counter

问题 How can I simply transform this loop to count up from 1 to 100, and display the numbers? I'm starting to code recently. It works fine when counting down, but I can't figure out how to make it go from 1 -100 example: count = 100 while count > 0 : print(count) count = count - 1 回答1: Start at 1, and change your conditional to break out when you reach 100. Add 1 each loop through. count = 1 while count <= 100: print(count) count += 1 回答2: If you use a for loop it gets really easy: for number in

问题 I have two counters stored with sharedpreferences and I need to reset them to zero everyday at midnight, I know I have to use alarmmanager but I don't really know how I have to do it, I looked at SO exemples and on the google documentation but can't find a way to do it. the two counters I have are stored like this: SharedPreferences.Editor editor = counters.edit(); editor.putInt("wcounter", wcounter); editor.commit(); how can I reset them at midnight? 回答1: Set the alarm somewhere appropriate

问题 I'm struggling on how to increment a basic counter in javascript. What do I want to achieve ? I need a counter inside a foreach loop. The goal is to be able to count each time the //Write smthg is triggered. Below is the updated version of the code I'm using. For the moment, it returns weird sequences of numbers. I guess it is resetted each time the recursive loop is triggered. I do not know how to correct it, suppose it's a basic javascript problem but as I'm learning through experimenting

问题 I have a dataframe with sentences and a dictionary of terms grouped into topics, where I want to count the number of term matches for each topic. import pandas as pd terms = {'animals':["fox","deer","eagle"], 'people':['John', 'Rob','Steve'], 'games':['basketball', 'football', 'hockey'] } df=pd.DataFrame({ 'Score': [4,6,2,7,8], 'Foo': ['The quick brown fox was playing basketball today','John and Rob visited the eagles nest, the foxes ran away','Bill smells like a wet dog','Steve threw the

问题 My Professor wants me to this: Write a number of interchangeable counters using the Counter interface below public interface Counter { /** Current value of this counter. */ int value(); /** Increment this counter. */ void up(); /** Decrement this counter. */ void down(); } Develop the following: An interface ResetableCounter that supports the message void reset() in addition to those of Counter. Here's what I did: public interface ResetableCounter { void reset(); int value(); void up(); void

问题 I want to count how much time visitors spend on a certain page and store it in my MySQL DB. I thought of just starting a timer on window.onload like this: window.onload= startCount; window.onunload= sendCount; var b=0; var y; function startCount() { document.getElementById('livecount').innerHTML=b; b=b+1; y=setTimeout("startCount()",1000); } and after the visitor leaves the page (window.onunload), I'm sending the time through an XMLHttpRequest to a PHP file, which will store it in my DB:

问题 Does anyone know of a method to use CRTP to count the number of subclasses of an object? Suppose we had a setup similar to the following one: template <typename T> class Object { .... }; const unsigned int ObjectSubClassCount = ...; class Subobject : public Object<SubObject> { .... }; class Second : public Object<Second> { .... }; and so on, such that, using TMP, we might have a constant ( ObjectSubClassCount ) that represents the total number of subclasses? Does anyone know a way to do this?

问题 When I run the code below: s = pandas.Series(['c', 'a', 'b', 'a', 'b']) print(s.value_counts()) Sometimes I get this: a 2 b 2 c 1 dtype: int64 And sometimes I get this: b 2 a 2 c 1 dtype: int64 e.g. the index order returned for equivalent counts is not the same. I couldn't reproduce this if the Series values are integers instead of strings. Why does this happen, and what is the most efficient way to get the same index order every time? I want it to still be sorted in descending order by

问题 I am trying to solve a difficult problem and am getting lost. Here's what I'm supposed to do: INPUT: file OUTPUT: dictionary Return a dictionary whose keys are all the words in the file (broken by whitespace). The value for each word is a dictionary containing each word that can follow the key and a count for the number of times it follows it. You should lowercase everything. Use strip and string.punctuation to strip the punctuation from the words. Example: >>> #example.txt is a file
