Answer 1

我认为你可以使用pyPdf Python库（http://pybrary.net/pyPdf/）。 的网页此代码显示号码其中包括所需的字：

from pyPdf import PdfFileReader 

input = PdfFileReader(file("YourPDFFile.pdf", "rb")) 

numberOfPages = input.getNumPages() 

i = 1 
while i < numberOfPages: 
    oPage = input.getPage(i) 
    text = oPage.extractText() 
    text.encode('utf8', 'ignore') 
    if text.find('What are you looking for') != -1: 
     print i 
    i += 1 

相同，但与Python 3

from pyPdf import PdfFileReader 

input = PdfFileReader(open("YourPDFFile.pdf", "rb")) 

numberOfPages = input.getNumPages() 

i = 1 
while i < numberOfPages: 
    oPage = input.getPage(i) 
    text = oPage.extractText() 
    text.encode('utf8', 'ignore') 
    if text.find('What are you looking for') != -1: 
     print(i) 
    i += 1
