Python - 处理PDF

Python可以从中提取文本后读取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提供的方法读取PDF文件。

import PyPDF2

pdfName = 'path\codingdict.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.

阅读多个页面

要阅读包含多个页面的pdf并使用页码打印每个页面，我们使用带有getPageNumber（）函数的循环。在下面的例子中我们有两个页面的PDF文件。内容在两个单独的页面标题下打印。

import PyPDF2

pdfName = 'Path\codingdict2.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
