Homework 2: More Simple Functions Solution

The goal of this assignment is continue practicing writing and testing functions. You should




work individually on this assignment.




Getting Started



You should start by creating a folder specically for this assignment. Create a README.txt le including three things: your name, the course name, and the name of this assignment. You should also use it answer any questions that may be asked in this assignment along with including any comments that you want the grader to consider when grading your assignment. You should not




include any code in your README.txt le.




More Functions



Following the same process as we did in Lab 2, you will design, implement, and test the following functions. You should start by downloading the provided 2019spring-cs5001-homework02-StarterFiles.sip archive provided on Bottlenose and extract the moreFunctions.py and moreFunctionsTest.py les into the folder that you created specically for this assignment. You should modifying these les.




2.1 Function: printFlag




Design and implement a function called printFlag that can print a

ag. Your implementation should be implemented in such a way that it only prints single characters: ` *' , `R', and ` ' (space). The pattern should match the following exactly:




* * * * RRRRRRRRRRRRRRRRRRR



****



* * * * RRRRRRRRRRRRRRRRRRR



****



RRRRRRRRRRRRRRRRRRRRRRRRRRRRR




RRRRRRRRRRRRRRRRRRRRRRRRRRRRR




RRRRRRRRRRRRRRRRRRRRRRRRRRRRR




Hint: each line is 30 characters long in total.




Since this function is not doing much other than printing the

ag, testing is a lot less interesting, but it provides us a way to run the code in an automatic way. Your Given-When-Then could read:




Given : --




When : printFlag is called




Then : a flag is printed to the screen and is visually inspected

2.2 Function: star




Design and implement a function called star that could be used instead of the * operator. Your function should have two parameters that represent the two operands of the * operator. Hint: remember that the * operator works for both numeric and string values.




2.3 Function: reformatName




Design and implement a function called reformatName that will receives two strings values that representing someone's rst and last name. Your function should return a single string containing the rst name that is all lower case except for the rst letter, a space, and the last name in all upper case.




Testing this function will take a little bit more e
ort. You will want to think about the di
erent combinations of capitalization that are possible and write a di
erent test for each combination.




Hint: Strings are highly versatile because they come with a bunch of di
erent functions already dened. For example, if you have a string called s, you can use it to change the case of the letters in a string by using s.capitalize() , s.lower, s.swapcase() or s.upper(). You will need to use two of these functions for this problem, experiment to see what each one does.




Submit Files to Bottlenose



Before submitting, be sure that you have added a comment at the top of your source les that includes your name and the current date. Then create an archive of the folder that you created for this assignment containing all of the les that you have created and upload this archive to Bottlenose for grading. When you upload, be sure to check whether there are any auto-graders that evaluated your code. When you have xed any issues pointed out by the auto-graders and are completely satised with your submission, you should complete the Homework 2 Review questions.
