How to make a python script to run automatically every 24 hours

Question

I have a python script test.py that sends email with an excel attachment every 24 hours. But, is there a way to make to automate this more i.e. to make this process run in the background at all times even if I close the terminal so that I don't have to start it everyday thus negating the whole purpose of automating it?

import smtplib,email,email.encoders,email.mime.text,email.mime.base
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email import encoders
from email.message import Message
from email.mime.audio import MIMEAudio
from email.mime.base import MIMEBase
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import schedule
import time

def job():
    msg = MIMEMultipart()
    # me == my email address
    # you == recipient's email address
    me = "abc@gmail.com"
    you = "xyz@gmail.com"
    password ='passwork'


    # Create message container - the correct MIME type is multipart/alternative.
    msg = MIMEMultipart('mixed')
    msg['Subject'] = "Automation Testing"
    msg['From'] = me
    msg['To'] = you

    # Create the body of the message (a plain-text and an HTML version).
    text = "Hi\n\nPlease find attached the weekly report."


    part1 = MIMEText(text, 'plain')

    #attach an excel file:
    fp = open('/Users/excelsheet.xlsm', 'rb')
    file1=email.mime.base.MIMEBase('application','vnd.ms-excel')
    file1.set_payload(fp.read())
    fp.close()
    email.encoders.encode_base64(file1)
    file1.add_header('Content-Disposition','attachment;filename=anExcelFile.xlsx')

    # Attach parts into message container.
    # According to RFC 2046, the last part of a multipart message, in this case
    # the HTML message, is best and preferred.

    msg.attach(part1)
    msg.attach(file1)

    composed = msg.as_string()

    fp = open('msgtest.txt', 'w')
    fp.write(composed)

    # Credentials (if needed)  
    # The actual mail send  
    server = smtplib.SMTP('smtp.gmail.com', 587)  
    server.starttls()  
    server.login('abc@gmail.com', password)
    server.sendmail(me, you, composed)  
    server.quit()  
    fp.close()

schedule.every().minutes.do(job)
schedule.every(24).hour.do(job)
schedule.every().day.at("10:30").do(job)

while 1:
    schedule.run_pending()
    time.sleep(1)
