Here is a Python program that fulfills the requirements: `python Initialize an empty list to store student scores scores = [] num_students = 20 print(f"Please enter num_students student scores.") Step 1: Input 20 student scores for i in range(num_students): while True: try: score = int(input(f"Enter score for student i + 1: ")) if 0 <= score <= 100: Assuming scores are between 0 and 100 scores.append(score) break else: print("Score must be between 0 and 100. Please try again.") except ValueError: print("Invalid input. Please enter an integer score.") Step 2: Calculate Total, Average, Highest score, Lowest score Check if scores list is not empty to avoid errors if scores: total_score = sum(scores) average_score = total_score / len(scores) highest_score = max(scores) lowest_score = min(scores) else: total_score = 0 average_score = 0 highest_score = "N/A" lowest_score = "N/A" Step 3: Display the results print("--- Student Score Analysis ---") print(f"Total number of students: num_students") print(f"All entered scores: scores") print(f"Total score: total_score") print(f"Average score: average_score:.2f") Format to 2 decimal places print(f"Highest score: highest_score") print(f"Lowest score: lowest_score") ` Explanation: 1. Initialization: An empty list scores is created to store the input scores, and num_students is set to 20. 2. Input Loop: A for loop iterates num_students times. Inside the loop, input() prompts the user to enter each student's score. A while True loop with a try-except block handles potential ValueError if the user enters non-integer input and ensures scores are within a valid range (0-100). Valid scores are appended to the scores list. 3. Calculations: sum(scores) calculates the total score*. len(scores) gets the number of scores, which is used to calculate the average score*. max(scores) finds the highest score*. min(scores) finds the lowest score*. An if scores: check prevents errors if no scores were entered (though the loop ensures 20 scores are entered). 4. Display Results: The calculated total, average, highest, and lowest scores are printed to the console using f-strings for clear formatting. The average score is formatted to two decimal places.
