Python Adventures

Problem
You want to send an email to yourself from a script.

Solution
You can find here how to do it from a Bash script. That solution uses the mailx command.

Here is a simple Python wrapper for the mailx command:

#!/usr/bin/env python3
# coding: utf8

import os

DEBUG = True
# DEBUG = False

class NoSubjectError(Exception):
    pass

class NoRecipientError(Exception):
    pass

def send_email(to='', subject='', body=''):
    if not subject:
        raise NoSubjectError
    if not to:
        raise NoRecipientError
    #
    if not body:
        cmd = """mailx -s "{s}" < /dev/null "{to}" 2>/dev/null""".format(
            s=subject, to=to
        )
    else:
        cmd = """echo "{b}" | mailx -s "{s}" "{to}" 2>/dev/null""".format(
            b=body, s=subject, to=to
        )
    if DEBUG:
        print("#", cmd)
    #
    os.system(cmd)

def main():
    send_email(to="[email protected]",
               subject="subject")
    #
    send_email(to="[email protected]",
               subject="subject",
               body='this is the body of the email')
