Example code for sending emails in python (html, images, and attachments are supported)

Some examples of sending emails using python are as follows:

The code is as follows:

#! /Usr/bin/python
#-*-Coding: UTF-8 -*-

Import email
Import mimetypes
From email. MIMEMultipart import MIMEMultipart
From email. MIMEText import MIMEText
From email. MIMEImage import MIMEImage
Import smtplib

Def sendEmail (authInfo, fromAdd, toAdd, subject, plainText, htmlText ):

If not (server and user and passwd ):

Return

# Encapsulate the plain and HTML versions of the message body in
# 'Alternative 'part, so message agents can decide which they want to display.

Password = '***'

Msg = MIMEText (' ', 'text', 'utf-8') # The parameter 'utf-8' is required for Chinese characters and is not required for single-byte characters.
Msg ['subobject'] = Header (Subject, 'utf-8 ')

Part1 = MIMEText (text, 'plain ')
Part2 = MIMEText (html, 'html ')

# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# The HTML message, is best and preferred.
