Python method of using e-mail module smtplib (send picture attachment) practical and feasible

SMPTP class definition: Smtplib. SMTP (Host[,port[,local_hostname[,,timeout]]), as the constructor of SMTP, the function is to establish a connection with the SMTP server, after the successful connection, you can send related requests to the server, such as login, check, send, exit and so on. The host parameter is a remote SMTP host address, such as stmp.163.com;port for a connection port, and the default is 25;local_hostname to send Helo/ehlo instructions on the local FQDN (full domain name). Timeout is a connection or attempt to time out in most seconds, the SMTP class has the following methods:
Smtp.connect ([Host[,port]) method, connect the remote SMTP host method, host is the remote host address, Port is the remote host SMTP port, default 25, can also be directly used in the form of Host:port, for example: Smtp.connect ("smtp.163.com", "25").
Smtp.login (User,password) method, the remote SMTP host check method, parameters for the user name and password, such as Smtp.login ("[Email protected]", ' 123456 ').
Smtp.sendmail (From_addr,to_addrs,msg[,mail_options,rcpt_options]) method, to implement the message sending function, the parameters are the sender, the recipient, the message content, for example: Smtp.sendmail ("[Email protected]", ' [email protected] ', body), where the body content is defined as follows:
"" "From:[email protected]
To:[email protected]
Subject:test Mail
Test mail Body "" "
SMTP.STARTTLS ([Keyfile[,certfile]) method, enable TLS (secure transport) mode, all SMTP instructions are encrypted, such as the use of Gmail's STMP server need to start this to send mail normally
Smtp.quit () method, connection to the Port SMTP server

Implementing HTML-formatted data report messages
Plain text mail content has not been able to meet our diverse needs, this example through the introduction of the Email.mime Mimetex class to implement HTML-enabled messages, support all HTML elements, including tables, images, animations, CSS styles, forms and so on. This example uses HTML tables to customize the perfect business Traffic report with the following code:

Example 2: Implementing a graphics-formatted server performance report message
When a message content containing picture data needs to be referenced, a reference to the Mimeimage class is required, and if the message body consists of multiple MIME objects, it is also necessary to reference the Mimemultipart class for encapsulation. This example uses the combination of the Mimetext and Mimeimage classes to customize the server performance report messages in the graphics format, with the following code implementation:
