Part 1: Complete the survey. Part 2: Peek-a-boo is a fun game that little kids like to play. To simulate this game on the computer, write a program that will generate a random number between 1 and 4. Then, will print to the screen the animal name associated to that number. The animal names used will be: pig when a 1 is generated cow when a 2 is generated chicken when a 3 is generated horse when a 4 is generated If your program generates a 3, the output will be: chicken The player will then enter a 1 if they would like to play again or anything else to exit the program. If the player enters "1 1 1 0", the output will be: horse chicken cow horse For coding simplicity, follow each output animal by a space, even the last one. Hint: To make testing easier, seed your random number generator with 0.
Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the rectangle centred at (1, 1)with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4)is outside the rectangle, as shown in Figure . (Hint: A point is in the rectangleif its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its verticaldistance to (0, 0) is less than or equal to 5.0 / 2. Test your program to cover allcases.) Here are two sample runs. Enter a point with two coordinates: 2 2 ↵EnterPoint (2.0, 2.0) is in the rectangle
Write a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and then generate a new random number so the game can start over.Optional Enhancement: Enhance the game so it keeps count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses.
Write a program that generates a random number in the range of 1 through 1000, and asks the user to guess what the number is. If the user guess is higher than the random number, the program should display Too high, try again. If the users guess is lower than the random number, the program should display Too low, try again. If the user guesses the number, the application should congratulate the user and generate a new random number so the game can start over. If the user doesn't want to continue the game the user should type an appropriate stop symbol to terminate the program (such stop conditions were discussed in the class). For each game iteration, count the number of guesses made by the user and display them. The program should contain the following functions: check_guess(): this function checks if the user's guess is lower, higher or equal to the random number. random_gen(): function that generates one random number for one game iteration main(): the function where the program…
ShowCurrentTime.py, gives a program that displays the current time in GMT. Revise the program so that it prompts the user to enter the time zone in hours away from (offset to) GMT and displays the time in the specified time zone.
Prime factors of an integer \( n \) are a set of prime numbers that can be multiplied together to obtain \( n \). Write a proHide Transcribed Text Prime factors of an integernare a set of prime numbers that can be multiplied together to obtainn. Write a program that asks the user to enter a number and displays the prime factors ordered from smallest to largest. If the number entered by the user is less than 2 then there are no prime factors and the message "No prime factors" should be displayed. The following algorithm can be used to discover the prime factors: - initialize factor to 2 - while factor is less than or equal tondo: ifnis evenly divisible by factor then - conclude that factor is a factor ofn- dividenby factor using floor division else: - increase factor by 1 Adapt the algorithm so it can be used to print out the prime factors of a number. Notes: - You can assume that the number entered by the user will be an integer number. - The output must be in the format shown in the…
A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. examples: magicDate(6, 10, 60) -> truemagicDate(50, 12, 600) -> false

The text presented the Sierpinski triangle fractal. Inthis exercise, you will write a program to display another fractal, called the Kochsnowflake, named after a famous Swedish mathematician. A Koch snowflake iscreated as follows:1. Begin with an equilateral triangle, which is considered to be the Koch fractalof order (or level) 0, as shown in Figure a.2. Divide each line in the shape into three equal line segments and draw an outwardequilateral triangle with the middle line segment as the base to create aKoch fractal of order 1, as shown in Figure b.3. Repeat Step 2 to create a Koch fractal of order 2, 3, . . . , and so on, as shownin Figures c and d.
LAB ASSIGNMENTS, CONT. 2. sandwich.py - follow the instructions below. You may adjust the food items to include your personal favorites. • It uses all of our standard mipo_ex features. • The menu should have numbered or letter options. Sandwich Maker Write a program that asks users for their sandwich preferences. The program should use PylnputPlus to ensure that they enter valid input, such as: Using inputMenu() for a bread type: wheat, white, or sourdough. Using inputMenu() for a protein type: chicken, turkey, ham, or tofu. Using inputYesNo() to ask if they want cheese. If so, using inputMenu() to ask for a cheese type: cheddar, Swiss, or mozzarella. Using inputYesNo() to ask if they want mayo, mustard, lettuce, or tomato. Using inputlnt() to ask how many sandwiches they want. Make sure this number is 1 or 120 00T 110 more. Come up with prices for each of these options, and have your program display all the choices and their prices plus a total cost at the very end. 3 130
Create an application that generates a histogram so you can examine the frequency distribution of a collection of values visually. A random number of integers between 1 and 100 inclusive should be entered into the programme. After that, it should generate a chart like the one below, showing how many input values went between 1 and 10, 11 to 20, and so on.For each number entered, print one asterisk. 1 - 10 | ***** 11 - 20 | ** 21 - 30 | ******************* 31 - 40 | 41 - 50 | *** 51 - 60 | ******** 61 - 70 | ** 71 - 80 | ***** 81 - 90 | ******* 91 – 100 | ********
