计算平均值(Calculating averages)

 我一直在努力计算2个不同列表中的平均值。 这是我一直在做的（作为python中的新手）：  
Averagelist = []
Listofvalues1 = ['1', '2', '3', '4']
Listofvalues2 = ['5', '6', '7', '8']

for i, x in enumerate(Listofvalues1):
    for j, y in enumerate(Listofvalues2):
        if j == i:
            AVGvalue = (int(x)+int(y)/2)
            Averagelist.append(AVGvalue)
 
 我自己想出这种方式。 它可能没用，但到目前为止我可以打印我想要用于计算的两个值，但是我得到一个错误“ValueError：int（（）的无效文字，基数为10：'somevalue'”。 这可能是''标志吗？  
 干杯! 

I've struggled with calculating average for values in 2 different lists. Here is what I have been doing (as newbie in python): 
Averagelist = []
Listofvalues1 = ['1', '2', '3', '4']
Listofvalues2 = ['5', '6', '7', '8']

for i, x in enumerate(Listofvalues1):
    for j, y in enumerate(Listofvalues2):
        if j == i:
            AVGvalue = (int(x)+int(y)/2)
            Averagelist.append(AVGvalue)
 
I've come up with this way by myself. It might be useless, but so far I can print both values that I want to use for calculation but I get an error "ValueError: invalid literal for int() with base 10: 'somevalue'". Could it be the '' sign? 
Cheers!

 您可以使用属性等于选择器[name =“value”]  
var td = $('td[art_id="4949"]');
 
 如果变量中有art_id="4949" ，  
var art_id="4949";
var td = $('td[art_id="' + art_id +'"]');
 
 然后单击元素，您可以使用get(index)检索底层DOM元素，然后触发本机click()  
td.get(0).click();
 
 注意：我建议使用data-*前缀自定义属性来存储元素的任意数据。 

You can use Attribute Equals Selector [name=”value”] 
var td = $('td[art_id="4949"]');
 
If have art_id="4949" in a variable, 
var art_id="4949";
var td = $('td[art_id="' + art_id +'"]');
 
Then to click element, you can use get(index) to retrieve the underlying DOM element then to trigger native click() 
td.get(0).click();
 
Note: I would recommend to use data-* prefixed custom attribute to store arbitrary data with the element.
