Python 3.4发送给多个接收者的电子邮件会抛出一个ERROR

Question

我正在编写一个脚本，向多个电子邮件帐户发送电子邮件，但还不能。

它的工作原理如下，但如果我设置receivers='[e-mail]','[e-mail]'，它就不会工作，它会抛出一个错误：

AttributeError: 'tuple' object has no attribute 'encode'. 

如何设置receivers=？

def send_email (out_file):
    sender = '[e-mail]'
    receivers = '[e-mail]'
    email_pass = 'aaaa'
    filematch=re.findall('NE.*.txt',out_file.name)
    subject = ("NEXXXX_price_update")
    message = ("The following file was forwarded to your ftp account %s "  %filematch)
    msg = 'Subject: %sn%s' %(subject, message)

    try:
        smtpObj = smtplib.SMTP_SSL('smtp.gmail.com',0)
        smtpObj.login(receivers, email_pass)
        smtpObj.sendmail(sender, receivers, msg)
        print ("Successfully sent email")
    except SMTPException:        
        print ("email NOT successful")
        print(SMTPException.__cause__)        
        smtpObj.quit() 

Answer 1

您分配错误的

receivers='[e-mail]','[e-mail]'

您假设分配为tuple或list，但不能100%确定是哪个。

试试看：

receivers=('[e-mail]','[e-mail]')

或

receivers=['[e-mail]','[e-mail]']
