Python This is the exercise:

1. Course information

Write a 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 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 courses room number, instructor, and meeting time.

THIS IS MY CODE:

# This program is to let the user to search a course number, and display the # courses room number, instructor, and meeting time.

def main( ): # Create a dictionary for the course information course = course_info( )

# Look up the course number that user enter lookup_num(course)

# To create a dictionary for the course information def course_info( ): course = { 'CS101':[3004,Haynes,'8am'], 'CS102': [4501,Alvarado,'9am'], 'CS103': [6755,Rich,'10am'], 'NT110': [1244,Burke,'11am'], 'CM241': [1411,Lee,'1pm'] }

# Return the course return course

# The lookup_num function looks up a course number in the dictionary def lookup_num(course): # Get a number to look up. course_num = input(' Please enter a course number, and the result going to display your course room number, the instructor, and meeting time.') # Look it up in the dictionary. print( course.get( course_num, 'Not found.')) # Call the main function. main( )

Can someone fix the error for me PLEASE!!!!
