Python 3.3中的電子郵件附件問題

Question

我試圖通過Python 3.3的電子郵件附件發送PDF。我搜索瞭如何做到這一點，發現另外一個問題這個代碼在這個網站：

import smtplib, os 
from email.mime.multipart import MIMEMultipart 
from email.mime.base import MIMEBase 
from email.mime.text import MIMEText 
from email.utils import COMMASPACE, formatdate 
from email import encoders 

def send_mail(send_from, send_to, subject, text, files=[], server="localhost", port=587, username='', password='', isTls=True): 
    msg = MIMEMultipart() 
    msg['From'] = send_from 
    msg['To'] = COMMASPACE.join(send_to) 
    msg['Date'] = formatdate(localtime = True) 
    msg['Subject'] = subject 

    msg.attach(MIMEText(text)) 

    for f in files: 
     part = MIMEBase('application', "octet-stream") 
     part.set_payload(open(f,"rb").read()) 
     encoders.encode_base64(part) 
     part.add_header('Content-Disposition', 'attachment; filename="{0}"'.format(os.path.basename(f))) 
     msg.attach(part) 

    smtp = smtplib.SMTP(server, port) 
    if isTls: smtp.starttls() 
    smtp.login(username,password) 
    smtp.sendmail(send_from, send_to, msg.as_string()) 
    smtp.quit() 

我叫我輸入的函數，並且得到一條錯誤：

File "C:\Python33\mailAttach.py", line 46, in send_mail 
    msg.attach(MIMEText(text)) 
File "C:\Python33\lib\email\mime\text.py", line 34, in __init__ 
    _text.encode('us-ascii') 
AttributeError: 'list' object has no attribute 'encode' 

有誰知道解？提前致謝。

這不能說是肯定的，但可能問題在於你提到的那些投入並且不報告。
例如，下面的代碼沒有給出問題：

Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:06:53) on Windows (64 bits). 
This is the IEP interpreter. 
Type "help" for help, type "?" for a list of *magic* commands. 
>>> from email.mime.multipart import MIMEMultipart as MM 
>>> from email.mime.text import MIMEText as MT 
>>> msg = MM() 
>>> msg.attach(MT('hello')) 

但是，如果你發送的text參數作爲一個列表，然後你會得到完全回溯你彙報：

>>> msg.attach(MT(['hello'])) 
Traceback (most recent call last): 
    File "<console>", line 1, in <module> 
    File "c:\python33\lib\email\mime\text.py", line 34, in __init__ 
    _text.encode('us-ascii') 
AttributeError: 'list' object has no attribute 'encode'
