Running an external Python script on a Django site
Since you don't want code, and you didn't get detailed on everything required required, here's my suggestion:

Make sure your admin.py file has editable fields for the model you're using.
Make an admin action,
Take the selected row with the values you entered, and run that action with the data you entered.

I would be more descriptive, but I'd need more details to do so.
I have a Python script which communicates with a Financial site through an API. I also have a Django site, i would like to create a basic form on my site where i input something and, according to that input, my Python script should perform some operations. 
How can i do this? I'm not asking for any code, i just would like to understand how to accomplish this. How can i "run" a python script on a Django project? Should i make my Django project communicate with the script through a post request? Or is there a simpler way?
