python – HTML代码中不必要的感叹号(！)

from email.mime.text import MIMEText
from smtplib import SMTP

def email (body,subject):
    msg = MIMEText("%s" % body, 'html')
    msg['Content-Type'] = "text/html; charset=UTF8"
    msg['Subject'] = subject
    s = SMTP('localhost',25)
    s.sendmail('[email protected]', ['[email protected]'],msg=msg.as_string())

def main ():
    # open gerrit.txt and read the content into body
    with open('gerrit.txt', 'r') as f:
        body = f.read()
    subject = "test email"
    email(body,subject)
    print "Done"

if __name__ == '__main__':
    main()

Note that mailservers have a 990-character limit on each line
contained within an email message. If an email message is sent that
contains lines longer than 990-characters, those lines will be
subdivided by additional line ending characters, which can cause
corruption in the email message, particularly for HTML content. To
prevent this from occurring, add your own line-ending characters at
appropriate locations within the email message to ensure that no lines
are longer than 990 characters.

我认为你必须将你的HTML分成几行.您可以使用textwrap.wrap方法.
