![# Lab 9 – Dictionaries
## 1. Course Information
Write a program that creates a dictionary containing course numbers and the room numbers 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 | Lee
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 let the user enter a course number, then it should display the course’s room number, instructor, and meeting time.
If the course is not in the dictionary, a message should be displayed. The program should contain a loop which continues to ask for a course number until the user chooses to quit.
### Sample Dialog:
```
Enter a course number or press enter to stop: absdfs
absdfs is an invalid course number.
Enter a course number or press enter to stop: CS101
The details for course CS101 are:
Room: 3004
Instructor: Haynes
Time: 8:00 am
Enter a course number or press enter to stop:
>>>
```
Your programs should conform to the Programming Style Requirements as listed in Blackboard under Lab Assignments. You should have 1 .py file to turn in.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcde25e33-7fc7-4235-919c-031120b86f94%2F3224abbf-7ada-4402-a901-0fbc9d10938f%2Fqvwisk8_processed.png&w=3840&q=75)
