How would you scan an email for a key, perform a task once that key is found, and then completely exit the code once that task has been finished?

Question

Basically I am just trying to figure out a way to run certain processes while I am out of the office. I want to just set up a quick template code by performing a fairly simple process (like restarting my printer). The issue that I am having at the moment is that when I run this code I can't figure out a good way to kill the code entirely after the process has executed.

The code that I am using:

import imaplib
import time
import sys

user = '#my email'
password = '#my password'

server = 'imap.gmail.com'
mailbox = 'Inbox'
    




while True:

    try:
        imap = imaplib.IMAP4_SSL(server)
        imap.login(user, password)
        
        email_count = imap.select(mailbox, True)
        results, data = imap.search(None, '(FROM "#my email" SUBJECT "Test")')
        
        ids = data[0]
        id_list = ids.split()
        latest_email_id = id_list[-1]
        result, data = imap.fetch(latest_email_id, "(RFC822)")
        raw_email = data[0][1]
        print(raw_email)
       
        imap.logout


    except:
        print("no email found")

    
    
    time.sleep(60)
