Python Program to Calculate Sum/Avg of a Given Input

count = 0 #amount of numbers inputted
vSum = 0.0 #variable to track sum
average = 0.0 #variable to track average

data = input('Enter a number or press enter to quit:')
while data != '': #while data is actively being inputted it calculates the sum and count total
    number = float(data)
    count += 1
    vSum += number
    data = input('Enter a number or press enter to quit:') 
    average = vSum/count
if data == '': #once the enter key is hit, process stops and prints sum and average
    print('The sum is', vSum)
    print('The average is', average)
