Why does Python not release filehandles to log files?

edit

Python does release filehandles to log files, but it depends on how the logging is implemented.

In the basic logging configuration, file handles are released when the program exits. However, if the logging handlers are not closed explicitly or if they are still being used by other parts of the program, this can cause the file handles to remain open.

To avoid this, it is recommended to use the logging module's logging.shutdown() function to release all handlers and flush all logging data before the program exits. This ensures that all file handles are closed and any pending log records are written to the file.

Additionally, one can use the with statement while opening files to ensure that the file handles are closed once the block of code executing inside the with statement exits.

Overall, it is important to properly manage file handles when logging in Python to avoid potential issues with file handling related to log files.
