Near Hundred

Purpose: Expand your knowledge of Java by learning
about boolean logic.
* Given an int n, return true if it is within 10 of 100 or 200.
* Note: Math.abs(num) computes the absolute value of a number.
*
* nearHundred(93) → true
* nearHundred(90) → true
* nearHundred(89) → false

Back Around

  /* Instructions: 
  * 
  * Given a string, 
  * take the last char and 
  * return a new string with 
  * the last char added at the 
  * front and back, so "cat" yields "tcatt". 
  * The original string will be length 1 or more. 
  * 
  * backAround("cat") → "tcatt" 
  * backAround("Hello") → "oHelloo" 
  * backAround("a") → "aaa" 
  * 
  * 
  * Note: your value for this exercise will be different based on your seat number

New Assignment (Mr. Cusack will talk about this more in class)

Purpose: Verify new Cyber Range id and password. Also, practice python.

Run this in interactive mode.

Starting screen recording for this sessions.
Name of saved file: PX_Interactive_lastname.mp4 (Video of you running the program)
Be sure to drop these off into google classroom.

Split the program into two parts
Half way into the program.
run the commands below
 
1. print("Hello my name is Joe Cusack") 2. x = 5 3. y = 8 4. z = -34 5. m = x + y + z 6. print("The value of x is: " + x) 7. print("The value of y is: " + y) 8. print("The value of z is: " + z) 9. print("The value of m is: " + m) 10. if m > 0: 11. print("Positive number") 12. else: 13. print("Negative number") l4. for i in range(10) 15. print("Value of i" + i) 16. greet("Hello World") 17. my_list = [20, 18, 16, 14, 12] 18. text = "awesome" 19. print(text.upper()) Insert bottom part for time. use nano to create a python file. example nano PX_rockPaper_lastname.py Be sure to create the following files: PX_rockPaper_lastname.py (Actual python program) PX_rockPaper_lastname.txt (Copy of python program (use google docs)) PX_rockPaper_lastname.png (Screen shot of program running) PX_rockPaper_lastname.mp4 (Video of you running the program) Be sure to drop these off into google classroom. Source code: from random import randint #create a list of play options t = ["Rock", "Paper", "Scissors"] #assign a random play to the computer computer = t[randint(0,2)] #set player to False player = False while player == False: #set player to True player = input("Rock, Paper, Scissors?") if player == computer: print("Tie!") elif player == "Rock": if computer == "Paper": print("You lose!", computer, "covers", player) else: print("You win!", player, "smashes", computer) elif player == "Paper": if computer == "Scissors": print("You lose!", computer, "cut", player) else: print("You win!", player, "covers", computer) elif player == "Scissors": if computer == "Rock": print("You lose...", computer, "smashes", player) else: print("You win!", player, "cut", computer) else: print("That's not a valid play. Check your spelling!") #player was set to True, but we want it to be False so the loop continues player = False computer = t[randint(0,2)]
