#50 - linked main.py with Session_dashboard.py

[Deepak-Kumbhar2006]

Working on #50
Session.py will run from main.py
yet need to work on session_analysis.py, just making 1 step forward in #50.
In future many functions are going to be included in analysis file.
for now its just a blank tkinter GUI for other candidate to work on that.

1. Entry Point Guard

Right now, the Tk window is created on import. Please wrap the launch in a main() function and add an import guard:

def main():
root = tk.Tk()
root.geometry(WINDOW_SIZE)
root.title(APP_TITLE)

notebook = ttk.Notebook(root)
live_track = ttk.Frame(notebook)
session_his = ttk.Frame(notebook)

notebook.add(live_track, text="Live Tracking")
notebook.add(session_his, text="Session History")
notebook.pack(expand=True, fill="both")

root.mainloop()

if name == "main":
main()

2. Avoid Wildcard Imports

Instead of:

from tkinter.ttk import *

Use explicit imports:

import tkinter as tk
from tkinter import ttk

3. Structure for Future Work

Since more functionality will be added in #50, consider using a class or at least helper methods for each tab. Example:

def build_live_tracking_tab(parent):
frame = ttk.Frame(parent, padding=10)
ttk.Label(frame, text="Live Tracking — TODO").pack(anchor="w")
return frame

4. Widget Packing

Use expand=True, fill="both" when packing the notebook so it resizes properly:

notebook.pack(expand=True, fill="both")

5. Code Style / Maintainability

Add constants instead of hardcoding values:

WINDOW_SIZE = "600x400"
APP_TITLE = "Session Analysis"

Also add small docstrings or # TODO comments inside tabs so contributors know where to extend.

✅ With these changes, the app will be safer to import, resize correctly, and easier for contributors to extend.
