root_logger.handlers = []
# set the lowest-severity log message to be included by the root_logger (this
# doesn't need to be set for each of the handlers that are added to the
# root_logger later because handlers inherit the logging level of their parent
# if their level is left unspecified. The root logger uses WARNING by default)

# to a log file (the default write mode is append)

In computing, a log file is a file that records either events that
occur in an operating system or other software runs, or messages between
different users of a communication software. Logging is the act of
keeping a log. ... Many operating systems, software frameworks and
programs include a logging system.

# logging
import logging
# log the execution time and a message of an action
logging.basicConfig(filename='fileName.log', level=logging.INFO,	format='%(levelname)s:%(asctime)s:%(message)s',	datefmt="%Y-%m-%d %H:%M:%S")
logging.info('ADD TWO NUMBERS')
print(5+5)
# output in console -> 10
# output in fileName.log -> INFO:2021-12-25 17:47:27:ADD TWO NUMBERS
# Logging is a means of tracking events that happen when some software runs. Logging is important for software developing, debugging and running. If you don’t have any logging record and your program crashes, there are very little chances that you detect the cause of the problem.

# For example usage:

Logging
In many cases it can be useful to print the
response and/or request details in order to
help you create the correct expectations and
send the correct requests. To do help you do thi
s you can use one of the predefined filters
supplied with REST Assured or you can use one of the shortcuts.
Request Logging
given().log().all(). .. //
Log all request specification details
including parameters, headers and body
given().log().params(). .. // Log only the parameters of the request
given().log().body(). .. // Log only the request body
given().log().headers(). .. // Log only the request headers
given().log().cookies(). .. // Log only the request cookies
given().log().method(). .. // Log only the request method
given().log().path(). .. // Log only the request path
