Python：不断检查新电子邮件并提醒更多新电子邮件

Question

我有这段代码可以检查最新的电子邮件，然后去做一些事情。是否可以写一些东西来不断检查收件箱文件夹是否有新邮件？虽然我希望它继续检查最新的新电子邮件。如果我尝试存储它已经通过一次，它会变得太复杂吗？因此，它不会针对同一封电子邮件提醒同一封电子邮件两次。

代码：

import imaplib
import email
import Tkinter as tk

word = ["href=", "href", "<a href="] #list of strings to search for in email body

#connection to the email server
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login('xxxx', 'xxxx')
mail.list()
# Out: list of "folders" aka labels in gmail.
mail.select("Inbox", readonly=True) # connect to inbox.

result, data = mail.uid('search', None, "ALL") # search and return uids instead

ids = data[0] # data is a list.
id_list = ids.split() # ids is a space separated string
latest_email_uid = data[0].split()[-1]

result, data = mail.uid('fetch', latest_email_uid, '(RFC822)') # fetch the email headers and body (RFC822) for the given ID


raw_email = data[0][1] # here's the body, which is raw headers and html and body of the whole email
# including headers and alternate payloads

.....goes and does other code regarding to email html....

尝试使用这种方法：

逻辑与@tripleee 评论中的逻辑相同。

import time
word = ["href=", "href", "<a href="] #list of strings to search for in email body

#connection to the email server
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login('xxxx', 'xxxx')
mail.list()
# Out: list of "folders" aka labels in gmail.
latest_email_uid = ''

while True:
    mail.select("Inbox", readonly=True)
    result, data = mail.uid('search', None, "ALL") # search and return uids instead
    ids = data[0] # data is a list.
    id_list = ids.split() # ids is a space separated string

    if data[0].split()[-1] == latest_email_uid:
         time.sleep(120) # put your value here, be sure that this value is sufficient ( see @tripleee comment below)
    else:
         result, data = mail.uid('fetch', latest_email_uid, '(RFC822)') # fetch the email headers and body (RFC822) for the given ID
         raw_email = data[0][1]
         latest_email_uid == data[0].split()[-1]
         time.sleep(120) # put your value here, be sure that this value is sufficient ( see @tripleee comment below)
