Question

Using Python. Please help!

The output should looks like below. Please follow the emphasis.

Write a modular program that creates a dictionary containing course numbers and the room numbers of the rooms where the courses meet. The dictionary should have the following key- value pairs: Course Number (key) Room Number (value) CS101 3004 CS102 4501 CS103 6755 NT110 1244 CM241 1411 The program should also create a dictionary containing course numbers and the names of the instructors that teach each course. The dictionary should have the following key-value pairs: Course Number (key) Instructor (value) CS101 Haynes CS102 Alvarado CS103 Rich NT110 Burke CM241 The program should also create a dictionary containing course numbers and the meeting times of each course. The dictionary should have the following key-value pairs: Course Number (key) Meeting Time (value) CS101 8:00 a.m. CS102 9:00 a.m. CS103 10:00 a.m. NT110 11:00 a.m. CM241 1:00 p.m. The program should provide the user with the menu option to perform tasks such as view course details, add class, remove class, view schedule as well as allow the user to determine when to quit. Implement the schedule as nested dictionaries to compile user selected courses and the corresponding course info. User should be able to add up to 4 of the available courses to the schedule. View schedule should display all courses selected by the user with the corresponding course information i.e. course number, room, instructor, & meeting time. Lee

I think it just prompt user to input course name.

Thanks for the question, here is the complete implementation of the code. Let me know if anything else needs to be incorporated

the program is modularised and written with meaningful name so that you can follow.

        print('{0:<10}{1:>20}{2:>20}{3:>20}'.format(course,instructor_dict.get(course),room_dict.get(course),time_dict.get(course)))
