Organizing justpy project folder structure and importing modules and invoking functions in jp

[munna123321]

I wanted to do ML project. Justpy happens to be good but how to organize the files into standard web application project and import modules and functions into jp?
if the code is very large how to organize justpy code into standard web application folder structure type Django/flask?
Like frontend/subfolders, templates, assets server/subfolders , authentication etc..
I did not come across importing modules into jp. How to import modules into jp?
Or can I add packages and call functions from jp?

A Justpy project does not require any special structure.
What I do is the following: I have the main file in which the import justpy and jp.justpy commands are as well as the request handlers and event handlers. Then I have some utility and specific function files from which I import to the main file as required.

I want to develop ML based multipage web application.
Maintaining in a single file looks very disorganized. Need not be as large as Django type folder structure.
But should have small number of files along with assets and static files with delineation between server and frontend code.

Can you give small piece of code small function file import into the main file and invoking the function.
Thanks

I may be misunderstanding what the issue is

I am thinking following lines
main.py {
import just.py as jp
//do i have to import page1.py as pg1 & page2.py as pg2?? in main.py
. //declare menu items for page1 & page2
//on_click navigates to page1 & page2
}
page1.py {
//display default data from database processed in server1.py
//do i have to import server1 as ser1
//user selects some data in page1. server1 receives data from page1 and passes data to page1 text box
}
page2.py {
//user selects video data
//server2.py gets from database or issues api request and passes data to page2 video player
}

/user selects some data in page1. server1 receives data from page1 and processes using some algorithm and passes data to page1 text box

Another problem is
server2.py may have jp.html_string object formatted to display page2 html
server1.py also has jp.html_string to display page1 html.
Since jp is a global module , how is that html_string is selected?
Is it i have to declare local/global variables of type html_string objects and assign to jp.html_string object at the of navigating?

How about the following structure for main.py:

import justpy as jp

from server1 import first_page_creation_function  # function returns WebPage instance
from server2 import second_page_creation_function

class GlobalData:

    data: {}

# Set the global data to what you need

@jp.SetRoute('/firstpage')
def serve_first_page(request):
    return first_page_creation_function(request, GlobalData, jp)

@jp.SetRoute('/secondpage')
def serve_second_page(request):
    return second_page_creation_function(request, GlobalData, jp)

jp.justpy()
