How to send a text message with python

pythonsms.py

# sms.py
# Sends sms message to any cell phone using gmail smtp gateway
# Written by Alex Le

import smtplib

# Use sms gateway provided by mobile carrier:
# at&t:     [email protected]
# t-mobile: [email protected]
# verizon:  [email protected]
# sprint:   [email protected]

# Establish a secure session with gmail's outgoing SMTP server using your gmail account
server = smtplib.SMTP( "smtp.gmail.com", 587 )

server.starttls()

server.login( '<gmail_address>', '<gmail_password>' )

# Send text message through SMS gateway of destination number
server.sendmail( '<from>', '<number>@tmomail.net', '<msg>' )

I used this method and It worked great! Is there any way though that I can get the script to respond to a message in the conversation?

For those interested, here is an implementation with multiple carriers + and async support: https://bit.ly/send-txt-msg

Do you guys know how to remove the subject when you send the text? Like the forward slashes? I just get / no subject / when I leave it blank
