Python을 사용하여 이메일에 파일을 쉽게 첨부하려면 어떻게 해야 합니까?

import smtplib
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

# Define email details
sender = 'alice@example.com'
recipients = ['bob@example.org', 'carol@example.net']
subject = 'Hello from Python!'
text_body = 'This is the email body.'
files = ['file1.txt', 'file2.pdf']

# Create the email message
message = MIMEMultipart()
message['From'] = sender
message['To'] = ', '.join(recipients)
message['Subject'] = subject
message.attach(MIMEText(text_body))

# Attach files
for filename in files:
    with open(filename, 'rb') as f:
        attachment = MIMEApplication(f.read(), Name=filename)
    attachment['Content-Disposition'] = 'attachment; filename="%s"' % filename
    message.attach(attachment)

# Send the email
smtp = smtplib.SMTP('localhost')
smtp.sendmail(sender, recipients, message.as_string())
smtp.quit()
