Hướng dẫn can python open docx files? - python có thể mở tệp docx không?

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

Đặc điểm này là một trong những mạnh mẽ. Rất nhiều tài liệu trông được xác định bởi các phần còn lại khi bạn xóa tất cả các nội dung. Những thứ như phong cách và tiêu đề trang và chân trang được chứa tách biệt với nội dung chính, cho phép bạn đặt nhiều tùy chỉnh trong tài liệu bắt đầu của bạn sau đó xuất hiện trong tài liệu bạn sản xuất.

Hãy cùng bước đi qua các bước để tạo một tài liệu một ví dụ tại một thời điểm, bắt đầu với hai trong số những điều chính bạn có thể làm với một tài liệu, mở nó và lưu nó.

Mở một tài liệu

Cách đơn giản nhất để bắt đầu là mở một tài liệu mới mà không cần chỉ định một tệp để mở:

from docx import Document

document = Document()
document.save('test.docx')

Điều này tạo ra một tài liệu mới từ mẫu mặc định tích hợp và lưu nó không thay đổi vào một tệp có tên ‘test.docx. Cái gọi là mẫu mặc định, thực sự chỉ là một tệp Word không có nội dung, được lưu trữ với gói

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

Thực sự mở một tài liệu

Nếu bạn muốn kiểm soát nhiều hơn đối với tài liệu cuối cùng hoặc nếu bạn muốn thay đổi một tài liệu hiện có, bạn cần mở một tài liệu bằng tên tệp:

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

Những điều cần lưu ý:

• Bạn có thể mở bất kỳ từ 2007 hoặc sau đó tệp theo cách này (các tệp .doc từ Word 2003 và trước đó đã giành được công việc). Mặc dù bạn có thể không thể thao túng tất cả các nội dung, nhưng bất cứ thứ gì đã có trong đó sẽ tải và tiết kiệm tốt. Bộ tính năng vẫn đang được xây dựng, vì vậy bạn không thể thêm hoặc thay đổi những thứ như tiêu đề hoặc chú thích, nhưng nếu tài liệu có chúng

  f = open('foobar.docx', 'rb')
  document = Document(f)
  f.close()
  
  # or
  
  with open('foobar.docx', 'rb') as f:
      source_stream = StringIO(f.read())
  document = Document(source_stream)
  source_stream.close()
  ...
  target_stream = StringIO()
  document.save(target_stream)
  

  6 đủ lịch sự để để chúng một mình và đủ thông minh để lưu chúng mà không thực sự hiểu chúng là gì .
• Nếu bạn sử dụng cùng một tên tệp để mở và lưu tệp,

  f = open('foobar.docx', 'rb')
  document = Document(f)
  f.close()
  
  # or
  
  with open('foobar.docx', 'rb') as f:
      source_stream = StringIO(f.read())
  document = Document(source_stream)
  source_stream.close()
  ...
  target_stream = StringIO()
  document.save(target_stream)
  

  6 sẽ ngoan ngoãn ghi đè lên tệp gốc mà không cần nhìn trộm. Bạn muốn đảm bảo rằng, những gì bạn dự định.

Mở một tài liệu giống như tệp

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

Được rồi, vì vậy bạn đã mở một tài liệu và khá chắc chắn rằng bạn có thể lưu nó ở đâu đó sau này. Bước tiếp theo là có được một số nội dung trong đó

Các tài liệu PDF và Word là các tệp nhị phân, giúp chúng phức tạp hơn nhiều so với các tệp PlainText. Ngoài văn bản, họ lưu trữ rất nhiều thông tin phông chữ, màu sắc và bố cục. Nếu bạn muốn các chương trình của mình đọc hoặc ghi vào PDF hoặc tài liệu từ, bạn sẽ cần phải làm nhiều hơn là chỉ cần chuyển tên tệp của họ sang

   >>> import PyPDF2
   >>> pdfFileObj = open('meetingminutes.pdf', 'rb')
   >>> pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
❶ >>> pdfReader.numPages
   19
❷ >>> pageObj = pdfReader.getPage(0)
❸ >>> pageObj.extractText()

May mắn thay, có các mô -đun Python giúp bạn dễ dàng tương tác với PDF và tài liệu từ. Chương này sẽ bao gồm hai mô-đun như vậy: PYPDF2 và Python-docx.

Tài liệu PDF

PDF là viết tắt của định dạng tài liệu di động và sử dụng tiện ích mở rộng tệp .pdf. Mặc dù PDF hỗ trợ nhiều tính năng, chương này sẽ tập trung vào hai điều bạn sẽ làm thường xuyên nhất với chúng: đọc nội dung văn bản từ PDF và chế tạo các tệp PDF mới từ các tài liệu hiện có. stands for Portable Document Format and uses the .pdf file extension. Although PDFs support many features, this chapter will focus on the two things you’ll be doing most often with them: reading text content from PDFs and crafting new PDFs from existing documents.

Mô -đun mà bạn sẽ sử dụng để làm việc với PDFS là PYPDF2. Để cài đặt nó, chạy

Trích xuất văn bản từ PDFS

PYPDF2 không có cách trích xuất hình ảnh, biểu đồ hoặc phương tiện khác từ các tài liệu PDF, nhưng nó có thể trích xuất văn bản và trả về nó dưới dạng chuỗi Python. Để bắt đầu tìm hiểu cách thức hoạt động của PYPDF2, chúng tôi sẽ sử dụng nó trên ví dụ PDF được hiển thị trong Hình & NBSP; 13-1.

PYPDF2 không cho phép bạn chỉnh sửa trực tiếp PDF. Thay vào đó, bạn phải tạo một tệp PDF mới và sau đó sao chép nội dung từ một tài liệu hiện có. Các ví dụ trong phần này sẽ tuân theo cách tiếp cận chung này:

1. Mở một hoặc nhiều tệp PDF hiện có (PDF nguồn) vào các đối tượng

      >>> import PyPDF2
      >>> pdfFileObj = open('meetingminutes.pdf', 'rb')
      >>> pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
   ❶ >>> pdfReader.numPages

Trang quay

Các trang của PDF cũng có thể được xoay theo gia số 90 độ với các phương pháp

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

   >>> import PyPDF2
   >>> minutesFile = open('meetingminutes.pdf', 'rb')
   >>> pdfReader = PyPDF2.PdfFileReader(minutesFile)
❶ >>> page = pdfReader.getPage(0)
❷ >>> page.rotateClockwise(90)
   {'/Contents': [IndirectObject(961, 0), IndirectObject(962, 0),
   --snip--
   }
   >>> pdfWriter = PyPDF2.PdfFileWriter()
   >>> pdfWriter.addPage(page)
❸ >>> resultPdfFile = open('rotatedPage.pdf', 'wb')
   >>> pdfWriter.write(resultPdfFile)
   >>> resultPdfFile.close()
   >>> minutesFile.close()

Ở đây chúng tôi sử dụng

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

PDF kết quả sẽ có một trang, xoay 90 độ theo chiều kim đồng hồ, như trong Hình & NBSP; 13-2. Các giá trị trả về từ

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

Lớp phủ trang

PYPDF2 cũng có thể phủ lên nội dung của một trang trên một trang khác, rất hữu ích cho việc thêm logo, dấu thời gian hoặc hình mờ vào một trang. Với Python, nó rất dễ dàng để thêm hình mờ vào nhiều tệp và chỉ vào các trang chương trình của bạn chỉ định.

Tải xuống watermark.pdf từ http://nostarch.com/automatestuff/ và đặt pdf vào thư mục làm việc hiện tại cùng với meetminutes.pdf. Sau đó nhập phần sau vào vỏ tương tác:watermark.pdf from http://nostarch.com/automatestuff/ and place the PDF in the current working directory along with meetingminutes.pdf. Then enter the following into the interactive shell:

   >>> import PyPDF2
   >>> minutesFile = open('meetingminutes.pdf', 'rb')
❷ >>> pdfReader = PyPDF2.PdfFileReader(minutesFile)

Dự án: Kết hợp các trang chọn lọc từ nhiều tệp PDF

Giả sử bạn có công việc nhàm chán là hợp nhất vài chục tài liệu PDF vào một tệp PDF duy nhất. Mỗi người trong số họ có một trang bìa là trang đầu tiên, nhưng bạn không muốn trang bìa được lặp lại trong kết quả cuối cùng. Mặc dù có rất nhiều chương trình miễn phí để kết hợp PDF, nhiều trong số chúng chỉ đơn giản hợp nhất toàn bộ các tệp với nhau. Hãy để viết một chương trình Python để tùy chỉnh trang bạn muốn trong PDF kết hợp.

Ở cấp độ cao, ở đây, những gì chương trình sẽ làm:

• Tìm tất cả các tệp PDF trong thư mục làm việc hiện tại.

• Sắp xếp tên tệp để các tệp PDF được thêm vào theo thứ tự.

• Viết từng trang, không bao gồm trang đầu tiên, của mỗi tệp PDF vào tệp đầu ra.

  Về mặt thực hiện, mã của bạn sẽ cần phải thực hiện như sau:

• Gọi

  document = Document('existing-document-file.docx')
  document.save('new-file-name.docx')
  

  40 để tìm tất cả các tệp trong thư mục làm việc và xóa bất kỳ tệp không PDF nào.

• Gọi Phương thức danh sách Python từ

  document = Document('existing-document-file.docx')
  document.save('new-file-name.docx')
  

  41 để bảng chữ cái tên tệp.

• Tạo một đối tượng

     >>> import PyPDF2
     >>> minutesFile = open('meetingminutes.pdf', 'rb')
  ❷ >>> pdfReader = PyPDF2.PdfFileReader(minutesFile)
  ❷ >>> minutesFirstPage = pdfReader.getPage(0)
  ❸ >>> pdfWatermarkReader = PyPDF2.PdfFileReader(open('watermark.pdf', 'rb'))
  ❹ >>> minutesFirstPage.mergePage(pdfWatermarkReader.getPage(0))
  ❺ >>> pdfWriter = PyPDF2.PdfFileWriter()
  ❻ >>> pdfWriter.addPage(minutesFirstPage)
  
  ❼ >>> for pageNum in range(1, pdfReader.numPages):
             pageObj = pdfReader.getPage(pageNum)
             pdfWriter.addPage(pageObj)
     >>> resultPdfFile = open('watermarkedCover.pdf', 'wb')
     >>> pdfWriter.write(resultPdfFile)
     >>> minutesFile.close()
     >>> resultPdfFile.close()

  0 cho PDF đầu ra.

• Vòng lặp qua mỗi tệp PDF, tạo một đối tượng

     >>> import PyPDF2
     >>> pdfFileObj = open('meetingminutes.pdf', 'rb')
     >>> pdfReader = PyPDF2.PdfFileReader(pdfFileObj)

  8 cho nó.

• Vòng lặp qua mỗi trang (ngoại trừ trang đầu tiên) trong mỗi tệp PDF.

• Thêm các trang vào PDF đầu ra.

• Viết PDF đầu ra vào một tệp có tên allminutes.pdf.allminutes.pdf.

Đối với dự án này, hãy mở một cửa sổ Trình chỉnh sửa tệp mới và lưu nó dưới dạng CombinePdfs.py.combinePdfs.py.

Bước 1: Tìm tất cả các tệp PDF

Đầu tiên, chương trình của bạn cần có một danh sách tất cả các tệp với tiện ích mở rộng .pdf trong thư mục làm việc hiện tại và sắp xếp chúng. Làm cho mã của bạn trông giống như sau:.pdf extension in the current working directory and sort them. Make your code look like the following:

   #! python3
   # combinePdfs.py - Combines all the PDFs in the current working directory into
   # into a single PDF.

❶ import PyPDF2, os

   # Get all the PDF filenames.
   pdfFiles = []
   for filename in os.listdir('.'):
       if filename.endswith('.pdf'):
❷         pdfFiles.append(filename)
❸ pdfFiles.sort(key=str.lower)

❹ pdfWriter = PyPDF2.PdfFileWriter()

   # TODO: Loop through all the PDF files.

   # TODO: Loop through all the pages (except the first) and add them.

   # TODO: Save the resulting PDF to a file.

Sau dòng Shebang và nhận xét mô tả về những gì chương trình làm, mã này nhập các mô -đun

Nếu bạn không có Word, LibreOffice Writer và OpenOffice Writer đều là các ứng dụng thay thế miễn phí cho Windows, OS X và Linux có thể được sử dụng để mở các tệp .docx. Bạn có thể tải xuống chúng từ https://www.libreoffice.org và http://openoffice.org, tương ứng. Tài liệu đầy đủ cho Python-docx có sẵn tại https://python-docx.readthedocs.org/. Mặc dù có một phiên bản của Word cho OS X, chương này sẽ tập trung vào Word cho Windows..docx files. You can download them from https://www.libreoffice.org and http://openoffice.org, respectively. The full documentation for Python-Docx is available at https://python-docx.readthedocs.org/. Although there is a version of Word for OS X, this chapter will focus on Word for Windows.

Với Python-DOCX, các chương trình Python của bạn giờ đây sẽ có thể đọc văn bản từ tệp .docx và sử dụng nó giống như bất kỳ giá trị chuỗi nào khác..docx file and use it just like any other string value.

Nhận toàn bộ văn bản từ tệp .docx

Nếu bạn chỉ quan tâm đến văn bản, không phải thông tin kiểu dáng, trong tài liệu Word, bạn có thể sử dụng hàm

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

Hàm

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

Chương trình ReadDocx.py có thể được nhập như bất kỳ mô -đun nào khác. Bây giờ nếu bạn chỉ cần văn bản từ một tài liệu Word, bạn có thể nhập những điều sau:readDocx.py program can be imported like any other module. Now if you just need the text from a Word document, you can enter the following:

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

Bạn cũng có thể điều chỉnh

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

Để thêm một không gian kép ở giữa các đoạn, hãy thay đổi mã cuộc gọi

f = open('foobar.docx', 'rb')
document = Document(f)
f.close()

# or

with open('foobar.docx', 'rb') as f:
    source_stream = StringIO(f.read())
document = Document(source_stream)
source_stream.close()
...
target_stream = StringIO()
document.save(target_stream)

document = Document('existing-document-file.docx')
document.save('new-file-name.docx')

Như bạn có thể thấy, chỉ cần một vài dòng mã để viết các chức năng sẽ đọc tệp .docx và trả về một chuỗi nội dung của nó theo ý thích của bạn..docx file and return a string of its content to your liking.

Đoạn đồ tạo kiểu và các đối tượng chạy

Trong Word for Windows, bạn có thể thấy các kiểu bằng cách nhấn Ctrl-Alt-Shift-S để hiển thị khung kiểu kiểu, trông giống như Hình & NBSP; 13-5. Trên OS X, bạn có thể xem ngăn Kiểu bằng cách nhấp vào mục menu Xem.CTRL-ALT-SHIFT-S to display the Styles pane, which looks like Figure 13-5. On OS X, you can view the Styles pane by clicking the View▸Styles menu item.

Hình & nbsp; 13-5. & Nbsp; hiển thị khung kiểu bằng cách nhấn ________ 231-S trên Windows.

Word và các bộ xử lý Word khác sử dụng các kiểu để giữ trình bày trực quan của các loại văn bản tương tự nhất quán và dễ thay đổi. Ví dụ, có lẽ bạn muốn thiết lập các đoạn văn trong văn bản 11 điểm, lần New Roman, vô lý bên trái, rách rưới. Bạn có thể tạo một kiểu với các cài đặt này và gán nó cho tất cả các đoạn văn. Sau đó, nếu sau đó bạn muốn thay đổi cách trình bày tất cả các đoạn văn trong tài liệu, bạn chỉ có thể thay đổi kiểu và tất cả các đoạn đó sẽ được tự động cập nhật.

Đối với các tài liệu từ, có ba loại kiểu: Kiểu đoạn có thể được áp dụng cho các đối tượng
