range

问题 So basically I want to count the number of occurrences a floating point appears in a given list. For example: a list of grades (all scores out of 100) are inputted by the user and they are sorted in groups of ten. How many times do scores from 0-10, 10-20, 20-30.. etc) appear? Like test score distribution. I know I can use the count function but since I'm not looking for specific numbers I'm having trouble. Is there a away to combine the count and range? Thanks for any help. 回答1: To group the

问题 I'm using a content-editable iframe to create a syntax-highlighter in javascript and one of the most important things is to be able to indent code properly. The following code works just as it should in Firefox: // Create one indent character var range = window.getSelection().getRangeAt(0); var newTextNode = document.createTextNode(Language.tabChar); range.insertNode(newTextNode); range.setStartAfter(newTextNode); It creates a tab char and moves the cursor to the right side of the character.

问题 I would like to merge/combine two files, so that if an entry in column B of my first file falls into the range of columns B and C in my second file, the output will contain all of the information contained in both files. Like this: file 1 A B rs10 23353 rs100 10000 rs234 54440 file 2 A B C E235 20000 30000 E255 50000 60000 where, because 23353 falls between 20000 and 30000, and 54440 falls between 50000 and 60000 the output file would look like this: rs 23353 E235 20000 30000 rs234 54440 E255

问题 I've been looking on the internet for 4 hours and I just can't do it. My objectives : create a combo where I can sort my items and when I click on one of them, the item appears alone. In Excel, easy to do, but I can't do it in C#. I found this answer : Other topic, but I can't understand where the "this.Controls" comes from. Thanks for your help 回答1: if you want to use a validation for that purpose the following method was written by me to add a Validation and a small Infobox that appears

问题 The method I've devised so far is this: func randRange (lower : Int , upper : Int) -> Int { let difference = upper - lower return Int(Float(rand())/Float(RAND_MAX) * Float(difference + 1)) + lower } This generates random integers between lower and upper inclusive. 回答1: Here's a somewhat lighter version of it: func randRange (lower: Int , upper: Int) -> Int { return lower + Int(arc4random_uniform(UInt32(upper - lower + 1))) } This can be simplified even further if you decide this function

问题 I have a content editable Iframe I want to autolink it, like : My content editable Iframe look like i tried using regular expression in this Question i asked before. The function that i use in this question works fine, but actually it will replace all links including links in tags (IMG, existing A HREFs). But i dont want to use regx if i use regx convertion happens when i click any submit or save button. When a user paste's a url in a content editable Iframe it should automatically convert

问题 The range function in python3 takes three arguments two of them are optional. So the argumentlist looks like: [start], stop, [step] so this means (correct me if i'm wrong) there is a optional argument before an not-optional argument. But if i try to define a function like this i get this: >>> def foo(a = 1, b, c = 2): print(a, b, c) SyntaxError: non-default argument follows default argument is this something i can't do as a 'normal' python user, or can i somehow define such a function? Of

问题 I'm trying to find the largest prime factor of the number x, Python gives me the error that the range is too large. I've tried using x range but I get an OverflowError: Python int too large to convert to C long x = 600851475143 maxPrime = 0 for i in range(x): isItPrime = True if (x%i == 0): for prime in range(2,i-1): if (i%prime == 0): isItPrime = False if (isItPrime == True): if (i > maxPrime): maxPrime = i; print maxPrime 回答1: In old (2.x) versions of Python, xrange can only handle Python 2
