Write a program that receives a series of numbers from the user and allows the user to press the enter key to indicate that he or she is finished providing inputs. After the user presses the enter key, the program should print: The sum of the numbers The average of the numbers

Next, we prompt user to input the first number (Line 4). While the num is not ' ' (This means it is not "Enter" key), accumulate the num to sum variable and increment count by one (Line 6-8) and then prompt the user to input the next number (Line 9).

At the end, display the sum and average using print function (Line 11 -12).

Following are the python code to the given question:

Program Explanation:

Defining "s, n" variable that initializes the value, and defines while loop.
Inside the loop "d" variable is declared that inputs the value by user-end.
Inside this, if block, is defined the check value is empty so, it breaks the condition, and in the "s" variable it adds the input value.
After adding value, "n" is defined that incrementing its value, and use print method is used that prints sum and calculates the average value.

Program:

s = 0.0#defining a double variable that initializes a value 0

n = 0 #defining an integer variable that initializes a value 0

while True:#defining a while loop that adds inputs value

d= input("Enter a number or press Enter to quit: ")#defining d variable that inputs value

if d == '':#defining if block that checks d value equal to empty or space value

break#using break condition

s = s+float(d)#using s variable that adds value

n =n+ 1#defining n variable that incrementing its value

print("The sum is", s)#using print method that prints addition of the value

print('The average is', s / n)#using print method that calculate the average of the value

Output:
