Python - 处理 PDF

Python 可以读取 PDF 文件并在从中提取文本后打印出内容。 为此，我们必须先安装所需的模块 PyPDF2。 下面是安装模块的命令。 你的 python 环境中应该已经安装了 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阅读 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

当我们运行上面的程序时，得到以下输出 −

Tutorials Point 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.

读取多个页面

要读取包含多页的 pdf 并使用页码打印每个页面，我们使用带有 getPageNumber() 函数的循环。 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

当我们运行上面的程序时，得到以下输出 −

Page No - 1
