Python - 处理 PDF

• 

  简述

  Python 可以读取 PDF 文件并在从中提取文本后打印出内容。为此，我们必须首先安装所需的模块，即PyPDF2. 下面是安装模块的命令。你应该已经在你的 python 环境中安装了 pip。

  
  pip install pypdf2
  

  成功安装此模块后，我们可以使用模块中提供的方法读取 PDF 文件。

  
  import PyPDF2
  pdfName = 'path\Tutorialspoint.pdf'
  read_pdf = PyPDF2.PdfFileReader(pdfName)
  page = read_pdf.getPage(0)
  page_content = page.extractText()
  print page_content
  

  当我们运行上述程序时，我们得到以下输出 -

  
  CAINIAOYA originated from the idea that there exists a class of readers who respond better
  to online content and prefer to learn new skills at their own pace from the comforts of their 
  drawing rooms.
   
  The journey commenced with a single tutorial on HTML in 2006 and elated by the response 
  it generated, we worked our way to adding fresh tutorials to our repository which now 
  proudly flaunts a wealth of tutorials and allied articles on topics ranging from programming
  languages to web designing to academics and much more.

  阅读多页

  要阅读具有多页的 pdf 并使用页码打印每一页，我们使用带有 getPageNumber() 函数的 a 循环。在下面的示例中，我们的 PDF 文件有两页。内容打印在两个单独的页面标题下。

  
  import PyPDF2
  pdfName = 'Path\Tutorialspoint2.pdf'
  read_pdf = PyPDF2.PdfFileReader(pdfName)
  for i in xrange(read_pdf.getNumPages()):
      page = read_pdf.getPage(i)
      print 'Page No - ' + str(1+read_pdf.getPageNumber(page))
      page_content = page.extractText()
      print page_content
  

  当我们运行上述程序时，我们得到以下输出 -

  
  Page No - 1
  CAINIAOYA originated from the idea that there exists a class of readers who respond better to
  online content and prefer to learn new skills at their own pace from the comforts of their drawing 
  rooms. 
  Page No - 2
   
  The journey commenced with a single tutorial on HTML in 2006 and elated by the response it 
  generated, we worked our way to adding fresh tutorials to our repository which now proudly flaunts 
  a wealth of tutorials and allied articles on topics ranging from p
  rogramming languages to web 
  designing to academics and much more.
