Logging with two handlers - one to file and one to stderr

wish helps you Not exactly sure why this is the case but adding the StreamHandler first causes it to also write to the file. I moved the StreamHandler to after adding the TimedRotatingFileHandler and this resolved the problem.

logging to a file and stderr with a Python logger

Hope that helps Anything equal or worse than WARNING goes to wherever the main program (outside of my control) has configured the logging to go (usually stderr) Everything else (debug messages mainly) go to a log file
You can't do it with a single logger without setting WARNING level on ancestor's handlers. From the docs:
Logger.propagate
import your_module # in the main application

your_module.get_logger().log_to_file(filename) # without this line your module
                                               # shouldn't create debug files
...
your_module.some_function()

like below fixes the issue The reason there are two different ways is due to New Features in J2SE 5.0. In J2SE 1.4, you could only add handlers to the root logger using the handlers property.
Per the Java 1.4 LogManager JavaDocs:

Python capturing stdout/stderr and logging to file while seeing output

I wish this help you Easiest way for me was the answer from jww. Use tee in the python script in conjunction with os.system and tee -a if you need to append the output of another script to the same logfile.
test_script.py
import os


def main():
    cmd1 = "path/to/aribitrary_script | tee /path/to/logfile"
    cmd2 = "path/to/another_script | tee -a /path/to/logfile"

    os.system(cmd1)
    os.system(cmd2)


if __name__ == '__main__':
    main()
