Requirements You are to use Python 3 with the python-constraint package to determine the number of possible degree plans for a given start and end term under the constraints given below. Also, your code should generate one possible degree plan that satisfies all constraints. The information needed for formulating the CSP is given within the two sheets of the csp_course_rotations.xlsx file. The first sheet (course_rotations) provides a listing of all available courses, their type (foundation, core, elective, or capstone), and the term availability (0 - unavailable, 1 - available) for each of the terms (1: Fall 1, 2: Fall 2, 3: Spring 1, 4: Spring 2, 5: Summer 1, 6: Summer 2). The second sheet (prereqs) specifies which course must be taken before another. Note that a course may have multiple prerequisites. Your program must output the number of possible degree plans and one possible degree plan for a student that starts in Year 1 Fall 1 and finishes in Year 3 Fall 2. The degree plan must satisfy the following requirements: 1. Student will take one and only one course per term. 2. Course that has prerequisites must be taken in a term that follows the term in which all prerequisites are done. 3. The student does not need to repeat courses. 4. Some terms may be skipped as long as the student finishes in Year 3 Fall 2. 5. Student needs to take 3 out of the 8 elective courses. It doesnt matter which ones are included in the degree plan. Those courses which are not taken will be labeled as Not Taken (see sample output). 6. Student must take all foundation and core courses. The program will generate the output shown in the sample output at the end.

Additional Requirements 1. The name of your source code file should be mp3.py. All your code should be within a single file. 2. You can only import numpy, pandas, and constraint packages. 3. Your code should follow good coding practices, including good use of whitespace and use of both inline and block comments. 4. You need to use meaningful identifier names that conform to standard naming conventions. 5. At the top of each file, you need to put in a block comment with the following information: your name, date, course name, semester, and assignment name. What to Turn In You will turn in the single mp3.py file using BlackBoard. HINT You can load an Excel file using pandas pd.read_excel function. The sheet is specified by the sheet_name attribute. ************************************* Sample Program Output CLASS: Artificial Intelligence, Lewis University NAME: [put your name here] START TERM = Year 1 Fall 1 Number of Possible Degree Plans is 9488 Sample Degree Plan Not Taken CPSC-57400 Not Taken CPSC-57200 Not Taken CPSC-57100 Not Taken CPSC-55200 Not Taken CPSC-51700 Year 1 Fall 1 CPSC-50600 Year 1 Fall 2 MATH-51100 Year 1 Spring 1 MATH-51000 Year 1 Spring 2 MATH-51200 Year 1 Summer 1 CPSC-50100 Year 2 Fall 1 CPSC-51100 Year 2 Fall 2 CPSC-53000 Year 2 Spring 1 CPSC-54000 Year 2 Spring 2 CPSC-55500 Year 2 Summer 1 CPSC-51000 Year 2 Summer 2 CPSC-52500 Year 3 Fall 1 CPSC-55000 Year 3 Fall 2 CPSC-59000
