EmailAttachment.py

'''
Python email Sender, with attachments

This code can automatically send emails from your address to any given address.
It can also attach files to the email.

The primary purpose of this script is to send an email to a friend with an
attached music file. Using .bat files and task scheduler, a daily email can be
sent to your friend without any intervention required on your part.
You will need to replace my email and the dummied out password for your email
and password for the code to work.
Currently only works out of the box for gmail addresses.
[Your computer does need to be on and connected to the internet for this to work]
[But this code could easily run on an always on raspberry pi, or an Amazon
server if need be]
