Firstly, input an integer � N, which represents a total of � N students. Then enter � N lines, each containing the student's name, class, exam 1 score, and exam 2 score. Count the average and total scores of each exam for each class, and sort the results by class name before outputting them to the console. Output includes class, score1_mean, score1_sum, score2_mean, score2_sum.

Sure, I can help you with that. Here's an example Python code that solves the problem you stated:

# Input the total number of students
N = int(input())

# Create a dictionary to store the results for each class
class_results = {}

# Loop through each student and store their results in the dictionary
for i in range(N):
    name, class_name, exam1, exam2 = input().split()
    exam1 = int(exam1)
    exam2 = int(exam2)
    if class_name not in class_results:
        class_results[class_name] = {'exam1_total': 0, 'exam1_count': 0, 'exam2_total': 0, 'exam2_count': 0}
    class_results[class_name]['exam1_total'] += exam1
    class_results[class_name]['exam1_count'] += 1
    class_results[class_name]['exam2_total'] += exam2
    class_results[class_name]['exam2_count'] += 1

# Sort the results by class name
class_names = sorted(class_results.keys())

# Print the results for each class
for class_name in class_names:
    exam1_mean = class_results[class_name]['exam1_total'] / class_results[class_name]['exam1_count']
    exam2_mean = class_results[class_name]['exam2_total'] / class_results[class_name]['exam2_count']
    exam1_sum = class_results[class_name]['exam1_total']
    exam2_sum = class_results[class_name]['exam2_total']
    print(f"{class_name} {exam1_mean:.2f} {exam1_sum} {exam2_mean:.2f} {exam2_sum}")

Here's how you can use this code:

1. Copy and paste the code into a Python file (e.g. `main.py`).
2. Run the Python file using the command `python main.py`.
3. Enter the total number of students when prompted.
4. Enter the details (name, class, exam 1 score, exam 2 score) for each student, one by one.
5. The program will print the results for each class, sorted by class name.

I hope this helps! Let me know if you have any questions.
