我如何使用 while 循环和 Python 进行编码

Question

创建一个程序，将 1、2、3... 中的所有数字相乘，并在乘积大于 1000 时结束。

我尝试了这段代码，但它不起作用。

produkt = 1

while produkt<1000:

    print(produkt)

    produkt = produkt*(produkt +1)

    if produkt < 1000:

        break

Answer 1

produkt = 1counter = 2while produkt < 1000:&nbsp; &nbsp; print(produkt, end=" ")&nbsp; &nbsp; produkt = produkt * counter&nbsp; &nbsp; counter += 1print(produkt)1 2 6 24 120 720 5040

Answer 2

只是为了好玩。>>>&nbsp;next(filter(1000&nbsp;.__lt__,&nbsp;itertools.accumulate(itertools.count(1),&nbsp;operator.mul))) 5040

Answer 3

我想你想要：number = 1produkt = numberwhile produkt<=1000:&nbsp; &nbsp; print(produkt)&nbsp; &nbsp; number += 1&nbsp; &nbsp; produkt = produkt * number结果：12624120720

Answer 4

您需要 2 个变量，一个用于存储，total另一个用于存储index(1, 2, 3, ...)index = 1total = 1while index < 1000:&nbsp; &nbsp; total *= index&nbsp; # same as: total&nbsp; &nbsp; = total * index&nbsp; &nbsp; index += 1&nbsp; # same as: index = index +1&nbsp; &nbsp; # print(f'{index - 1} => {total}') uncomment if you want to follow the valuesprint(f"Stop at total {total}, index was {index}")你会得到以下内容1 => 12 => 23 => 64 => 245 => 1206 => 7207 => 50408 => 403209 => 36288010 => 3628800...Stop at total 402...000, index was 1000

Answer 5

您可以按以下方式修改代码：变量produkt取值 1,2,3,...，它们的乘积存储在produkt_end.produkt = 1produkt_end = 1while True:&nbsp; &nbsp; print(produkt_end)&nbsp; &nbsp; produkt_end = produkt_end*produkt&nbsp; &nbsp; produkt = produkt+1&nbsp; &nbsp; if produkt_end > 1000:&nbsp; &nbsp; &nbsp; &nbsp; break它将显示produkt_end：112624120720
