Try pdfminer:
试试pdfminer：
from pdfminer.pdfparser import PDFParser
from pdfminer.pdfdocument import PDFDocument
fp = open('diveintopython.pdf', 'rb')
parser = PDFParser(fp)
doc = PDFDocument(parser)
print(doc.info) # The "Info" metadata
Here's the output:
这是输出：

Morten Zilmer 指出：pyPdf主页说它不再维护。
I have implemented this using pyPdf. Please see the sample code below.
from pyPdf import PdfFileReader
pdf_toread = PdfFileReader(open("doc2.pdf", "rb"))
pdf_info = pdf_toread.getDocumentInfo()
print(str(pdf_info))
Output:
输出：
{'/Title': u'Microsoft Word - Agnico-Eagle - Complaint (00040197-2)', '/CreationDate': u"D:20111108111228-05'00'", '/Producer': u'Acrobat Distiller 10.0.0 (Windows)', '/ModDate': u"D:20111108112409-05'00'", '/Creator': u'PScript5.dll Version 5.2.2', '/Author': u'LdelPino'}

For Python 3 and new pdfminer (pip install pdfminer3k):
对于 Python 3 和新的 pdfminer（pip install pdfminer3k）：
import os
from pdfminer.pdfparser import PDFParser
from pdfminer.pdfparser import PDFDocument
fp = open("foo.pdf", 'rb')
parser = PDFParser(fp)
doc = PDFDocument(parser)
parser.set_document(doc)
doc.set_parser(parser)
if len(doc.info) > 0:
info = doc.info[0]
print(info)
