# This code defines the simulation environment, the resources (rooms and teachers), the courses and majors, and the student 
# process. The choose_courses() method of the Student class is left as a placeholder for you to implement your custom 
# function that determines which courses the student chooses each semester. The attend_courses() method of the Student 
# class requests a room and a teacher for each chosen course and simulates attending the course. The main simulation 
# process run_simulation() creates the students and simulates for 8 semesters, each lasting 16 weeks.

# We initialize Pygame and create a display window to visualize the simulation. In the Pygame loop, we update 
# the display with the simulation elements. You can use Pygame's drawing functions (e.g., pygame.draw.circle(), 
# pygame.draw.rect()) to draw the simulation elements on the screen.
#
# To make the visualization more interactive, you could also add user input (e.g., mouse clicks, keyboard input) to 
# modify the simulation parameters in real time. For example, you could add a button that toggles the display of 
# certain simulation elements or changes the number of students in the simulation.
