How to send output from a python script to an email address

问题

I have a threaded python script that pings 20 nodes on a local area network, and prints out the status of each: Node is Alive, Node is Down, etc.. I would like to have this output sent to my email account, Because I intend to make this script to run once a week, on it's own, And if i'm physically away from the lan I won't have to worry, I can just check my email.

Language:PYTHON. OS:Linux Mint 10 Julia. Thanks

If it runs once a week, you will probably run it from crontab?

Use smtplib. The example they provide is pretty good.

import smtplib

def prompt(prompt):
    return raw_input(prompt).strip()

fromaddr = prompt("From: ")
toaddrs  = prompt("To: ").split()
print "Enter message, end with ^D (Unix) or ^Z (Windows):"

# Add the From: and To: headers at the start!
msg = ("From: %s\r\nTo: %s\r\n\r\n"
       % (fromaddr, ", ".join(toaddrs)))
while 1:
    try:
        line = raw_input()
    except EOFError:
        break
    if not line:
        break
    msg = msg + line

print "Message length is " + repr(len(msg))

server = smtplib.SMTP('localhost')
server.set_debuglevel(1)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()

Take a look at the logging and logging.config, I've used this before to receive error messages from a script running in the background

http://docs.python.org/library/logging.html

For example

import logging
import logging.config

logDir = "./logs/"

logging.config.fileConfig(logDir+'logging.conf')
logger = logging.getLogger('email')

logger.debug('THIS IS A DEBUG MESSAGE')
logger.error('THIS IS AN ERROR')

And then the logging.conf

[loggers]
keys=root,email

[logger_root]
level=DEBUG
handlers=rotatingFileHandler

[logger_email]
level=ERROR
handlers=email
qualname=email

[formatters]
keys=emailFormatter,rotatingFormatter

[formatter_emailFormatter]
format=%(asctime)s %(name)-12s %(levelname)-8s %(message)s

[formatter_rotatingFormatter]
format=%(asctime)s %(name)-12s %(levelname)-8s %(message)s
datefmt=%m-%d %H:%M

[handlers]
keys=email,rotatingFileHandler

[handler_email]
class=handlers.SMTPHandler
level=ERROR
formatter=emailFormatter
args=('mail.xxx','x@x.com',['y@y.com',],'ERROR!',('x@x.com','xxx'))

[handler_rotatingFileHandler]
class=handlers.RotatingFileHandler
level=DEBUG
formatter=rotatingFormatter
args=('./logs/log.out', 'maxBytes=1000000', 'backupCount=5')

From the above I would receive "THIS IS AN ERROR" in my email.

Instead of having your main print the output, you could use a logger

You can set up a logger as follows:

import logging
log_file = r'C:\Users\user\Downloads\LogFileName.log'

logging.basicConfig(
    filename=log_file,
    filemode='w',
    format='[%(asctime)s] %(levelname)-6s %(message)s',
    datefmt='%Y-%m-%d %H:%M:%S')

logger = logging.getLogger()
logger.setLevel(logging.INFO)

Now in your script replace every print statement with logger.info

Example before:

print("Printing status")

Example after:

logger.info("Printing status")

Then you can email the log to yourself as follows:

import smtplib
from email.message import EmailMessage
import os
msg_body = "Body Text"

msg = EmailMessage()

msg['Subject'] = "Subject"
msg['From'] = "send_from@email.com"
msg['To'] = "send_to@email.com"

msg.set_content(msg_body)

if os.path.isfile(log_file):
        msg.add_attachment(open(log_file, "r").read(), filename=os.path.basename(log_file))


# Send the message via our own SMTP server.
s = smtplib.SMTP("smtpa.server")
s.send_message(msg)
s.quit()

You need a SMTP server to send Email. Check out the smtplib for Python
