See also

An alias of sp_logging module, providing logging functionality.

logging.getLogger

Standard library function to retrieve logging.Logger instance. For more: https://docs.python.org/3/library/logging.html

Notes

See Python documentation (https://docs.python.org/3/library/logging.html) for detailed API. Below is only a summary.

The logger has 5 levels of logging from the most serious to the least:

  1. CRITICAL or FATAL

  2. ERROR

  3. WARNING

  4. INFO

  5. DEBUG

  6. NOTSET

The logger has the following methods, based on these logging levels:

  1. critical(msg, *args, **kwargs) or fatal(msg, *args, **kwargs)

  2. error(msg, *args, **kwargs)

  3. warning(msg, *args, **kwargs) or warn(msg, *args, **kwargs)

  4. info(msg, *args, **kwargs)

  5. debug(msg, *args, **kwargs)

The msg can contain string formatting. An example of logging at the ERROR level using string formatting is:

>>> sp.get_logger().error("The value %d is invalid.", 3)

You can also specify the logging verbosity. In this case, the WARN level log will not be emitted:

>>> sp.get_logger().setLevel(sp.sp_logging.WARNING)
>>> sp.get_logger().debug(
...     "This is a debug."
... )  # This will not be shown, as level is WARNING.
>>> sp.get_logger().info(
...     "This is a info."
... )  # This will not be shown, as level is WARNING.
>>> sp.get_logger().warning("This is a warning.")

Examples

Get the root logger from module attr:

>>> from scikitplot import logger
>>> logger.setLevel(logger.INFO)  # default WARNING
>>> logger.info("This is a info message from the sp logger.")

>>> import scikitplot as sp
>>> sp.logger.setLevel(sp.logger.INFO)  # default WARNING
>>> sp.logger.info("This is a info message from the sp logger.")
