[Tkinter] logical error - saving file

[rwahdan]

There is a simpler way to check.
If you use pathlib to open files, you can use:

from pathlib import Path
import os

# make sure in proper directory (this sets dir same as script)
os.chdir(os.path.abspath(os.path.dirname(__file__)))

# example file
filename = Path("myfile.txt")

if filename.stat().st_size:
   print("file has size")
else:
    print("file is empty")

if not using pathlib, use instead:

import os

# make sure in proper directory (this sets dir same as script)
os.chdir(os.path.abspath(os.path.dirname(__file__)))

# example file
filename = "myfile.txt"

if os.stat("myfile.txt").st_size:
    print("file has size")
else:
    print("file is empty")

Thanks for the big help
