How to save data entered in tkinter

I would like to use tkinter in python to save the data I entered or referenced.
If you look it up online, there is a way to save it using sql, but is there any other way?

What you want to achieve
Click on the image in the script below.

画像 Image acquisition>Save
②Select the image you saved in the folder
③Click Image

If you close the tkinter and reopen it, the data in the selected folder will disappear.
That's why
Is there any new function or other way to save the file on tkinter?

フォ Select the image saved in the folder
Can I see the selected folder after re-opening tkinter?
I'd like to save the folder I finally selected.

May I have your advice?

I would appreciate it if someone could teach me.
Thank you for your cooperation.

If you only need one piece of data, it's easy to read it at startup and update the files every time the data is updated.

If you extract and describe only the relevant parts, it will be as follows.Skip the front and back.

###Retrieve data from the file where the selected file path is stored (change the name and folder appropriately)
savedata_file=os.path.dirname(os.path.abspath(__file__))+'\\savedata.txt'
try:
    with open(savedata_file, 'r', encoding='utf8') asf:
        selected_file=f.read()
except:
    selected_file="C:\\python_test\\*.*"#If the file is missing, the initial folder + dummy filename

# Browse files, run when button is clicked
def file_select():
    global selected_file
    idir=os.path.dirname(os.path.abspath(selected_file))### Extract destination folder
    filetype=[("All", "*"), ("Text", "*.txt"), ("Music", "*.mp3")]# Select Extension
    file_path=tk.filedialog.askopenfilename (filetypes=filetype, initialdir=idir)
    selected_file=file_path
    input_box.insert(tk.END, file_path)#View Results
    print(selected_file)
    #### Save to file if selection path is valid
    ifos.path.exists(selected_file):
        with open(savedata_file, 'w', encoding='utf8') asf:
            f.write(selected_file)

Here is no example, but other methods are also available:

If you want to add a little more data and tie it up, you can use this package.
