Write a Python program stored in a file q1.py that: Asks the user to get the code of a subject as input. The code consists of 4 characters separated by a space followed by a 3 digit number. We have computer science (CSCE), mechanical (MEEN), visualization(VIZA), mathematics(MATH) and statistics(STAT) departments. If the given code does not belong to any of the above-mentioned departments, the program should keep running until the user enters the correct answer.

Write a method that takes in an array of point2d objects, and then analyzes the dataset to find points that are close together. be sure to review the point2d api. in your method, if the distance between any pair of points is less than 10, display the distance and the (x,y)s of each point. for example, "the distance between (3,5) and (8,9) is 6.40312." the complete api for the point2d adt may be viewed at ~pf/sedgewick-wayne/algs4/documentation/point2d.html (links to an external site.)links to an external site.. try to write your program directly from the api - do not review the adt's source code.
