• Difference between input
We all know input markup in XHTML, which can be used to create TextBox, Button, CheckBox, RadioButton, HiddenField etc via type attribute. There are three types of button, one is used to submit form, another is used to reset form, the third one has no default actions, which should be enhanced by JavaScript.There is another markup usded to present a button is button, following is found in the W3C site:Buttons created with the BUTTON element function just li

Key: we need to use SET function. def average(array): sum1=sum(set(array)) n=len(set(array)) return(sum1/n) [caption id=&quot;attachment_2136&quot; align=&quot;alignnone&quot; width=&quot;650&quot;] 12019 / Pixabay[/caption] 2.

• 每天一个lodash方法（7）
Array method 系列之七 —— intersectionintersection和difference是功能相反的两个方法。difference是抛出数组中相同的部分，留下不同的部分，即取补集。而intersection是留下相同的部分，即取交集。intersection系列包含三个方法：intersection、intersectionBy、intersectionWith。和difference系列相似，intersection提供多个数组的基础比较取交集。intersectionBy利用iteratee方法对数组元素进行预先处理。intersectionWith利用comparator比较器自定义比较方法。但是三种方法的思路很相似。对参数进行预处理。得到array，comparator，iteratee。执行baseIntersection方法根据数组长度判断是否缓存。缓存源码此处略过。双重遍历：判断第一个数组的每个元素是否包含在其余数组中。结果返回。以下是源码。//&nbsp;inters
