Q:

Python search imap email for a string

New to python, having some trouble getting past this.
Am getting back emails from gmail via imap (with starter code from https://yuji.wordpress.com/2011/06/22/python-imaplib-imap-example-with-gmail/) and want to search a specific email (which I am able to fetch) for a specific string. Something like this
ids = data[0]
id_list = ids.split()
ids = data[0]
id_list = ids.split()
latest_email_id = id_list[-1]
result, data = mail.fetch(latest_email_id, "(RFC822)") 
raw_email = data[0][1] 

def search_raw():
    if 'gave' in raw_email:
        done = 'yes'
    else:
        done = 'no'

and it always sets done to no. Here's the output for the email (for the body section of the email)
Content-Type multipart/related;boundary=1_56D8EAE1_29AD7EA0;type="text/html"
--1_56D8EAE1_29AD7EA0
Content-Type text/html;charset="UTF-8"
Content-Transfer-Encoding base64

I know the issue is the html, but can't seem to figure out how to parse the email properly. 
Thank you!

A:

The text above is base64 encoding. Python has a module named base64 which gives you the ability to decode it.
import base64
import re

def has_gave(raw_email):
    email_body = base64.b64decode(raw_email)
    match = re.search(r'.*gave.*', email_body , re.IGNORECASE)
    if match:
        done = 'yes'
        print 'match found for word ', match.group()
    else:
        done = 'no'
        print 'no match found'

    return done
