For Python 3.8+, use statistics.fmean for numerical stability with floats. (Fast.)
For Python 3.4+, use statistics.mean for numerical stability with floats. (Slower.)
xs = [15, 18, 2, 36, 12, 78, 5, 6, 9]
import statistics
statistics.mean(xs) # = 20.11111111111111
For older versions of Python 3, use
sum(xs) / len(xs)
For Python 2, convert len to a float to get float division:
sum(xs) / float(len(xs))

June 15, 2023 -
with inputs 10 and 5, my avg outcome is giving me 8. any help # Initialize the total count variable to 0
total_books = 0
Prompt the user for the first input
book_count = input("Enter the number of books read (or 0 to stop): ")
Continue the loop until the sentinel value "0" is entered
while book_count != "0": # Convert the input to an integer and add it to the total count total_books += int(book_count)
# Prompt the user for the next input
book_count = input("Enter the number of books read (or 0 to stop): ")Display the total number of books read
print("The total number of books read is:", total_books)
Creating the average using total_books
n = total_books total_numbers = n sum = 0 while n >= 0: sum += n n -= 1
average = sum / total_numbers print(("Average = %f") % average)
*outcome
Enter the number of books read (or 0 to stop): 10
Enter the number of books read (or 0 to stop): 5 Enter the number of books read (or 0 to stop): 0 The total number of books read is: 15 Average = 8.000000
Top answer 1 of 5
3
n = total_books total_numbers = n sum = 0 while n >= 0: sum += n n -= 1 Maybe you can walk us through your logic, here.

Your sum is adding all the numbers from the total to 0... That's not what an average should do, you should add the different book readings, then divide it by number of entries.
