Examples To Use Python Logger

Python Logger is very easy to use!

from Logger import Logger

inst = Logger()   # or you an use Logger.get_instance() for first time also

inst.debug("String", 21, 98.8776768787, 48, True, False)
inst.error("String", 21, 98.8776768787, 48, True, False)
inst.info("String", 21, 98.8776768787, 48, True, False)
inst.trace("String", 21, 98.8776768787, 48, True, False)


sameInst = Logger.get_instance()


sameInst.debug("String", 21, 98.8776768787, 48, True, False)
sameInst.error("String", 21, 98.8776768787, 48, True, False)
sameInst.info("String", 21, 98.8776768787, 48, True, False)
sameInst.trace("String", 21, 98.8776768787, 48, True, False)

The log file generated in the “logs” folder.

Note:- In console, output comes with different color code of each log level. It is not observable in ipynb files.

inst.disable_all_logs()
inst.debug("Logs are disable, so these logs are not visible")
inst.error("Logs are disable, so these logs are not visible")
inst.info("Logs are disable, so these logs are not visible")
inst.trace("Logs are disable, so these logs are not visible")

inst.enable_all_logs()
inst.debug("Logs are enable, so these logs are visible")
inst.error("Logs are enable, so these logs are visible")
inst.info("Logs are enable, so these logs are visible")
inst.trace("Logs are enable, so these logs are visible")

inst.get_current_log_level()

6

6 represent enable logs.

Now, change the log level to 2.

inst.update_log_level(2)
inst.get_current_log_level()

2

Only Error logs will be visible.

inst.debug("Logs are enable, so these logs are visible")
inst.error("Logs are enable, so these logs are visible")
inst.info("Logs are enable, so these logs are visible")
inst.trace("Logs are enable, so these logs are visible")

m2023-03-07 18:49:53.538029 [ERROR] Logs are enable, so these logs are visible

Now, Change the log level to 3, upto trace logs will be visible.

inst.update_log_level(3)
inst.get_current_log_level()

3

inst.debug("Logs are enable, so these logs are visible")
inst.error("Logs are enable, so these logs are visible")
inst.info("Logs are enable, so these logs are visible")
inst.trace("Logs are enable, so these logs are visible")
