(This is a better version of an exercise from Chapter 1.) A government research lab has concluded that an artificial sweetener commonly used in diet soda pop causes death in laboratory mice. A friend of yours is desperate to lose weight but cannot give up soda pop. Your friend wants to know how much diet soda pop it is possible to drink without dying as a result. Write a

- You have been asked to write a program to play rock-paper-scissors. Your program will ask the user to input a number 0, 1, or 2 to denote rock, paper, and scissors respectively. Your program will then randomly generate a number 0, 1, or 2 to denote the computer’s hand. The rules for the game are: •A scissor can cut paper. •A rock can knock a scissor. •A piece of paper can wrap a rock. Let the game run continuously until either the user or the computer wins 3 times, displaying the outcome of each hand. At the end of the game, display a message indicating whether the user or the computer wins Helpful Hint: import random player2= random.randint(0, 2)arrow_forward.

You will write a program that randomly generatesan integer between 0 and 100, inclusive. The program prompts the user to enter a number continuously until the number matches the randomly generated number.

- A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write a program that calculates and prints the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a neat tabular format and should calculate and print the total of yesterday’s receipts. The program should use the function calculateCharges to determine the charge for each customer. Your outputs should appear in the following format Sample output Enter the hours parked for 3 cars: 1.5 4.0 24.0 Car Hours Charge 1 1.5 2.00 2 4.0 2.50 3 24.0 10.00 TOTAL 29.5 14.50arrow_forwardAn instructor gives a series of exams during the semester in her math class. At the end of the semester she drops each student's lowest test score before averaging the scores. She has asked you to design a program that will read a student's test scores as input and calculate the average with the lowest score dropped. Here is the algorithm that you developed: Get the student's test scores. Calculate the total of the scores. Find the lowest score. Subtract the lowest score from the total. This gives the adjusted total. Divide the adjusted total by 1 less than the number of test scores. This is the adjusted average. Display the average. The test scores are in a text file named scores.txt and contains the following: Mickey, 71.0, 42.0, 83.0 Donald, 94.0, 73.0, 72.0, 81.0 Minnie, 95.0, 85.0, 45.0, 55.0, 65.0 A sample run is as follows: Enter a file containing floating point numbers: scores.txt Test scores for Mickey: ['71.0', '42.0', '83.0'] Removed the lowest score of 42.0 for Mickey The…arrow_forwardGiven the sample code above in generating a random number. Create a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 13. The computer's choice is displayed. 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissor wins. (Scissors cuts paper.) c. If one player chooses paper and the other player…arrow_forward
- Write a program in python Suppose a right triangle is placed in a plane as shown below. The right-angle point is at (0, 0), and the other two points are at (200, 0), and (0, 100). Write a program that prompts the user to enter a point with x- and y-coordinates and determines whether the point is inside the triangle. Sample runs of the program are given below: Enter a point's x- and y-coordinates: 100.5 25.5 The point is in the triangle Enter a point's x- and y-coordinates: 100.5 50.5 The point is not in the trianglearrow_forwardA parking garage charges a $20.00 minimum fee to park for up to three hours.

This will give you practice with random numbers and loops while allowing you to explore and understand a little more Java code. You will also need to test out this program to ensure the correctness of the algorithm and code. You will need to develop test data that will represent all possible kinds of data that the user may enter. You are going to write a program that allows the user to play a simple guessing game in which your program thinks up an integer between 1 and 100 and allows the user to make guesses until the user gets it right. (The program also counts how many tries it took to get the correct number). For each incorrect guess you will tell the user whether the right answer is higher or lower. Your program is required to exactly reproduce the format and behavior of the log of execution. Program should output: (Sample user output written in bold) This program…arrow_forward
- 1. Write a pyrhon program that prints out a classic hangman stick figure. The program should ask the user to enter a number from 1-6 and the corresponding hangman should be printed. The value the user inputs corresponds to the number of incorrect guesses in a real hangman game and so the completeness of the hangman will correspond to the number of ‘incorrect guesses’ inputted by the user (e.g., if the user enters 1, then only the head of the hangman will be printed; full example below). Example:Enter a number from 1-6: 1O Enter a number from 1-6: 2O|Enter a number from 1-6: 3O\||Enter a number from 1-6: 4O\|/|Enter a number from 1-6: 5O\|/|/Enter a number from 1-6: 6O\|/|/ \ 2. Modify your program from problem 1 so that the user input is checked to be a validsingle digit (1-6) before printing the corresponding hangman. If the input is not valid, theninstead of a hangman the following message should be printed “Invalid input: you must enter asingle number from 1-6.” Example:Enter a…arrow_forwardThe equation of a straight line is written as y = mx + b where m is the slope of the line and b is the value of y when x = 0. If there are two coordinate points of the line are given, then it is very easy to compute the line equation. Also you can find the distance between two points. Problem: Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4. Compute the distance between two points using…arrow_forwardTask 9 Write Python code of a program that reads an integer, and prints the integer if it is a multiple of NEITHER 2 NOR 5.
