as environment variable in DockerFile.
Can you please help?

See Question&Answers more detail:osSetting PYTHONUNBUFFERED
to a non empty value ensures that the python output is sent straight to terminal (e.g. your container log) without being first buffered and that you can see the output of your application (e.g. django logs) in real time.
This also ensures that no partial output is held in a buffer somewhere and never written in case the python application crashes.
