Python 处理PDF

Python可以读取PDF文件并从中提取文本后打印内容。为此，我们首先要安装所需的模块是 PyPDF2 。以下是安装该模块的命令。您的Python环境中应该已经安装了pip。

pip install pypdf2

安装成功后，我们可以使用模块中可用的方法来读取 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

运行上面的程序时，我们得到以下输出 –

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.

阅读多个页面

要阅读带有多个页面并打印每个页面的页面编号的pdf，我们使用一个循环并配合getPageNumber()函数。在下面的示例中，我们有一个包含两个页面的PDF文件。内容将分别打印在两个独立的页面标题下。

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，我们得到以下输出：

Page No - 1
