compare

问题 I want to do what StackOverflow is doing which is saying exactly how long it's been since the last post. There is a catch though, SO displays certain information based on how long the ago the last post was - for example, if the post was less than a day ago, they post how many hours ago the last post was; if the post was less than an hour ago they post how many minutes ago it was, etc. I'm working with a MYSQL DateTime field in the following format: 2012-09-19 13:28:45 I want to compare the

问题 I have a CSV with 44 columns and I have a table with 21 columns. Need to check of the columns in CSV along with the data matches with columns and data in database table I have created 2 class (one with main) where I have read the CSV file and stored the values in Key - Value pair. I have another class where I am executing select query to get the result. Now, got stuck with how should I be comparing these 2 things based on columns and its data Expected: No of columns in csv along with data

问题 a while ago i asked a question about comparing 2 dicts to eachother, in order to detect same key's and keep the highest value of duplicates. this community came with the a soltion which allowed me to compare 2 dicts to eachother and store the highest value of it in a new dict, which i can then compare to another dict if neccesary. but as the number of dicts are getting higher, the code itself keeps getting larger. for key in dict1: if key not in dict2 or dict1[key] > dict2[key]: dict2[key] =

问题 I have a stupid thing, but I really can´t see what am I missing: I have a test: @Test public void testeBerechneRendite() { get("/rendite?jahresnettomiete=8000&kaufpreis=100000&nebenkosten=500") .then().body(is(closeTo(0.079, 0.01))); } Error is: Response body doesn't match expectation. Expected: is a numeric value within <0.01> of <0.079> Actual: 0.07960199004975124 It seams I don`t understand the closeTo(double, double). From my understanding all numbers between 0.069 and 0.089 should be

问题 I have a static Array and a static method in my class and via this method I push some functions in the array. The method is called on timeline so when I play the frame twice it will push the function twice and so on. Question : How can I check if the function exists and prevent duplication? ( it is like addeventlistener ) 回答1: short version: don't code on the timeline. long version: if you're lucky the functions would be the same, so it's possible to compare them using the == operator. but as

问题 I have a matrix where each row of numbers represent values for a person.... person = 98 206 35 114 60 206 28 52 100 210 31 116 69 217 26 35 88 213 42 100 (The numbers I have here aren't really the numbers that I have) I want to compare array person1 = [93 208 34 107] with each row of the person . I find out which array is bigger than the other, then I divide the smaller by the larger. If the quotient is greater than or equal to 0.85 then there is a match and the name of the person will print

问题 I have a generic with some filenames (LIST1) and another biggeneric with a full list of names (LIST2). I need to match names from LIST1 to similar ones in LIST2. For example LIST1 - **MAIZE_SLIP_QUANTITY_3_9.1.aif** LIST 2 1- TUTORIAL_FAILURE_CLINCH_4.1.aif 2- **MAIZE_SLIP_QUANTITY_3_5.1.aif** 3- **MAIZE_SLIP_QUANTITY_3_9.2.aif** 4- TUTORIAL_FAILURE_CLINCH_5.1.aif 5- TUTORIAL_FAILURE_CLINCH_6.1.aif 6- TUTORIAL_FAILURE_CLINCH_7.1.aif 7- TUTORIAL_FAILURE_CLINCH_8.1.aif 8- TUTORIAL_FAILURE

问题 $first = 1,2,3,4,5; $second = 1,3,5,6; I need to get difference of those two, so that result would be like: $result = 2,4,6; 回答1: Assuming you mean $first = "1,2,3,4,5"; $second = "1,3,5,6"; then try $first_array = explode(",", $first); $second_array = explode(",", $second); $result_array = array_merge(array_diff($first_array, $second_array), array_diff($second_array, $first_array)); $result = implode("," $result_array); 回答2: try this: implode(',',array_diff(explode(',',$first),explode(',',

问题 I have 2 csv files 1.csv spain;russia;japan italy;russia;france 2.csv spain;russia;japan india;iran;pakistan I read both files and add data to lists var lst1= File.ReadAllLines("1.csv").ToList(); var lst2= File.ReadAllLines("2.csv").ToList(); Then I find all unique strings from both lists and add it to result lists var rezList = lst1.Except(lst2).Union(lst2.Except(lst1)).ToList(); rezlist contains this data [0] = "italy;russia;france" [1] = "india;iran;pakistan" At now I want to compare, make

问题 For starters I've only been playing with python for about a 2 weeks now and im relatively new to its proccessess, I'm trying to create a script that compares two directories with subdirectories and prints out ANY changes. I've read articles on hear about using os.walk to walk the directories and I've managed to write the script that prints all the files in a directory and its subdirectories in a understandable manner. I've also read on here and learned how to compare two directories but it
