Python发送邮件需要smtplib和email两个模块。也正是由于我们在实际工作中可以导入这些模块，才使得处理工作中的任务变得更加的简单。今天，就来好好学习一下使用Python发送邮件吧。
SMTP是发送邮件的协议，Python内置对SMTP的支持，可以发送纯文本邮件、HTML邮件以及带附件的邮件。
Python对SMTP支持有smtplib和email两个模块，email负责构造邮件，smtplib负责发送邮件。

content = '...'
if send_mail(mailto_list, sub, content):
print "发送成功"
else:
print "发送失败"

2.邮件正文是表格的格式：由于是表格，所以我们选择HTML来实现表格的功能，邮件上面显示的就是HTML实现的内容了。

sub = "天才白痴梦"
html = '<html></html>'
if send_mail(mailto_list, sub, html):
print "发送成功"
else:
print "发送失败"

3.邮件正文是图片的格式：要把图片嵌入到邮件正文中，我们只需按照发送附件的方式，先把邮件作为附件添加进去，然后，在HTML中通过引用src="cid:0"就可以把附件作为图片嵌入了。如果有多个图片，给它们依次编号，然后引用不同的cid:x即可。
