Python Logging Error

So I'm using the python logging module for the first time, and I'm receiving an error I cannot find any information on.

At the start of my file, I have the following:

logging.basicConfig(level=logging.INFO, filename='logs', filemode='a+', format='[%(asctime)-15s] %(levelname)-8s %(message)s')

The line that's throwing the error:

logging.info(f'Downloading: {file_name}\t{local_file_path}\t{os.path.abspath(local_file_path)}')

--- Logging error ---
Traceback (most recent call last):
  File "C:\Python36\lib\logging\__init__.py", line 996, in emit
    self.flush()
  File "C:\Python36\lib\logging\__init__.py", line 976, in flush
    self.stream.flush()

I don't understand this error. The first 8 times it ran successfully without a problem. However the last two, it has thrown this identical error. Can someone please explain it to me.

The fact that it failed on a self.stream.flush() implies that the file being written to (presumably logs) has already been closed or is not writable for some other reason.

Update: If you need to deal with this, subclass the handler and override the emit() method to do what you need to recover from the error.
