Write a Python program to calculate and display the total, average, highest, and lowest scores for 20 students.

Here is a Python program that fulfills the requirements: `python Initialize an empty list to store the scores scores = [] num_students = 20 print("Please enter 20 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, and Lowest scores total_score = sum(scores) average_score = total_score / num_students highest_score = max(scores) lowest_score = min(scores) Step 3: Display the results print("--- Student Score Analysis ---") print(f"Total number of students: num_students") 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. scores = []: An empty list named scores is created to store the scores entered by the user. 2. num_students = 20: A variable is set to define the number of scores to be input. 3. Input Loop: A for loop runs num_students (20) times. Inside the loop, input() prompts the user to enter a score for each student. int() converts the input string to an integer. A while True loop with try-except block handles potential ValueError if the user enters non-integer input and ensures scores are within a valid range (0-100). scores.append(score) adds the valid score to the scores list. 4. Calculations: total_score = sum(scores): The built-in sum() function calculates the sum of all scores in the list. average_score = total_score / num_students: The average is calculated by dividing the total score by the number of students. highest_score = max(scores): The built-in max() function finds the largest score in the list. lowest_score = min(scores): The built-in min() function finds the smallest score in the list. 5. Display Results: Finally, print() statements are used to display all the calculated values in a clear format. The average score is formatted to two decimal places using an f-string :.2f.
