Creating a separate Counter() object and Pandas DataFrame for each list within a list of lists

白昼怎懂夜的黑 提交于 2019-12-02 14:23:33
问题 All the other answers I could find specifically referred to aggregating across all of the nested lists within a list of lists, where as I'm looking to aggregate separately for each list. I currently have a list of lists: master_list = [[a,a,b,b,b,c,c,c], [d,d,d,a,a,a,c,c,c], [c,c,c,a,a,f,f,f]] I want to return a dictionary or Counter() objects for each list with a loop: counter1 = {'a': 2, 'b': 3, 'c': 3} counter2 = {'d': 3, 'a': 3, 'c': 3} counter3 = {'c': 3, 'a': 2, 'f': 3} Currently, I'm

have to create a matlab counter [duplicate]

无人久伴 提交于 2019-12-02 13:41:10
This question already has an answer here: Create a “counter” on matlab from 0:limit-1. The length of counter is not determined in the program 1 answer Q- Create a "counter" from 0:limit-1 (for example if you choose 3 it will display 0,1,2). The length of counter is not determined in the program and it should be determined when it is being run and the inputs can differ from each other not really sure what you mean...but for i = 0:limit-1 disp(i) end will display 0,1,2 ... limit-1 来源: https://stackoverflow.com/questions/16477924/have-to-create-a-matlab-counter

VHDL Counter Error (vcom-1576)

Counting changes in an array

☆樱花仙子☆ 提交于 2019-12-02 13:30:22
I would like to count the number of times "red" is followed by "green" in this array: ["red", "orange", "green", "red", "yellow", "blue", "green"] If it is another color, the code should ignore it and proceed to the next item in the array. event_type.each_slice(2) do |red, green| break unless green count = count + 1 end p "The count is #{count}" Step 1: Look for red Step 2: IF not last item Compare with next item on array ELSE Go to Step 4 Step 3: IF green, count = count + 1 Go to Step 1 ELSE Go to Step 2 Step 4: Print Count Below one is solution I believe. Sure there is more room to refactor

Please help me to get the counter for the list SS2 in list SS1 in PYTHON using from collections import Counter or any other fastest way SS1 = [(1, 2, 3, 4, 5), (1, 2, 3, 4, 6), (1, 2, 3, 5, 6), (1, 2, 4, 5, 6), (1, 3, 4, 5, 6), (2, 3, 4, 5, 6)] SS2=[(1, 2, 3), (1, 2, 4), (1, 2, 5), (1, 2, 6), (1, 3, 4), (1, 3, 5), (1, 3, 6), (1, 4, 5), (1, 4, 6), (1, 5, 6), (2, 3, 4), (2, 3, 5), (2, 3, 6), (2, 4, 5), (2, 4, 6), (2, 5, 6), (3, 4, 5), (3, 4, 6), (3, 5, 6), (4, 5, 6)] Here is what i have tried and i don't know how to get the count for (1,2,4) th elements of the each tuple SS1=[(1, 2, 3, 4, 5), (1

a to the power of b without (a**b), Python

时间秒杀一切 提交于 2019-12-02 12:23:42
Struggling with an exercise that asks me to write a**b without this operator. Tried to write something myself but am not getting correct results. Instead of one value am getting two, both incorrect. Seems like the counter doesnt really increase. May I ask for help? Thanks! def powerof(base,exp): result=1 counter=0 # until counter reaches exponent, go on if counter<=exp: # result multiplies itself by base, starting at 1 result=result*base # increase counter counter=counter+1 return result return counter # here it says "unreachable code". Can I not return more variables at the same time? else: #

Implementation of custom counter logic in SIMULINK

六月ゝ 毕业季﹏ 提交于 2019-12-02 11:14:26
I am trying to implement a counter logic in SIMULINK where in1, in2 are inputs out1 is the output if in2 = 0, out1 = 0; if in2 = 1, out1 = 1 after x high edges of in1 I have tried using "Detect Rise Positive" block but failed miserably because I don't have sufficient experience of implementing a timing diagram correctly in SIMULINK. Could anyone kindly point me to the right direction? Update An approach I have taken since I posted this question is the "Triggered and enabled subsystem". I am trying to set it up so that: in2 becomes the enable signal in1 becomes the trigger in2 becomes the

1.v-on事件 <div id="example-1"> <button v-on:click="counter += 1">Add 1</button> <p>The button above has been clicked {{ counter }} times.</p> </div> var example1 = new Vue({ el: '#example-1', data: { counter: 0 } }) 结果: 你每点击一下按钮counter就会自动加1 2.事件处理方法 然而许多事件处理逻辑会更为复杂,所以直接把 JavaScript 代码写在 v-on 指令中是不可行的。因此 v-on 还可以接收一个需要调用的方法名称 示例: <div id="example-2"> <!-- `greet` 是在下面定义的方法名 --> <button v-on:click="greet">Greet</button> </div> var example2 = new Vue({ el: '#example-2', data: { name: 'Vue.js' }, // 在 `methods` 对象中定义方法 methods: { greet: function (event) { // `this` 在方法里指向当前 Vue 实例 alert('Hello ' +

Unable to set incremental variable in Jmeter

拥有回忆 提交于 2019-12-02 10:17:58
Here is my simple Jmeter test plan. User Parameters look like this: I'm simply calling one endpoint, reading the response body and according to found IDs with the help of Regex Extractor I'm calling another endpoint. ForEach loop helps make sure for all the found IDs same endpoint is called with ID as parameter in the Path. What I'm trying to achieve with Another HTTP Request inside ForEach loop is to read the response, and if body contains Monday , increment User Parameter Monday by 1, same for Tuesday and for every other User Parameter . Ideally at the end of the test suite, I should get

Session counter with HttpSessionListener and session count variable access

北战南征 提交于 2019-12-02 09:39:07
I saw an example with session counter in Sun's "Core Servlets and JavaServer Pages vol 2". Counter is simply build on HttpSessionListener and increments/decrements session count with sessionCreated / sessionDestroyed : public class SessionCounter implements HttpSessionListener { private int currentSessionCount = 0; public void sessionCreated(HttpSessionEvent event) { currentSessionCount++; } ... public int getTotalSessionCount() { return(totalSessionCount); } ... // counter decrement, self registering in context attribute etc. Listener register itself in context, so servlets can access it and
