PYTHON: SMTP Email with HTML and Multiple Attachments

send_email2.py

# Found most ofthis at http://ryrobes.com/python/python-snippet-sending-html-email-with-an-attachment-via-google-apps-smtp-or-gmail/
# Adapted to accept a list of files for multiple file attachments
# From other stuff I googled, a little more elegant way of converting html to plain text
# This works in 2.7 and my brain gets it.

Thank you for sharing!

In this Part : **if 'attachments' in globals() and len('attachments') > 0: # are there attachments?**

condition len('attachments') > 0 will always true , you should write it as len(attachments) > 0 (wihtout the quote characters) then it will check wether the attachment list contain something or empty

note: I am using python 3.4 right now

Looks great! How would I send a whole folder?

Make a list of files in the directory and iterate over the list.

Thanks for the code!! Is there a way to send mails to multiple receivers?
