修改下面代码中的错误，不可添加或删减一行代码

def add_pos([vals]):
total = 0
for num in range(vals):
if vals > 0:
total = total + num
return total

count = 0
data = list
while count < 8:
num = int(input("Enter a number: "))
data = data.append(num)
count + 1
print("The total is", add_pos([]))

        if num > 0:
            total = total + num
    return total

count = 0
data = list()
while count < 8:
    num = int(input("Enter a number: "))
