發送給多個接收者的Python 3.4電子郵件引發錯誤

Question

我正在編寫一個腳本，以將電子郵件發送到多個電子郵件帳戶，但還不能。

它按下面的方式工作，但是如果我將receivers='xxx@xxx.com','yyy@yyy.com'為無效，則會引發錯誤：

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

如何設置receivers= ？

def send_email (out_file):

    sender = 'xxx@xxx.com'
    receivers = 'xxx@xxx.com'
    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: %s\n%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

您分配錯誤

receivers='xxx@xxx.com','yyy@yyy.com'

您假設將其分配為tuple或list ，但不確定100％是哪一個。

試一下：

receivers=('xxx@xxx.com','yyy@yyy.com')

要么

receivers=['xxx@xxx.com','yyy@yyy.com']
