7. Create timestamp decorator. Instructions: • Create a file named log.py and create decorator inside called timestamp • The decorator should print the current time then afterwards print anything the is being decorated (see examples below) Hint: - Use time.ctime() Examples: Input (in file called test.py): from log import timestamp Otimestamp def hi(): print('hi') def main(): hi() main () Output: $ python3 test.py Wed Oct 19 17:27:12 2022 hi

1. Random numbers File: random_numbers.py (Quick note: NEVER name your files the same as a Python module. If you call this file random.py it won't let you import the real random.) (Another quick note: Don't let yourself get stuck on something for too long. If one part of one question starts taking you too long, just leave it, move on and come back to it later.) Write a complete Python program that ask the user for quantity of random numbers and a maximum, then generates and store that many numbers between 0 and the maximum. When you've got this part working, add the following interesting additions: minimum maximum random choice from existing list (Hint: if there are 7 numbers it will be a number at a random index 0-6) the list reversed* the list sorted* Note*: Python's .reverse() and .sort() list methods do NOT return the reversed or sorted list... they modify the list in place.So, if you write something like: print(numbers.sort()) You will not get what you expect. You'll sort the…

The Spring fork amateur golf club has a tournament every weekend. The club president has asked you to design a program. It contains the following menu: Select the task 1. Add new records 2. Read Records 3. End the program If the user enters 1, the program will read each players name and golf score as keyboard input, then save the records in a file names golf.dat If the user enters 2, the program reads the records from the golf.dat file and displays them. While the menu selection is not equal to 3, get the user selection. If the selection is 1, get the number of players in the tournament, open the output file. For each player, get the name and the score, and write them to the file. Close the file. If the selection is 2, open the input file, read the values from the file, display the values, close the file. If the selection is 3, exit the program. I already had a code written from before, but I'm having a hard time turning it into a menu driven code. It does need to have the function…
CODE IN PYTHON PLEASE The objective is to create a code in Python that can extract the columns highlighted in blue (Column T and AB3) and output them to a .txt file. The code should be able to generate the text file with the columns that are highlighted in blue and store them on a separate folder. Below shows how the Test.xlsm file looks like as well as how the text file should look like when the code extracts and outputs it.

Task 3: Summary We would like to be able to generate a summary for each logfile to give us a rough idea of its contents. Instructions Create a file called Summary.java. As with Task 1, open the file for reading in a try-catch block. Read through the entire file, counting how many of each message/event type occurs. Print out a summary with the count of each event/message type. As a sanity check: the total number of message/event type counts should equal 1000. Hint: a useful method could be String.split. Sample Input/Output Example 1: Summary -------------------- Notifications: 322 Warnings: 326 Errors: 352 Cannot find logfile! Exiting...
