How to count co-ocurrences with collections.Counter() in python?

由 大兔子大兔子 提交于 2019-12-05 02:09:34
问题 I learned about the collections.Counter() class recently and, as it's a neat (and fast??) way to count stuff, I started using it. But I detected a bug on my program recently due to the fact that when I try to update the count with a tuple, it actually treats it as a sequence and updates the count for each item in the tuple instead of counting how many times I inserted that particular tuple . For example, if you run: import collections counter = collections.Counter() counter.update(('user1',

XQuery counters inside a for

由 我只是一个虾纸丫 提交于 2019-12-05 01:38:12
问题 Let's say I have the XQuery code below: for $y in doc("file.xml")/A/B for $x in $y/C where $x/constraint1 != "-" and $x/constraint2 > 2.00 do stuff Can I use a counter, to count how many my code will enter inside the second for loop? I tried this: for $y in doc("file.xml")/A/B let $i := 0 for $x in $y/C where $x/constraint1 != "-" and $x/constraint2 > 2.00 $i := $i + 1 but I got compile errors. I also I need to sum some constraints like this: for $y in doc("file.xml")/A/B let $i := 0 let $sum

JavaScript function to automatically count consecutive letters in a string

由 守給你的承諾、 提交于 2019-12-05 00:59:04
问题 I am attempting (unsuccessfully) to write JavaScript function LetterCount to count the consecutive letters in a string (and not the total number). Ideally: LetterCount("eeeeeoooohhoooee") = [["e", 5],["o",3],["h",2],["o",3],["e",2]] The following code attempts to count the number of consecutive letters in a string only when I already know what they are: function LetterCount(str) { for (var i=0; i<str.length;i++) { var arr1=[]; arr2=[]; arr3=[]; arr4=[]; arr5=[]; var e=0; o=0; h=0; o2=0; e2=0;

How can I make a PHP counter?

由 筅森魡賤 提交于 2019-12-05 00:35:32
问题 I know I have done this in Javascript once, but how can I make it in PHP? Basically I want to do this: if (empty($counter)){ $counter = 1; }else{ "plus one to $counter" ($counter++?) } But it didn't work when I tried. How would I go about doing this? Thank you :) EDIT: This is so I can do: if ($counter == 10){ echo("Counter is 10!"); } EDIT: This is all in a "while()" so that I can count how many times it goes on, because LIMIT will not work for the query I'm currently doing. 回答1: why the

Javascript Remaining Characters without input

由 限于喜欢 提交于 2019-12-04 19:36:57
Is it possible to have a pure Javascript text remaining counter that outputs the value in a <span> or <p> tag rather than an input field? I can only find Jquery solutions or ones that output in input fields. Have seen over the net that a lot of people are wanting a remaining characters counter that is pure Javascript and doesn't preview the number in an input box. I was messing around with JSFiddle lastnight and did a little work around and was able to get the remaining characters to show in other tags such as <span> . So I would just like to share this with everyone and hope it might come in

1.v-if和v-show 　 　 v-if 和v-show都可以显示和隐藏元素； 　区别：（1）v-if初始值为false那么这个元素不会被渲染 ，v-show不管初始值为何值都会被渲染 　　　　（2）v-if是控制DOM元素是否插入，v-show是控制css的display属性 　　　　（3）v-if适合隐藏尚未加载的内容或切换显示与隐藏频率较低的地方，v-show反之; 　　此外还有两个条件语句和v-if有关：v-else-if ,v-else 1 <div v-if="state==='loading'">加载中。。。</div> 2 <div v-else-if="state==='errr'">出错了。。。</div> 3 <div v-else>我的内容</div> 　　当根据state的值显示不同的内容 2.v-for循环 　　直接看示例： <ul> <li v-for="（item，index） in state " :key="item.index">{{item.content}}</li> </ul> 　　该指令可遍历对象也可遍历数组，key为li的唯一标识符，可保证高效渲染，还可以保证标签顺序不会错乱； 3.v-bind属性绑定，简写 “ : ” 　　示例　　　 <button :type="test"></button> 　　该指令可以接收参数

How can I get a weighted random pick from Python's Counter class?

由 ∥☆過路亽．° 提交于 2019-12-04 17:17:46
问题 I have a program where I'm keeping track of the success of various things using collections.Counter — each success of a thing increments the corresponding counter: import collections scoreboard = collections.Counter() if test(thing): scoreboard[thing]+ = 1 Then, for future tests, I want to skew towards things which have generated the most success. Counter.elements() seemed ideal for this, since it returns the elements (in arbitrary order) repeated a number of times equal to the count. So I

How to get the python Counter output ordered by order of inputs?

由 橙三吉。 提交于 2019-12-04 11:19:44
I have been working on getting the count(frequency) and then making the graph representation of it. I am using Counter class from collections using python. I want the output of the Counter in the order of the first come object. for example: offset=['a','b','c','a','b','b','b','c','c','c','c','c'] counts = Counter(offset) print counts output is: Counter({'c': 6, 'b': 4, 'a': 2}) As I want the output to be as follows, in the order of the first come object: Counter({'a': 2, 'b': 4, 'c': 6}) Is that possible?

Track Page Views using PHP

I'm looking for a way to track the number of visits to a page, without counting duplicates (like someone hitting refresh several times) and I'd like to figure out the best way to do it without keeping track of every single IP address to view the page. Perhaps a cookie? Any other suggestions?

Powershell Get a specific process counter with id process

由 白昼怎懂夜的黑 提交于 2019-12-04 08:51:34
I want to get specific counters for processes that I have process id's for. However I can't think of a way to use where-object to match the process for the counter. Like Where Gc '\process(*)\id process -eq 456 gc '\process($name)\working set' So use the process id to retrieve the name and get the working set (or something to that effect). You can get counters for a process name so first get the process name by using its Id and then embed the process name in the counter. For example: $id = # your process id $proc = (Get-Process -Id $id).Name Get-Counter -Counter "\Process($proc)\% Processor
