處理PDF

Python可以從中提取文本后讀取PDF文件并打印出內(nèi)容。 為此，必須首先安裝所需的模塊PyPDF2，以下是安裝模塊的命令。應該已經(jīng)在python環(huán)境中安裝了pip。

pip install pypdf2

成功安裝此模塊后，可以使用模塊中提供的方法讀取PDF文件。

import PyPDF2

pdfName = 'path\Yiibaipoint.pdf'
read_pdf = PyPDF2.PdfFileReader(pdfName)
page = read_pdf.getPage(0)
page_content = page.extractText()
print page_content

當運行上面的程序時，我們得到以下輸出 -

Yiibai 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.

讀取多個頁面

要閱讀包含多個頁面的pdf并使用頁碼打印每個頁面，使用帶有getPageNumber()函數(shù)的循環(huán)。 在下面的例子中有兩個頁面的PDF文件。內(nèi)容在兩個單獨的頁面標題下打印。

import PyPDF2

pdfName = 'Path\Yiibaispoint2.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

執(zhí)行上面示例代碼，得到以下結(jié)果 -

Page No - 1
