# ===================== SUMMARY OF time MODULE =====================
# time module is used to work with time-related operations in Python.
# time.time() gives current time in seconds from 1 Jan 1970.
# time.ctime() converts seconds into readable date and time format.
# time.sleep() stops the program for a few seconds.
# time.localtime() gives current local time in structured format.
# time.strftime() formats date/time into our required format.
# time.strptime() converts string date/time into time structure.
# time.perf_counter() is used to measure execution time accurately.
