Read mail attachment & that use it for pyPdf2: PdfFileReader

Question

I'm just trying to read mail attachment (PDF file attached) in memory so that i can use that it for pyPdf2

Here is the basic code,

from pyPdf2 import PdfFileReader
.
.
for attachment in message.attachments:
   attachment_name = attachment[0].decode()
   attachment_content = attachment[1].decode()

Here i just wanted to know that how much pages (page count) attached pdf has using attachment_content & attachment_name variable,

For more info, There is a method in pyPdf2, using that we can get pages count.

pdf_instance = PdfFileReader(file(file_path, "rb")) #But i'm stuck here, how to specify here *file_path* & not able to use that *attachment_content* & *attachment_name* varible
pdf_instance.getNumPages()

Any body can help me out here to use PdfFileReader

Thanks.

you probably want to use a StringIO object to "fake" a file for PdfFileReader to use. — Paul Collingwood, Aug 12 '14 at 08:11
@PaulCollingwood: Could you please elaborate it through example? that would really help me to understand clearly. — Niks Jain, Aug 12 '14 at 09:30

Perhaps something like (untested):

import StringIO

output = StringIO.StringIO()
output.write(attachment[0].decode())

df_instance = PdfFileReader(file(output, "rb"))

What is StringIO in python used for in reality?

Even if the above is not quite right, you should be able to make it work after reading a StringIO tutorial or two.

Do you want to give this a Python 3 update? – Martin Thoma Dec 20 '22 at 22:46
