Sorry if I asked a duplicate question, but I couldn't find a solution for this error. I surfed around stackoverflow,gradle site, android blogs, google search but there wasn't a working solution for several hours.

问题 I have a question in regards to finding duplicates in a dataframe, and removing duplicates in a dataframe using a specific column. Here is what I am trying to accomplish: Is it possible to remove duplicates but keep the first 2? Here is an example of my current dataframe called df and take a look at the bracket notes I have placed below to give you an idea. Note: If 'Roll' = 1 then I want to look at the Date column, see if there is a second duplicate Date in that column... keep those two and

How to search Array for multiple values in PHP?

无人久伴 提交于 2019-11-28 09:42:13
I need to get the keys from values that are duplicates. I tried to use array_search and that worked fine, BUT I only got the first value as a hit. I need to get both keys from the duplicate values, in this case 0 and 2. The search result output as an array would be good. Is there a PHP function to do this or do I need to write some multiple loops to do it? $list[0][0] = "2009-09-09"; $list[0][1] = "2009-05-05"; $list[0][2] = "2009-09-09"; $list[1][0] = "first-paid"; $list[1][1] = "1"; $list[1][2] = "last-unpaid"; echo array_search("2009-09-09",$list[0]); You want array_keys with the search

Merge dictionaries retaining values for duplicate keys

问题 Given n dictionaries, write a function that will return a unique dictionary with a list of values for duplicate keys. Example: d1 = {'a': 1, 'b': 2} d2 = {'c': 3, 'b': 4} d3 = {'a': 5, 'd': 6} result: >>> newdict {'c': 3, 'd': 6, 'a': [1, 5], 'b': [2, 4]} My code so far: >>> def merge_dicts(*dicts): ... x = [] ... for item in dicts: ... x.append(item) ... return x ... >>> merge_dicts(d1, d2, d3) [{'a': 1, 'b': 2}, {'c': 3, 'b': 4}, {'a': 5, 'd': 6}] What would be the best way to produce a new

How do I use SELECT GROUP BY in DataTable.Select(Expression)?

雨燕双飞 提交于 2019-11-28 08:18:25
I try to remove the duplicate rows by select a first row from every group. For Example PK Col1 Col2 1 A B 2 A B 3 C C 4 C C I want a return: PK Col1 Col2 1 A B 3 C C I tried following code but it didn't work: DataTable dt = GetSampleDataTable(); //Get the table above. dt = dt.Select("SELECT MIN(PK), Col1, Col2 GROUP BY Col1, Col2); DataTable 's Select method only supports simple filtering expressions like {field} = {value} . It does not support complex expressions, let alone SQL/Linq statements. You can, however, use Linq extension methods to extract a collection of DataRow s then create a new

Finding duplicate integers in an array and display how many times they occurred

倾然丶 夕夏残阳落幕 提交于 2019-11-28 07:29:36
I'm working on a code that prints out duplicated integers from an array with the number of their occurrence. I'm not allowed to use LINQ, just a simple code. I think I'm so close but confused about how to get a correct output: class Program { static void Main(string[] args) { int[] array = { 10, 5, 10, 2, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11, 12, 12 }; int count = 1; for (int i = 0; i < array.Length; i++) { for (int j = i; j < array.Length - 1 ; j++) { if(array[j] == array[j+1]) count = count + 1; } Console.WriteLine("\t\n " + array[i] + "occurse" + count); Console.ReadKey(); } } } Since you can't

Count duplicates records in Mysql table?

时光毁灭记忆、已成空白 提交于 2019-11-28 07:26:17
I have table with, folowing structure. tbl id name 1 AAA 2 BBB 3 BBB 4 BBB 5 AAA 6 CCC select count(name) c from tbl group by name having c >1 The query returning this result: AAA(2) duplicate BBB(3) duplicate CCC(1) not duplicate The names who are duplicates as AAA and BBB. The final result, who I want is count of this duplicate records. Result should be like this: Total duplicate products ( 2 ) xdazz The approach is to have a nested query that has one line per duplicate, and an outer query returning just the count of the results of the inner query. SELECT count(*) AS duplicate_count FROM (

Clone JavaFX Node?

你离开我真会死。 提交于 2019-11-28 07:10:34
问题 I have created a Node ( AnchorPane ) in the JavaFX scene builder and was wondering how to clone it. I saw Duplicate/Clone Node in JavaFX 2.0 but I need to clone the Node without re-loading the fxml. Is there any way to achieve this in JavaFX 2? 回答1: You can place the component that needs to be duplicated in a separate .fxml file. Then you can load the separate file as many times as needed adding the nodes to the appropriate root in the main scene. Additionally you can edit an <fx:include
