Check unread count of Gmail messages with Python

Question

How can I check the number of unread Gmail message in my inbox with a short Python script? Bonus points for retrieving the password from a file.

Answer 1

Once you are logged in (do this manually or with gmail.py) you should use the feed.

It is located here: http://mail.google.com/mail/feed/atom

It is the way Google does it. Here is a link to their js chrome extension: http://dev.chromium.org/developers/design-documents/extensions/samples/gmail.zip

You will then be able to parse xml that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<feed version="0.3" xmlns="http://purl.org/atom/ns#">
<title>Gmail - Inbox for yourmail@gmail.com</title>
<tagline>New messages in your Gmail Inbox</tagline>
<fullcount>142</fullcount>

Answer 2

Use Gmail.py

file = open("filename","r")
usr = file.readline()
pwd = file.readline()
gmail = GmailClient()
gmail.login(usr, pwd)
unreadMail = gmail.get_inbox_conversations(is_unread=True)
print unreadMail

Gets login information from a text file assuming the login name and password are on separate lines.

Answer 3

Well, I'm going to go ahead and spell out an imaplib solution as Cletus suggested. I don't see why people feel the need to use gmail.py or Atom for this. This kind of thing is what IMAP was designed for. Gmail.py is particularly egregious as it actually parses Gmail's HTML. That may be necessary for some things, but not to get a message count!

import imaplib, re
conn = imaplib.IMAP4_SSL("imap.gmail.com", 993)
conn.login(username, password)
unreadCount = re.search("UNSEEN (\d+)", conn.status("INBOX", "(UNSEEN)")[1][0]).group(1)

Pre-compiling the regex may improve performance slightly.

Answer 4

For a complete implementation of reading the value from the atom feed:

import urllib2
import base64
from xml.dom.minidom import parse

def gmail_unread_count(user, password):
    """
        Takes a Gmail user name and password and returns the unread
        messages count as an integer.
    """
    # Build the authentication string
    b64auth = base64.encodestring("%s:%s" % (user, password))
    auth = "Basic " + b64auth

    # Build the request
    req = urllib2.Request("https://mail.google.com/mail/feed/atom/")
    req.add_header("Authorization", auth)
    handle = urllib2.urlopen(req)

    # Build an XML dom tree of the feed
    dom = parse(handle)
    handle.close()

    # Get the "fullcount" xml object
    count_obj = dom.getElementsByTagName("fullcount")[0]
    # get its text and convert it to an integer
    return int(count_obj.firstChild.wholeText)

Answer 5

Well it isn't a code snippet but I imagine using imaplib and the Gmail IMAP instructions get you most of the way there.

Answer 6

import imaplib
obj = imaplib.IMAP4_SSL('imap.gmail.com','993')
obj.login('username','password')
obj.select()
obj.search(None,'UnSeen')
