Question

你好我想知道为什么这段代码不会运行，谢谢。

count = 0
finished = False
total = 0
while not finished:
    number = int(input("Enter a number(0 to finish)"))
    if number == 0:
        finished = True
        else:
            total = total + number
            count = count + 1
print("the average is", total/ count)
count = 0

Answer 1

它确实运行，我能看到的唯一问题是你的else在if块中缩进。在Python中，缩进很重要，因为卷曲括号或关键字在其他编程语言中很重要。

count = 0
finished = False
total = 0
while not finished:
    number = int(input("Enter a number(0 to finish)"))
    if number == 0:
        finished = True
    else:
        total = total + number
        count = count + 1
print("the average is", total/ count)
count = 0

Answer 2

你的脚本没问题，你没有正确缩进else条款，这里有一个工作的例子，你也应该施展你的平均值：

count = 0
finished = False
total = 0

while not finished:
    number = int(input("Enter a number(0 to finish)"))
    if number == 0:
        finished = True
    else:
        total = total + number
        count = count + 1

print("the average is", float(total) / float(count))
count = 0

用几行来做同样的另一种可能的方法是：

values = []
while True:
    number = int(input("Enter a number(0 to finish)"))
    if number == 0:
        break

    values.append(number)

print("the average is", float(sum(values)) / float(len(values)))

Python代码不会运行？
