- 10-6. Addition: One common problem when prompting for numerical input occurs when people provide text instead of numbers. When you try to convert the input to an int, you’ll get a ValueError. Write a program that prompts for two numbers. Add them together and print the result. Catch the ValueError if either input value is not a number, and print a friendly error message. Test your program by entering two numbers and then by entering some text instead of a number.arrow_forwardPart 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.arrow_forwardQuestion 2: Write a program to check responses of a student to the multiple-choice final exam. The final exam consists of 20 questions, and answer sheet is abedeabcdeabedeabcde. Your screen should look like: Please, write your answers: abbdeabbdeabbdeabbde Please, write your answers: or aaaaaaaaaaaaaaaaaaaa Your score is 16 out of 20. Your score is 4 out of 20.arrow_forward
- ogramming Languages home-335 LAB Mad Lib-loops Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways Write a program that takes a string and an integer as input and outputs a sentence using the input values as shown in the example below The program repeats until the input string is quit and disregards the integer input that follows Ex If the input is apples 5 shoes 2 quit o the output is Eating 5 apples a day keeps you happy and healthy. Eating 2 shoes a day keeps you happy and healthy. LAB ACTIVITY B 9 3351 LAB Mad Lib-loops 2 #includearrow_forwardChess bishop moves diagonally in any number of squares. Given two different squares of the chessboard, determine whether a bishop can go from the first square to the second one in a single move. The program receives four numbers from 1 to 8 each specifying the column and the row number, first two - for the first square, and the last two - for the second square. The program should output YES if a bishop can go from the first square to the second one in a single move or NO otherwise. Define a function called bishop_move # Example input ```4455``` # Example output ```YES``` #arrow_forward1. 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_forwardMad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away.arrow_forwardHomework write a program that will add the terms of an infinite geometric series. The program should read the first term (a) and the common ratio (r) for the series. It should the compute the sum in two ways: by formula (s=a/1-r), and by adding the individual terms until the answer agrees with the formula to 7 significant digits. The print the formula answer, the answer found by adding terms, and the number of terms that were added. Print the sums to at least ten places. Verify input with a while loop. Two real values are equal to n significant digits if the following condition is true: |a-b|<|a*10^-n| Wrong test - this won't work if r is very near one. Try a=2, r=.99999 With smaller values of r, it is asking for too much precision. With a=2,r=.99, it is getting 10 significant digits. HELP ME FIX CODE.

The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is: 93 the output is: 93 92 91 90 89 88 Ex: If the input is: 77 the output is: 77 Ex: If the input is: 9 or any number not between 20 and 98 (inclusive), the output is: Input must be 20-98 For coding simplicity, follow each output number by a space, even the last one. Use a while loop. Compare the digits; do not write a large if-else for all possible same-digit numbers (11, 22, 33, …, 88), as that approach would be cumbersome for large ranges.arrow_forwardarrow_back_iosarrow_forward_ios
