从中提取文本后, Python可以读取PDF文件并打印出内容。为此,我们必须首先安装所需的模块PyPDF2 。以下是安装模块的命令。您应该已经在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可用的方法读取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.

阅读多页

要读取包含多页的pdf文件并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,我们有两页的PDF文件。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,我们得到以下输出-

Page No - 1
