初学Python，按回车结束输入数值，求和与平均值，开始出现问题，后解决

count = 0

total=0
data = int(input("Enter a number or press enter to quit: "))

while data != "":
        count += 1

number = data

total += number

average = total / count

       data =int( input("Enter a number or press enter to quit: "))
  print("The sum is", total, ". ", "The average is", average)

修改为：

count = 0

total=0
data = input("Enter a number or press enter to quit: ")

while data != "":
   data=int(data)
   count += 1

   number = data

   total += number

   average = total / count

   data = input("Enter a number or press enter to quit: ")
  

print("The sum is", total, ". ", "The average is", average)
