9.2.3. Course Info

Instructions

Write a function named get_course_data that creates and returns a nested dictionary containing the course information shown in Table 9.5. The outer dictionary should have a key for each course number. The values associated with each course number in the outer dictionary should be an inner dictionary with the keys: room, instructor, and time, and with values as listed in the table.

Table 9.5 Fake course data.

Number	Room	Instructor	Time
CS101	1461	Django	9:00 a.m.
CS102	4815	Idle	11:00 a.m.
AB203	3634	Rich	10:00 a.m.
NT110	1188	Marshal	2:00 p.m.
CM241	2451	Pickle	12:00 p.m.

Next write the program’s main function so that it lets the user enter a course number, and then displays that course’s instructor, room number, and meeting time. If the course number entered is not in the dictionary, the program should report it as an invalid course number.

Sample Output

Use the values in Table 9.6 below to test your program.

Table 9.6 Test Cases

Case	Course
1	CS102
2	CS201

Ensure your program’s output matches the provided samples exactly. This includes all characters, white space, and punctuation. In the samples, user input is highlighted like this for clarity, but your program should not highlight user input in this way.

Case 1 Sample Output

$ python3 course_info_login.py Enter a course number: CS102 The details for course CS102 are: Instructor: Idle Room: 4815 Time: 11:00 a.m.

Case 2 Sample Output

$ python3 course_info_login.py Enter a course number: CS201 CS201 is an invalid course number.

Deliverables

Save your finished program as course_info_login.py, replacing login with your Purdue login. Then submit it along with all the deliverables listed in Table 9.7 below.
