To print output to the Docker logs in Python,
you can use the print() function and redirect the output to the sys.
stderr file object.
The sys.stderr file object is a standard error stream that is used to write error messages and other output that should not be buffered.

Here is an example of how you can use print() to write to the Docker logs in Python:

Copy code
import sys

# Print a message to the Docker logs
print("This is a message for the Docker logs", file=sys.stderr)
You can then view the Docker logs using the docker logs command.
For example:

Copy code
$ docker logs <container_id>
This will display the logs for the specified Docker container. You should see the message that you printed using print() in the output.

Note that the print() function writes to the standard output stream by default.
To write to the standard error stream,
you need to specify the file parameter and set it to sys.stderr.

It is generally a good practice to use the sys.stderr file object to write error messages and other output that should not be buffered,
as this can help you troubleshoot issues with your Docker container and make it easier to identify problems in the logs.
