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?

Answer 1

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)

• dylanvanw: What would be the handler in the example of the question that must be closed?
• Nixinova: If handlers is empty replace the first self.log with logging.getLogger() instead of logging.getLogger(__name__).

Answer 2

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