ITERATION AND LIST PROJECT

🎯 Learning Focus:

Use iteration (for/while loops) and 1D lists to manipulate and process data.

📝 Task Overview

Scenario:

You're helping a school analyze test scores stored in a 1D list. Your job is to write a program that performs different types of analysis.

🧩 Differentiated Task Levels:

✅ Beginner: Total and Average Calculator

Task:
Given a list of test scores, use a for loop to:

• Print each score
  
  

• Calculate and print the total score
  
  

• Calculate and print the average score
  
  

Example Input:

python

CopyEdit

scores = [85, 90, 78, 92, 88]

Expected Output:

makefile

CopyEdit

Score: 85

Score: 

Average: 86.6

✅ Intermediate: Find High and Low Scores

Task:
In addition to the beginner task, use iteration to:

• Find the highest and lowest scores in the list
  
  

• Count how many scores are above 90
  
  

Hint: Use variables to track max/min and a counter for scores > 90.

✅ Advanced: Custom Statistics and Grading

Task:
Write a program that:

1. Accepts user input for scores (until -1 is entered)
   
   

2. Stores them in a list
   
   

3. Calculates:
   
   

   • Total, average
     
     

   • Highest and lowest scores
     
     

   • Count of scores in grade bands (A: 90+, B: 80–89, C: 70–79, etc.)
     
     

4. Outputs a summary report
   
   

Example Output:

yaml

CopyEdit

Number of Scores: 6

Average: 82.3

Highest: 95

Lowest: 67

Grade Counts: A: 2, B: 2, C: 1, D/F: 1

🛠️ Extension Ideas (Optional)

• Sort the list before displaying results
  
  

• Allow the user to remove or update a score
  
  

• Visualize score distribution using a simple text-based bar chart (e.g., * symbols)
