Description
Question 1. Write a program to ask the user to enter 3 integers and then display a multiplication equation. Your code must work exactly like the following example (except the text in bold which indicates the user input): Please enter the 1st integer: 2 Please enter the 2nd integer: -5 Please enter the 3rd integer: 20 Display equation using string addition: 2 x -5 x 20 = -200 Important requirement: Your program must use string addition to produce the exact output as illustrated in the above example. You may assume the input are integers. Question 2. Write a program to ask the user to enter 2 subject details and then display this information using string format – <class ‘str’>.format(). Your code must work exactly like the following example (the text in bold indicates the user input): Enter the 1st subject code: MATH 101 Enter the 1st subject title: Linear Algebra Enter the 1st subject credit point: 9 Enter the 2nd subject code: CS 203 Enter the 2nd subject title: Data Structure with Java Enter the 2nd subject credit point: 10 Your chosen subjects: MATH 101: Linear Algebra CS 203: Data Structure with Java Total credit points: 19. Important requirement: – Your program must use format – <class ‘str’>.format(). to produce the exact output as illustrated in the above example – You should test your program for different input values Question 3. At the Singapore Zoo, each adult ticket costs $ 39, each child (>= 3 years old, <= 12 years old) ticket costs $26.50 and each young child (< 3 years old) ticket is free. Write a program to ask the user to enter the number of tickets for each type and then display the ticket information. Your code must work exactly like the following example (the text in bold indicates the user input): How many adult tickets you want to order: 2 How many children (3-12 years old) tickets: 3 How many children (<3 years old) tickets: 2 Type Number of tickets Cost Adult 2 $78.00 Children (3-12y.o.) 3 $79.50 Children (<3) 2 free Total 7 $157.50 Important requirement: Your program must use string format to produce the exact output as illustrated in the above example (including the alignment – 20 characters, 17 characters, 15 characters, dollar signs and 2 decimal places in cost). You should test your program for different integer values as input Question 4. A subject has 3 assessments: – An assignment whose mark is an integer between 0 and 20; – A project whose mark is an integer between 0 and 30; – A final exam whose mark is an integer between 0 and 50. – There are 4 possible grades: A, B, C and Fail. The grade is determined by the following rules: Marks Grade Final exam mark = <20 Fail Total mark >= 90 A Total mark >=75 B Total mark >=60 C Total mark <60 Fail Question 4. Enter your assignment mark: 20 Enter your project mark: 17 Enter your final exam mark: 15 Your result: Assignment: 20 Project: 17 Final exam: 15 Grade: Fail Important requirement: – Your program must use string format to produce the exact output as illustrated in the above example. 22 characters for the first column and 4 characters for the results. – You should test your program for different kind of scenarios, here are some examples for testing: – Assignment 11, Project 20, Final exam 19, Grade Fail – Assignment 11, Project 20, Final exam 41, Grade C – Assignment 13, Project 20, Final exam 28, Grade C – Assignment 18, Project 20, Final exam 37, Grade B – Assignment 10, Project 18, Final exam 49, Grade B – Assignment 18, Project 26, Final exam 48, Grade A Question 5. Jimmy downloaded a large number of poorly named files, e.g. “cute_cat[20150203].jpg”, “[quick]brown_fox.png”, “[x264]lazy_dog[1280×720].mp4” and would like to automatically clean up these filenames by removing all instances of square brackets and the contents contained within. Write a Python script that: 1. Prompts for filenames with “Filename?” repeatedly, until an empty string is given 2. Prints a string with all the cleaned filenames, separated by commas Question 5. Filename? cute_cat[20150203].jpg Filename? [quick]brown_fox.png Filename? [x264]lazy_dog[1280×720].mp4 Filename? cute_cat.jpg,brown_fox.png,lazy_dog.mp4 Important requirement: – Your program must use string format to produce the exact output as illustrated in the above example. With commas separation in between the first and last file names You should test your program for different kind of scenarios
