#77420 — error while writing program to send mail.

Hi,

I am writing this program from 
https://docs.python.org/2/library/email-examples.html

but getting the error as

singhom@debian:~/pythons$ python send_email.py
Traceback (most recent call last):
   File "send_email.py", line 18, in <module>
     msg['Subject']  = 'The contents of $s' % message
NameError: name 'message' is not defined


i know the error would be something simple and i am overlooking it, any 
help would be highly appreciated, I am sorry, but I am very new to 
python programming.

code starts here.
#/usr/bin/python2.7 -tt

## sending a simple text message using python.
import smtplib

from email.mime.text import MIMEText

# Open file for reading.
fp = open("message", 'rb')
# Create a plain text message.
msg = MIMEText(fp.read())

fp.close

me = "torque.india@gmail.com"
you = "oomprakash@gmail.com"

msg['Subject']  = 'The contents of $s' % message
msg['From'] = me
msg['To'] = you

# Send message thorugh localhost but don't include the envelope headers.

s = smtplib.SMTP('localhost')
s.sendmail(me, [you], msg.as_string())
s.quit()

"message" here is a string literal

> fp.close

should be fp.close()

> msg['Subject']  = 'The contents of $s' % message

message here is a variable. The variable named message has not previously 
had a value assigned to it.
$s should be %s

If you want the subject to be the filename, then what you need to do is:

1) assign the filename to some variable
2) open the file using the variable that contains the filename
3) use the variable that contains the filename to generate the subject

eg (assuming suitable imports etc) and the message is in a text file 
called message.txt:
 
msgfile = "message.txt"
fp = open( msgfile, "r" )
msg = MIMEText(fp.read())
fp.close()
msg['Subject']  = 'The contents of %s' % msgfile
