You have a python script to do this, right?

You don't need a file object. Build the thing you want to send as a 
string called data, and have a string variable called filename 
containing the name you want to use for the attachment.

Then you need create a MIMEBase object for it:

# some imports
from email.MIMEBase import MIMEBase
from email import Encoders

# now create the attachment
msg = MIMEBase(maintype, subtype)
msg.set_payload(data)
Encoders.encode_base64(msg)
msg.add_header('Content-Disposition', 'attachment',
                filename=filename)

# now render the MailTemplate
wrapper = context.my_mail_template.as_message(
     # insert params here
     )
# finally, attach the file and send
wrapper.attach(msg)
wrapper.send()
