I have a question, do most people think python3_pid_ts.log is a normal log file name? If yes, I think we can add an extra argument to generate a custom prefix name for log file, otherwise the python3 should be replaced with another name. (e.g. the filename of __main__).

I am not sure if users would like to add this argument for most python executable in a launch file.

otherwise the python3 should be replaced with another name. (e.g. the filename of main).

yeah we can do that. maybe we can discuss on what could be default name when we get an executable name with python3. but here we just give the capability for user to change the log name as they like. i thought that can be more flexible for user. thanks for the review.
