Email script to check mounted volumes at certain time

I'm looking for either bash or python script to check mounted volumes at the end of the day. I found a python email script,  just need the volume check added into the script.

Thanks!

# Now send the message
mailer = smtplib.SMTP(SMTP_SERVER, SMTP_PORT)
mailer.sendmail(SMTP_FROM, [SMTP_TO], msg.as_string())
mailer.close()
