Email Results of Function

[anelliaf]

That was it, thx! Adding "return" makes total sense. With "print", it was outputting to stdout before the script sent the email.

Here's the final code:

from email.headerregistry import Address
from email.message import EmailMessage
from email.mime.text import MIMEText
import os
import smtplib
import psutil

# mail server details
mail_server = 'localhost'
mail_server_port = 25

# email addresses
email_address = ''
recipient_address = ''
subject_desc = 'Test'

# linux mount points
def mounts():
    results = []
    devs = psutil.disk_partitions()
    for dev in devs:
            part = int(psutil.disk_usage(dev.mountpoint).percent)
            if part > 40:
                    results.append([dev.mountpoint, part])
    return results

list_mounts = list(mounts())

def list_out(list_in):
    return '\n'.join('Drive: {0:10s} Used Space: {1:5.2f}'.format(*drive) for drive in list_in)

email_body = list_out(list_mounts)

# email function
def create_email_message(from_address, to_address, subject, body):
        msg = EmailMessage()
        msg['From'] = from_address
        msg['To'] = to_address
        msg['Subject'] = subject
        msg.set_content(body)
        return msg

if __name__ == '__main__':
        msg = create_email_message(
                from_address=email_address,
                to_address=recipient_address,
                subject=subject_desc,
                body=email_body
        )


with smtplib.SMTP(mail_server, mail_server_port) as smtp_server:
        smtp_server.ehlo()
        smtp_server.send_message(msg)

print('Email sent successfully')

Thanks everyone for your help with this!
