Question

IN PYTHON
Write a function that does not receive parameters but the user must enter numbers until they give him a 0. While the user does not give him a 0, the program must show how many numbers were entered, the sum of these numbers and the average (not counting the 0)

example:

16
4
42
8
23
15
0

output:

numbres = 6
sum = 108
average = 18.0

Answer 1

Please find the code below:

def listenInput():
  
count = 0;
total = 0;
while True:
num = int(input())
if(num==0):
break;
else:
count+=1;
total +=num
  
print("Numbers = ",count)
print("Sum = ",total)
print("Average = ",total/count);
  
if __name__ == '__main__':
listenInput()
  
  
  

output:

Answer 2

You can achieve this in Python by creating a function that takes user input in a loop until the user enters 0. Within the loop, you can keep track of the count, sum, and then calculate the average at the end. Here's a Python function that does that:

pythonCopy codedef calculate_stats():
    count = 0
    total_sum = 0

    while True:
        num = int(input("Enter a number (or 0 to stop): "))        
        if num == 0:            break
        
        count += 1
        total_sum += num    if count == 0:        print("No numbers were entered.")    else:
        average = total_sum / count        print(f"Numbers = {count}")        print(f"Sum = {total_sum}")        print(f"Average = {average:.1f}")

calculate_stats()

When you run this function, it will keep asking the user to enter numbers until they input 0. After the user enters 0, it will display the total count of numbers entered, their sum, and the average (excluding the 0). Using the example you provided, the output will be:

vbnetCopy code
Enter a number (or 0 to stop): 16Enter a number (or 0 to stop): 4Enter a number (or 0 to stop): 42Enter a number (or 0 to stop): 8Enter a number (or 0 to stop): 23Enter a number (or 0 to stop): 15Enter a number (or 0 to stop): 0Numbers = 6Sum = 108Average = 18.0
