Python示例：计算 10 个数字的和，直到用户输入正数

Python 示例

编写一个 Python示例来寻找 10 个数字的和，直到用户输入正数。在这个 Python 示例中，for 循环允许用户输入 10 个数字，if 条件检查负数。一旦用户输入负值，条件将返回 true，break 语句将退出循环。

Sum = 0

print("Please Enter 10 Numbers\n")
for i in range(1, 11):
    num = int(input("Number %d = " %i))

    if num < 0:
        break

    Sum = Sum + num

print("The Sum of Positive Numbers = ", Sum)

这个 Python示例找到 10 个数字的和，直到用户使用 while 循环输入正数。

Sum = 0

print("Please Enter 10 Numbers\n")
i = 1
while(i <= 10):
    num = int(input("Number %d = " %i))

    if num < 0:
        break

    Sum = Sum + num
    i = i + 1

print("The Sum of Positive Numbers = ", Sum)

Please Enter 10 Numbers

Number 1 = 23
Number 2 = 90
Number 3 = 98
Number 4 = 56
Number 5 = 47
Number 6 = -90
The Sum of Positive Numbers =  314
