1. smtplib
This webpage has a very clear and basic code snippet for sending an email:
https://www.tutorialspoint.com/python/python_sending_email.htm

With this package, you have to provide the server details as in this line of code:
smtpObj = smtplib.SMTP('localhost')

Or as in here:
# creates SMTP session 
s = smtplib.SMTP('smtp.gmail.com', 587) # 587 is port.

Or
server = smtplib.SMTP('smtp.gmail.com:587')

An Example

def send_email_gmail(subject, message, destination):
    # First assemble the message
    msg = MIMEText(message, 'plain')
    msg['Subject'] = subject

    # Login and send the message
    port = 587
    my_mail = 'my_mail@hotmail.com'
    my_password = 'my_password'
    with smtplib.SMTP('smtp-mail.outlook.com', port) as server:
        server.starttls()
        server.login(my_mail, my_password)
        server.sendmail(my_mail, destination, msg.as_string())

SENDING MAIL VIA SSL

import smtplib, ssl
from email.mime.text import MIMEText

def send_email(subject, message, destination):
    # First assemble the message
    msg = MIMEText(message, 'plain')
    msg['Subject'] = subject

    # Login and send the message
    port = 465
    my_mail = 'me@gmail.com'
    my_password = 'me'
    context = ssl.create_default_context() 
    with smtplib.SMTP_SSL('smtp.gmail.com', port, context=context) as server:
        server.login(my_mail, my_password)
        server.sendmail(my_mail, destination, msg.as_string())

send_email('Test subject', 'This is the message', 'to_email@email.com')
