[Bug]: "Save As" does not ask for a new path when a file is already saved #3321

Describe the bug

Affected script: Simple Python IDE using Tkinter

The save_as() function is supposed to let the user choose a new destination every time it is called. However, when the file has already been saved, the function skips the saving dialog entirely and overwrites the existing file. This makes Save and Save As identical, making the user unable to duplicate or export the file to a different location.

Steps to reproduce the behavior

1. Open any existing file using File > Open.
2. Make any change in the IDE.
3. Click File > Save As.
4. No dialog appears and the original file is overwritten.

Expected behavior

"Save As" should always open a file explorer dialog that lets the user specify a new file name and path, regardless of whether a file is currently loaded. The original file must remain untouched

Additional context

I selected "Linux" as affected OS because I tested the script on Void Linux x86_64, but the issue is the same for the other types of OS.
