Find average of list elements Program Code

# Find average of list elements
marks = [78, 85, 92, 88, 76, 95, 89]
print("Marks:", marks)

# Calculate average = sum / count
total = 0
for mark in marks:
    total += mark

average = total / len(marks)
print(f"Sum = {total}")
print(f"Count = {len(marks)}")
print(f"Average = {average:.2f}")

# Using built-in functions
avg = sum(marks) / len(marks)
print(f"Using built-ins: {avg:.2f}")
