Sending emails from Python

To make it more easy and coherent to send emails from Python, we have created a small wrapper around the standard Python smtplib module. This wrapper is called SendEmail and is located can be imported into your Python script by using the following code:

from pyprediktorutilities.send_email import SendEmail

You’ll need an SMTP server to send emails. If you don’t have a specified server in your project (e.g. from the client), you can use the generic outbound server you’ll find by searching for “SMTP” in Keeper Security.

Note

If you don’t have a specified server in your project (e.g. from the client), you can use the generic outbound server you’ll find by searching for “SMTP” in Keeper Security. The SMTP server requires authentication. The username and password can be found in the Keeper Security.

You’ll instantiate the SendEmail class by using the following code:

email = SendEmail(smtp_server, smtp_port, smtp_username, smtp_password)

The only function in the SendEmail class is the send_email() function. This function takes the following arguments:

• from_email - The email address of the sender

• recipients - A list of email addresses of the recipients

• subject - The subject of the email

• body - The message of the email

• files - A list of file paths to the attachments

The function raises an exception if the email could not be sent and will log the results if you have defined a logger in your script.

Putting it all together, you’ll have the following code:

from pyprediktorutilities.send_email import SendEmail

email = SendEmail(smtp_server, smtp_port, smtp_username, smtp_password)
email.send_email(
    "no-reply@nowhere.com",
    ["someone@somewhere.com"],
    subject, body, files)

Note

If you combine this with the template engine, you can send emails with HTML content.
