This article introduces the knowledge of "how to deal with email in Python". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

I. send e-mail

The Python standard library provides smtplib to implement the SMTP protocol for sending mail. The standard library also provides email modules to help us build mail formats. SMTP (Simple Mail Transfer Protocol, simple Mail transfer Protocol) is a set of rules for sending messages from an active address to a destination address, which are used to control the way letters are transferred.

Send mail in plain text format

The code is as follows:

Import smtplibfrom email.mime.text import MIMETextfrom email.header import Header# mailbox user name sender = 'dad@qq.com' (enter your mailbox) # mailbox password (some mailboxes are authorization codes) password =' 123456'(enter your password) # recipient email address, note that [] package is required This means that you can write multiple email addresses and send receiver = ['baby@qq.com',] (enter the email address of the person you want to send) # email body text =' Hello,baby'message = MIMEText (text, 'plain',' utf-8') # sender's explicit name message ['From'] = Header (' hold the head', 'utf-8') # recipient's explicit name message [' To'] = Header ('baby') 'utf-8') # email title message [' Subject'] = 'letter from Dad Please accept!' Try: # use QQ enterprise mailbox server to send smtp = smtplib.SMTP ('smtp.qq.com') # login smtp.login (sender, password) # send smtp.sendmail (sender, receiver, message.as_string ()) print (' email sent successfully!') # exit server smtp.quit () except smtplib.SMTPException as e: print ('Error! failed to send mail!' , e)

3. Send mail in HTML format

The code is as follows:

Import smtplibfrom email.mime.text import MIMETextfrom email.header import Header# mailbox user name sender = 'dad@qq.com' (enter your mailbox) # mailbox password (some mailboxes are authorization codes) password =' 123456'(enter your password) # recipient email address, note that [] package is required This means that you can write multiple email addresses and send them in groups receiver = ['baby@qq.com',] (enter the email address of the person you want to send) # email body msg ='

Receive e-mail

There are two common protocols for accepting mail: POP3 and IMAP.

POP3 protocol (Post Office Protocol-Version3, Post Office Protocol version 3): allows the email client to download the mail on the server, but the operations on the client (such as moving mail, marking read, etc.) will not be fed back to the server, such as receiving 3 emails from the mailbox through the client and moving them to other folders, the mail on the mail server will not be moved synchronously.

IMAP protocol (Internet Mail Access Protocol, Internet mail access protocol): provides two-way communication between Webmail and the e-mail client, and any changes made on the client will be synchronized to the server. The mail is operated on the client, and the mail on the server will also be operated accordingly.

7. Download email using POP3 protocol

The code is as follows:

Import poplibfrom email.parser import Parser# login mailbox user name username = 'baby@qq.com' (enter your mailbox) # login mailbox password (some mailboxes are authorization codes) password =' 123456' (enter your password) # connect to the mailbox server pop_server = poplib.POP3 ('pop.qq.com') # print out the welcome text of the mailbox server print (pop_server.getwelcome ()) # login Mailbox server pop_server.user (username) pop_server.pass_ (password) # prints the status of the current account The first return value is the number of messages, and the second return value is print ('Server stat', pop_server.stat ()) # to get the mailing list resp, mails, octets = pop_server.list () print (mails) # to get the latest email (with the largest serial number) The message index counts from 1: index = len (mails) resp, lines, octets = pop_server.retr (index) content = b'\ r\ n'.join (lines) .decode ('utf-8') # parse the message msg = Parser (). Parsestr (content) # you can delete messages directly from the server # pop_server.dele (index) # close the connection pop_server.quit ()
