Im trying to make a backup utility tool in python where the user can backup either folder or file but not both. The folder can backup folders but for the file, it does not backup the file. It will only produce a log file which state the starting time of backup process and the end time of backup process

I tried modify it but im stuck
>Solution :
The reason why only your folders get backed up, but not you files is because of this line for root, dirs, files in os.walk(source_folder) when you back up. This works as expected when source_folder is a folder, but when source_folder is a file, os.walk doesn’t return anything for you to loop over.
So what you should do is perform a check if you are backing up files or folders. You can do this by using your is_file_selected and is_folder selected. Then the code you have now for backing up your folders goes under is_folder_selected, and for when files are selected you may simply just loop over them.
# Check if we are backing up files or folders
if is_folders_selected:
for source_folder in source_folders:
for root, dirs, files in os.walk(source_folder):
for file in files:
# The same code as before
# ...
if is_files_selected:
for source_file in source_folders:
# Then use almost the same code as in folders
