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

# Date : 2020-08-23
import PyPDF2
pdfName = 'Path\test.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
执行上面示例代码，得到以下结果 -
