I am using python 3.5 and below code is mostly from the google api page... https://developers.google.com/gmail/api/guides/sending slightly revised for python 3.x

i could successfully send out the email with the content text and an attachment pdf but the pdf attached is completely blank..

please help and thanks in advance

def create_message_with_attachment(bcc, subject, message_text,  file,sender='me' ):message = MIMEMultipart()message['bcc'] = bccmessage['from'] = sendermessage['subject'] = subjectmsg = MIMEText(message_text)message.attach(msg)content_type, encoding = mimetypes.guess_type(file)main_type, sub_type = content_type.split('/', 1)fp = open(file, 'rb')msg = MIMEBase(main_type, sub_type)msg.set_payload(fp.read())fp.close()filename = os.path.basename(file)msg.add_header('Content-Disposition', 'attachment', filename=filename)message.attach(msg)raw = base64.urlsafe_b64encode(message.as_bytes())raw = raw.decode()return {'raw':raw}

you just forgot to encode the attachment. Replace two lines of your code with those:

  import email.encoders...msg.add_header('Content-Disposition', 'attachment',filename=filename)email.encoders.encode_base64(msg)message.attach(msg)...
