Python: can't delete file after logging to

Question

I'm writing to log file using the following code:

import logging
from gmplot import gmplot
logging.basicConfig(filename="sample.log", level=logging.INFO)
logging.debug("This is a debug message")
logging.info("Informational message")
logging.error("An error has happened!")

But then it's impossible to delete this file. how can I 'release' this file?

You need to close() your logging:

As explained there: python does not release filehandles to logfile

When your Run class completes, call:

handlers = self.log.handlers[:]
for handler in handlers:
    handler.close()
    self.log.removeHandler(handler)

What would be the handler in the example of the question that must be closed? – dylanvanw Apr 23 '20 at 08:40
If `handlers` is empty replace the first `self.log` with `logging.getLogger()` instead of `logging.getLogger(__name__)`. – Nixinova Feb 07 '21 at 02:19

simply use logging.shutdown(), when you are done with logging.
