Student Directory

Unit 2 Session A

U-nderstand

Understand what the interviewer is asking for by using test cases and questions about the problem.

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Create a dictionary from a list of keys (student names) and generate a unique ID for each value.

1) Create a new, empty dict
2) The current student ID starts at 1
3) For each student name:
  a) In the new dict, map name -> current ID
  b) Increment current ID by one
4) Return the new dict

I-mplement

def student_directory(student_names):
    student_dict = {}
    student_id = 1  # Start student IDs at 1
    for name in student_names:
        student_dict[name] = student_id
        student_id += 1
    return student_dict
