = paragraph._element
    p.getparent().remove(p)
    p._p = p._element = None

在您的代码中，您可以检查翻译是否等于 ''，如果是，则调用 delete_paragraph 函数，因此您的代码如下：

while docIndex < len(doc.paragraphs):
    firstSen = doc.paragraphs[docIndex].text
    rep_dic = {ord(k):None for k in alphaDic + [x.upper() for x in alphaDic]}
    translation = (firstSen.translate(rep_dic))
    if translation != '':
        doc.paragraphs[docIndex].text = translation 
    else:
        delete_paragraph(doc.paragraphs[docIndex])
        docIndex -=1 # go one step back in the loop because of the deleted index

    docIndex +=1
