I need an explanation as well. You can mention that in the Python file as well. Please mention Problem 1, problem 2, problem 3 and problem 4
1811/2807/7001ICT Programming Principles, Trimester 1, 2021 Workshop 6 School of Information and Communication Technology Griffith University April 21, 2021 Module 2 When Workshop 6 Goals This workshop focusses on lists, indexing, slices, list methods, and/or tuples. Marks 5 Due Both pre-workshop and workshop tasks shall be submitted online using the submission links. Pre-workshop questions are due before the start of this workshop; Workshop activity problems are due by the start of the next workshop. 1 Preparation Before your workshop class: Read all of this document. Review the lecture notes sections 1 to 17. Complete and submit the pre-workshop questions (1 mark). Bring some paper (a print-out of this document is best) and writing implements. Bring a storage device, such as a portable hard drive and cable, or a USB drive. 2 Electronic submission Based on the feedback from students, we are moving to electronic submission and marking of workshops. This means you don’t need to show your code for marking in the workshop anymore. Please submit separate files with names “problem1.py”, “problem2.py, ..., using the submission link. Write sufficient comments in the files to help understanding of your codes. 3 Workshop activities 3.1 Problem 1 (1 mark) Problem: Write a program that reads strings (without digits or symbols in the string) typed by the user until an empty string is entered. For each string, convert all words to lowercase, then sort and print the words into descending order lexicographically. Enter a string: Three Rings for the eleven kings under the sky Output: under three the the sky rings kings for eleven Enter a string: Seven for the Dwarf lords in their halls of stone Output: their the stone seven of lords in halls for dwarf Enter a string: Nine for Mortal Men doomed to die Output: to nine mortal men for doomed die 1 Enter a string: One for the Dark Lord on his dark throne Output: throne the one on lord his for dark dark Enter a string: In the land of Mordor where the Shadows lie Output: where the the shadows of mordor lie land in Enter a string: Hint: use split function to split a string into a list, then sort it with a method. 3.2 Problem 2 (1 mark) Problem: Write a program that allows the user to enter two lists of integers, calculate the sum of the first and the last integers in each list, and print the larger sum. In the event of a tie, print Same. When there is only one integer in the list, the sum is the integer itself. For example: List 1: 1 2 3 4 5 List 2: 5 6 7 Output: 12 List 1: 4 3 10 1 List 2: 9 Output: 9 List 1: 4 3 2 1 List 2: 1 2 3 4 Output: Same 3.3 Problem 3 (1 mark) Problem: We’ll say that a lowercase ’g’ in a string is ”happy” if there is another ’g’ immediately to its left or right. Write a function to print True if all the g’s in the given string are happy, otherwise, print False. String: xggt Happy?: True String: abgsx Happy?: False String: g Happy"? False String: brggsomr Happy?: True 3.4 Problem 4 (1 mark) Problem: Write a program that allows the user to enter the marks of 5 students in 4 courses, Output the highest average marks for students and courses. For example: Student 1 (courses 1-4): 50 60 70 60 Student 2 (courses 1-4): 100 90 87 90 Student 3 (courses 1-4): 70 100 90 90 Student 4 (courses 1-4): 30 65 50 50 Student 5 (courses 1-4): 58 50 74 43 The highest average mark of students: 91.75 The highest average mark of courses: 74.2 Consider 2 dimensional lists, i.e. the element of a list is a list. 2 4 After the workshop You have created programs that might be useful to refer back to in future workshops. Make sure that you will have that work in the future. One copy is not enough for at IT professional. You should have at least 2 copies: 1. on your Griffith network storage drive; and 2. on your portable storage device. 3 Preparation Electronic submission Workshop activities Problem 1 (1 mark) Problem 2 (1 mark) Problem 3 (1 mark) Problem 4 (1 mark) After the workshop
