An intuitive timer.

It is currently undergoing rapid iteration. If you encounter any issues with its functionalities, feel free to raise an issue.

Installation

You can install spinesUtils from PyPI:

pip install spinesUtils

Logger

You can use the Logger class to print your logs without worrying about handler conflicts with the native Python logging module.

This class provides log/debug/info/warning/error/critical methods, where debug/info/warning/error/critical are partial versions of the log method, available for use as needed.

# load spinesUtils module
from spinesUtils.logging import Logger

# create a logger instance, with name "MyLogger", and no file handler, the default level is "INFO"
# You can specify a file path `fp` during instantiation. If not specified, logs will not be written to a file.
logger = Logger(name="MyLogger", fp=None, level="DEBUG")

logger.log("This is an info log emitted by the log function.", level='INFO')
logger.debug("This is an debug message")
logger.info("This is an info message.")
logger.warning("This is an warning message.")
logger.error("This is an error message.")
logger.critical("This is an critical message.")

2024-01-19 15:02:51 - MyLogger - INFO - This is an info log emitted by the log function.
2024-01-19 15:02:51 - MyLogger - DEBUG - This is an debug message
2024-01-19 15:02:51 - MyLogger - INFO - This is an info message.
2024-01-19 15:02:51 - MyLogger - WARNING - This is an warning message.
2024-01-19 15:02:51 - MyLogger - ERROR - This is an error message.
2024-01-19 15:02:51 - MyLogger - CRITICAL - This is an critical message.
