Example for python logging

logging_sample.py

#!/usr/bin/python3
import logging
# log levels are debug, info, warning, error and critical. Setting e.g. info logs info and above (warning, error, critical)

# logging.basicConfig(level=logging.INFO, filename="logging_sample.log") 

# Basic logging is probably not sufficient. You can and should create your own Logger like this
logger = logging.getLogger('logging_sample')  # Use this name to get the same logger from different submodules
FORMAT = "[%(filename)s:%(lineno)s - %(funcName)5s() ] %(message)s"
logging.basicConfig(format=FORMAT, filename="logging_sample.log", filemode="w")  # default for filemode is append, w = (over)write
logger.setLevel(logging.INFO)


def raw_reading(data):
    logger.info(f"{data}")
    # create and save a image as well
    image_filename = "7589346340.png"
    logger.info(f"![raw_reading Image]({image_filename})") # use e.g. Markdown Syntax here
    return data + [":o"]

if __name__ == '__main__':
    # All documentation is at https://docs.python.org/3/library/logging.html
    logger.debug("This won't be logged, as it's level DEBUG")
    logger.info("# Report Start")
    data = [1, 2, "test", [c for c in "Hallo"]]
    raw_reading(data)
    logger.info("# Report End")
    # Now you could convert the Report to html or something https://github.com/trentm/python-markdown2
