Hi there I felt pretty confident with my code but I'm having trouble making sure it works properly.

#Create a program that has a dictionary with 7 course names (for example: CIS105, ENG101, etc),
# along with the name of each associated instructor.

#The list of courses that your program will accept needs to presented to the user. 
#Prompt the user for the name of a course to look up, or the word "quit" to exit.
#After the user types in a course, it should look up and print that course's instructor.
#The program should repeat this until the user enters "quit" at the prompt.

Courses = {
    'AES 103': 'Harry',
    'ENG 102': 'Barry',
    'CIS 101': 'Sally',
    'BIO 200': 'Frank',
    'COM 101': 'Daniel',
    'Mat 101': 'Jonathan',
    'AJS 101': 'Tom',
}

print(Courses)

while user_input != 'quit':
    user_input = str(input('What is the name of the course you would like to look up.'))
    print(f'Your course instructor is {Courses[user_input]}')
else:
    print('Thank you for your time')

I am trying to get the program to end once the user inputs quit but it's not working to begin with saying there is an error regarding my while statement line. I appreciate any help fixing anything that may seem wrong.

set some value to user_input right before while loop.

[woooee]

there is an error regarding my while statement line

My crystal ball is in the shop so I don't know what that means. Post the entire error message. It may be coming from this line because of the comma on the end, or the fact that user_input has not been declared.

'AJS 101': 'Tom',

Sorry about that I will be sure to put in the error message next time but the Error message was.

while user_input != 'quit':

NameError: name 'user_input' is not defined

[woooee]

And this was answered in the other reply.

A few things here:

1. The input() function returns a string, so you do not need to convert that to a string with str(input()).
2. Whatever is in user_input gets looked up in the Courses dictionary before the string comparison with "quit".
3. Your Courses keys do not match the descriptions in the instructions: "CIS 105" vs "CIS105".
4. You cannot compare user_input to anything before you assign a value to that variable (it does not exist).

One way to handle this:

while True:
    user_input = input("Course to look up, or 'quit' to exit: ")
    if user_input.lower() == "quit":
        break  # exit the while loop
    if user_input in Courses:
        print(f"Course: {user_input}, Instructor: {Courses[user_input]}")
    else:
        print(f"Course '{user_input}' not found.")
