How to pass parameter variable from Django web to python script?

Question

I have a python script that will be triggered to read an inbox and send email to an gmail account when some condition is meet. In order to send , the script will filter through subject or text of the incoming email. Currently the script is just hard-coded format and I prefer the condition is dynamically set by the user. I created a django website and let user to input their condition, but I do not know how can I pass the parameter from the web to my python script. I already do my researched on the internet but couldn't found any useful source, does anyone can help me or send my any related article for me to read ? Thanks

My py script

import datetime
import email
import imaplib
import mailbox
import smtplib

EMAIL_ACCOUNT = "[email protected]"
PASSWORD = "xxx"

mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login(EMAIL_ACCOUNT, PASSWORD)
mail.list()
mail.select('inbox')
result, data = mail.uid('search', None, "UNSEEN") # (ALL/UNSEEN)
i = len(data[0].split())

for x in range(i):
    latest_email_uid = data[0].split()[x]
    result, email_data = mail.uid('fetch', latest_email_uid, '(RFC822)')
    # result, email_data = conn.store(num,'-FLAGS','\\Seen')
    # this might work to set flag to seen, if it doesn't already
    raw_email = email_data[0][1]
    raw_email_string = raw_email.decode('utf-8')
    email_message = email.message_from_string(raw_email_string)

    # Header Details
    date_tuple = email.utils.parsedate_tz(email_message['Date'])
    if date_tuple:
        local_date = datetime.datetime.fromtimestamp(email.utils.mktime_tz(date_tuple))
        local_message_date = "%s" %(str(local_date.strftime("%a, %d %b %Y %H:%M:%S")))
    email_from = str(email.header.make_header(email.header.decode_header(email_message['From'])))
    email_to = str(email.header.make_header(email.header.decode_header(email_message['To'])))
    subject = str(email.header.make_header(email.header.decode_header(email_message['Subject'])))

    # Body details
    for part in email_message.walk():

        if part.get_content_type() == "text/plain":
            body = part.get_payload(decode=True)
            print("From:", email_from)

            print("Email To:", email_to)
            print("date:", local_message_date)
            print("Subject:", subject)
            print("body:", body.decode('utf-8'))

            '''If subject have test it will send specific email to recipient'''
            if "Consent"  in subject:
                server = smtplib.SMTP('smtp.gmail.com', 587)
                server.starttls()
                server.login(EMAIL_ACCOUNT, PASSWORD)

                msg = "ALERT NOTICE!"
                server.sendmail(EMAIL_ACCOUNT, "[email protected]", msg)
                server.quit()
            else:
                print( "no email");

        else:
            continue

If your condition data is serializable, then you can use Celery to run python script. It'll be as simple as:

# in your Django code that run on user submitting data
...
send_email.delay()
...

# Celery task
@shared_task(bind=True)
def send_email(list_of_your_condition_parameters):
    # do job
