我需要一些帮助 [英] i need some help

问题描述

我是python语言的初学者，我有以下问题：


i我试图在某些限制下定义一些东西，比方说X，我不知道该怎么做那。


基本上我想做以下事项：如果X小于200且大于100，则继续，否则停止。


可以为某人提供某种起点。我知道我必须做一个for循环，但不确定如何去做。


提前感谢

你不需要for循环。使用 if 语句测试条件。如果满足条件，做一些事情。否则，做一些其他事情。

抱歉，我应该提到整件事，因为我仍然不确定。

我这里的x实际上是一个值列表。我有2个值对应的id列表，我试图使用这两个列表定义参数。我只是不知道正确的符号和编写代码：

i我正在尝试以下但没有成功：


>>> ; x =字段[1] - 我的列表

>>> y = filelds [2] - 第二个列表

>>>如果100< = x< = 200

>>>>>继续

>>>>>>>如果5< = y< = 8

>>>>>>>> print id（打印具有已定义参数的id）


再次感谢您的帮助

您将需要一个for毕竟循环。我认为字段是一个列表列表。也许像下面这样的东西？

I am a beginner in python language and I have the following question:

i am trying to define something, let say X, under certain limits and I am not sure how to do that.

basically i want to do the following: if X is less than 200 and greater than 100, then continue, else stop.

can someone provide some kind of starting point. i know i have to do a for loop, but not exactly sure how to go about it.

thanks in advance

You don''t need a for loop. Test for a condition with an if statement. If condition is met, do something. Otherwise, do something else.

sorry, i should have mentioned the whole thing because I am still unsure.
My x here is actually a list of values. And i have 2 lists of values that correspond to an id and I am trying to define parameters using the two lists. i just don''t know the proper notation and such to write the code:
i am trying the following with no sucess:

>>> x = fields [1] -- my list
>>> y = filelds [2] -- 2nd list
>>> if 100 <= x <= 200
>>>>> continue
>>>>>>> if 5 <= y <= 8
>>>>>>> print id (print the id that has the defined parameters)

Thanks again for any help

You will need a for loop after all. I take it that fields is a list of lists. Maybe something like the following?
