The average of the sequence. Determine the average of all elements in a sequence of non-negative integers, where the sequence ends with the number 0. Do not include the 0 in the calculation of the average.

Explanation of the Code
- Initialize Sum and Count:
- Initialize two variables,
total_sum and count, to 0. These will keep track of the sum of the integers and the count of the integers in the sequence, respectively.
- Reading Input and Summing:
while True:
num = int(input())
if num == 0:
break
total_sum += num
count += 1
- Use a
while True loop to continuously read input.
- Convert the input to an integer using
int().
- If the integer is 0, break the loop.
- If the integer is not 0, add it to
total_sum and increment count by 1.
- Calculating and Printing the Average:
if count > 0:
average = total_sum / count
print(average)
- If
count is greater than 0, calculate the average by dividing total_sum by count.
- Print the calculated average.
