Study Notes
Parallel Lists Overview
- Parallel lists are used to store related data in separate lists that align with each other based on their index positions.
- Each list contains elements that share a common relationship, allowing for organized data management.
Origin of the Term 'Parallel'
- The term 'parallel' refers to the alignment of the lists; each corresponding index across the lists represents related data points.
- For instance, the first element in one list corresponds directly to the first element in another, maintaining a clear structure.
Example of Parallel Lists
- An example includes a list of student names and a corresponding list of their scores.
- Names: Alice, Bob, Carol
- Scores: 90, 85, 88
- Here, Alice's score (90) is found at the same index (0) as her name in both lists.
Relationships Between Elements
- Elements in parallel lists relate to each other through their index positions; if a list’s item at index 1 represents a student name, the item at index 1 of the score list represents that same student's score.
Benefits of Parallel Lists
- Parallel lists efficiently handle structured data, making it easy to add, modify, or retrieve related items without requiring complex data structures.
- They simplify the code used in programming when accessing related data, enhancing clarity and reducing errors in data management.
