Assignment Overview

This lab relates to the material in Chapter 5 – Functions. The purpose of this lab is to implement appropriate functions.

Deliverables

Be sure and include the following required identification information at the top of the program code using comment statements (see Section 2.4 Comments on page 39):

• Name
• 9-Digit ID Number
• Due Date
• Date Submitted
• Brief description of application

Python (.py) file named with the required naming convention, required identification information, and meeting the requirements of the problem statement provided under Activity Details.

Activity Details

Perform the following tasks:

• Step 1: Create a Python (.py) file using IDLE (see Appendix B – Introduction to IDLE) using the required naming convention for Lab 05: CourseNumber_LastNameFirstInitial_LabNumber (e.g., 5390_SharpJ_Lab05)

Place the required identification information in Comment statements (see Section 2.4 Comments on page 39) at the top of the Python program. Within the body of the program implement the following requirements as described in the problem statement below:

Program Statements:

Ms. Sally Jones, a local high school teacher, has hired you to create a modularized program that will allow her to enter three test scores (assume whole numbers will be entered) and calculate a student’s test score average (assume the result will be a whole number – see Table 2-3, page 54) and then determine student’s letter grade and then display the student’s test score average and letter grade. The input of the test scores and the output of the test score average and letter grade will be contained in the main menu. The program should allow Ms. Jones to enter as many students as desired by prompting her if she wants to continue (see 4.2 The while Loop: A Condition-Controlled Loop, page 160-161).

The following functions MUST be implemented:

• calc_average – this function should accept three test scores as arguments and return the average of the scores

• determine_grade – this function should accept the average test score and return a letter grade for the average test score based on the following grading scale (see page 258, Returning Strings):

Score Letter Grade

90-100 A

80-89 B

70-79 C

60-69 D

Below 60 F

Validation Loops:

In the main menu validation loops must be implemented to validate each of the three test scores which are entered. As long as the test score is less than zero or greater than 100 an appropriate error message should be displayed and the user should be prompted to enter a valid test score. Do NOT implement a decision structure.

General Requirements:

• Variable names MUST follow the naming rules (see page 43), be descriptive, and follow a standard naming convention, such as the textbook naming convention where multiple words are separated by underscores, commonly used by Python programmers (i.e, gross_pay) or camelCase convention (i.e., grossPay).
• Comment statements MUST be included for each major section of code to provide a brief description of its purpose. For example, at the beginning of the input statements, at the beginning of a repetition structure, at the beginning of calculations, or output statements, etc. Single-line comments are adequate.

Sample Scenario:

Enter test score 1: -1
Invalid entry. Test score must be between 0 and 100.
Reenter test score 1: 101
Invalid entry. Test score must be between 0 and 100.
Reenter test score 1: 100
Enter test score 2: -5
Invalid entry. Test score must be between 0 and 100.
Reenter test score 2: 105
Invalid entry. Test score must be between 0 and 100.
Reenter test score 2: 0
Enter test score 3: -10
Invalid entry. Test score must be between 0 and 100.
Reenter test score 3: 110
Invalid entry. Test score must be between 0 and 100.
Reenter test score 3: 50
The test score average is: 50
The letter grade is: F
Do you want to enter test scores for another student (Enter y for yes): y
Enter test score 1: 100
Enter test score 2: 85
Enter test score 3: 90
The test score average is: 91
The letter grade is: A
Do you want to enter test scores for another student (Enter y for yes): y
Enter test score 1: 85
Enter test score 2: 80
Enter test score 3: 89
The test score average is: 84
The letter grade is: B
Do you want to enter test scores for another student (Enter y for yes): y
Enter test score 1: 75
Enter test score 2: 70
Enter test score 3: 80
The test score average is: 75
The letter grade is: C
Do you want to enter test scores for another student (Enter y for yes): y
Enter test score 1: 60
Enter test score 2: 65
Enter test score 3: 60
The test score average is: 61
The letter grade is: D
Do you want to enter test scores for another student (Enter y for yes): n

I’m stuck on a Java question and need an explanation.

5-8. Modify exercise 2-4 where miles per gallon where calculated from the console window. Now modify the program so dialog boxes are used (use all arguments). The prompt and input will be a dialog box instead of a System.out.print() and sc.nextDouble(). The output will be a dialog box instead of a System.out.println(). The input and output will all be the same, but now in dialog boxes. Save as ex58.java and submit it.

 * Exercise 2-4
 * This program will calculate miles per gallon
 * */
import java.util.Scanner;
public class ex24
{
  public static void main(String[] args)
  {
    double miles, gallons, mpg;				// declare variables
    Scanner sc = new Scanner(System.in);

    System.out.print("Enter miles:  ");		// prompt
    miles = sc.nextDouble();				// input
    System.out.print("Enter gallons:  ");
    gallons = sc.nextDouble();

    mpg = miles / gallons;					// calculate

    System.out.printf("Miles per gallon is %.1fn", mpg);  // output
  }
}

Programming Assignment #2: simulation of a database .
Upload program and execution as 2 separate files in canvas
1. Build a list of lists called emp, using the data in file empInsert, shown in canvas files. For
reference, I use the words “table”, “row”, and “column” , for the”2 dimensional” list emp.
For reference, I use the following names (or similar names) for columns: employee_number,
employee name, job, supervisor, hiredate, salary, commission, department numbers (those
names of columns are not necessarily used in the Python program . For example, row number
one will have the following data: 8369, ‘THOMAS’, ‘SECRETARY’, 8902, ’17-DEC-1990′, 1400, null,
20. To build the table emp in the Python program, copy and paste one row at a time from the
file empInsert into the table emp (again, “table” is not a standard Python keyword, I use it to
represent a list of lists or 2-dimensional list). Assumption about the data: names of employees
are unique, employee numbers are unique
2. Print table emp, showing one row per line
3. Print names of employees in alphabetical order
4. Compute and print the incomes for Richard, Mary , and Sean (income is sum of salary, 6th
column and commission, 7th columnIn this assignment, null will be a variable set to 0
5. Build a list of three columns: job (column 3 in emp), total salary for employees with all
employees with this job this job (ignore commission), and avreage salary for this job. Print
in table form
6. The first column of emp is the employee number. The 4th column is the employee number
of the employee’s supervisor. For example, row 1, Thomas has for supervisor Sean
(employee number 8902). Build a list of all employees and their supervisor (2 columns,
employee name, supervisor name)). Print in alphabetical order on employeee name
7. Extra-credit: Build the table dept from the data in file deptInsert (in canvas). Print it (one
row per line). The department number of the table emp (last column) refers to the
department number of first column in dept. For example THOMAS works in department
number 20, which is the RESEARCH department, as showm in table dept. Build a table of
two columns. Column 1 : employee name . Column 2: department name. Print the table,
oe row per line
Whenever possible, program statements must not be based on data you can look at in the two
tables, but based on legitimate computations.
Make the output easy to read, but do not complicate the program with fancy output. Do not
validate the data.
There is no input statements in this program. The data are directly copied into the lists emp
and dept from data in in files empInsert and deptInsert

I’m working on a linux question and need an explanation and answer to help me learn.

1. Scenario: You are working on a web design team, and the site you are building will be hosted on a Linux server. The team is in a design phase where they need a few pieces of placeholder content – images of various sizes that they can use to test their web page layouts before they create the real images. You’re a big Bill Murray fan, mostly because of his earlier work like Caddyshack, but you respect his later, quirkier roles in movies like The Life Aquatic with Steve Zissou and Coffee and Cigarettes. Anyway. Your task is to grab and organize a few large and a few small placeholder images from the website fillmurray.com using only the Linux command-line (and your web browser, for research and testing purposes.)
   1. Create a directory for your project called placeholders
   2. Get 3 small and 3 large images.
   3. Rename them so that the names are informative, i.e., the file names and extensions make sense just from reading the directory contents.
   4. Organize the two sizes into two separate sub-directories of placeholders.
   5. From the placeholders directory, use ls -lR to display the contents of the directory and the contents of its subdirectories.
   6. Submit a screenshot of your terminal showing the output of the ls -lR command.
