Come leggere il file PDF riga per riga usando Python

Python può leggere i file PDF e stamparne il contenuto dopo averne estratto il testo. Per questo dobbiamo prima installare il modulo richiesto che è PyPDF2. Di seguito è riportato il comando per installare il modulo. You should have pip already installed in your python environment.

1. pip install pypdf2 

On successful installation of this module we can read PDF files using the methods available in the module.

Reading Single Page

1. import PyPDF2 
2.  
3. pdfName = 'path\xyz.pdf' 
4. read_pdf = PyPDF2.PdfFileReader(pdfName) 
5. page = read_pdf.getPage(0) 
6. page_content = page.extractText() 
7. print page_content 

When we run the above program, we get the output

Reading Multiple Pages

To read a pdf with multiple pages and print each of the page with a page number we use the a loop with getPageNumber() function. Nell'esempio seguente abbiamo il file PDF che ha due pagine. The contents are printed under two separate page headings.

1. import PyPDF2 
2.  
3. pdfName = 'Path\xyz2.pdf' 
4. read_pdf = PyPDF2.PdfFileReader(pdfName) 
5.  
6. for i in xrange(read_pdf.getNumPages()): 
7. page = read_pdf.getPage(i) 
8. print 'Page No - ' + str(1+read_pdf.getPageNumber(page)) 
9. page_content = page.extractText() 
10. print page_content
