Hello,
I have two python scripts. First is quickstart.py ans second is dater.py. My goal is to run first script and then inside call second script. I tried with sub-process but without success. The main problem is that window from tkinter runs twice. What does it mean? I am setting Start date and End date in calendar, then clicking Apply and at the end clicking X for closing windows. Right after close I am getting another same window which I need to close to go further with script. How to handle that?

dater.py creates a window when it is imported in your script. A second dater.py is created when you run(["python", "dater.py"]).

I would import dater.py and create an instance from the script instead of running it as a subprocess. Creating the window from your script will make it easier to get the selected dates than trying to get the subprocess to return information.

Either way you need to modify dater to behave like a dialog. Currently dater is a window. There is no way for your dater window to return date information to your script. When the dater window is visible, the window blocks your script from running. That's fine, because you want your script to wait until it has the date information. But when the window is closed, all the date information gets deleted along with the window. By the time your script knows the window is closed, it is too late to ask for the dates.

Writing dialogs is more difficult than a window. You might want to consider folding your script into your window code instead of having a script that calls a dialog.

This is a low rent way of doing what you want with the dialog.

import ttkbootstrap as ttk def get_dates(start=None, end=None, format="%Y/%m/%d"): """Draw dialog for selecting start and end dates.""" root = ttk.Window() root.title("Enter Dates") # If window is destroyed we cannot get the date values. # Override what the close button does. root.wm_protocol("WM_DELETE_WINDOW", root.quit) frame = ttk.Frame(root) frame.pack(padx=10, pady=10) ttk.Label(frame, text="Start Date").grid(row=0, column=0, pady=(0, 10)) start = ttk.DateEntry(frame, start_date=start, dateformat=format) start.grid(row=0, column=1, pady=(0, 10)) ttk.Label(frame, text="End Date").grid(row=1, column=0, pady=(0, 10)) end = ttk.DateEntry(frame, start_date=end, dateformat=format) end.grid(row=1, column=1, pady=(0, 10)) done = ttk.Button(frame, text="Done", command=root.quit) done.grid(row=2, column=0, columnspan=2, sticky="news") # Wait until the done button or close decoration are pressed. root.mainloop() # Get dates before destroying the window. start = start.entry.get() end = end.entry.get() root.destroy() return start, end print(get_dates())

The script that used the dialog is just a print() statement, but I think you can see how the dialog would get used in a longer script.
