duplicates

I have a list of items like this: ['T1','T2','T2','T2','T2','T3','T3' ] I need to make sure that duplicates are renamed with a progressive letter added like this: ['T1','T2A','T2B','T2C','T2D','T3A','T3B'] but only if there is more than 1 occurrence of the same item. Also, is it possible to do so without generating a new list? Any ideas? from collections import Counter from string import ascii_uppercase as letters def gen(L): c = Counter(L) for elt, count in c.items(): if count == 1: yield elt else: for letter in letters[:count]: yield elt + letter Now: >>> L = ['T1','T2','T2','T2','T2','T3',

I have the following XML and I want to process it so that I do not get duplicates in the result set. I have simplified the problem to make it easier to understand. Also how can I use the results of one template as part of the input for another? This: <LINES xmlns:set="http://exslt.org/sets"> <STDINSTRSEQ>0</STDINSTRSEQ> <STDINSTRSEQ>1</STDINSTRSEQ> <STDINSTRSEQ>2</STDINSTRSEQ> </LINES> is the desired result. <STDINSTRSEQ> is the name of the field that should be treated as the key. I have provided the sample data here. <PURCHASEORDER> <POHEADER> <BODID>infor-nid:Elevon:SCMCS::12654_0198617S12

Problem is this, take two lists, say for example these two: a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89] b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13] And write a program that returns a list that contains only the elements that are common between the lists (without duplicates). Make sure your program works on two lists of different sizes. Here's my code: a = [1, 1, 2, 2, 3, 5, 8, 13, 21, 34, 55, 89] b = [1, 2, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13] c = [] for i in a: if i in b and i not in c: c.append([i]) print(c) My output is still giving me duplicates despite the 'i not in c' statement.

Like many other questions on here, I'm attempting to remove duplicates from a list. However, when I execute code that other answers claim work I get the following error: TypeError: unhashable type: 'list' on the following line of code: total_unique_words = list(set(total_words)) Does anyone know a possible solution to this problem? Is this because in most cases the original structure isn't a list? Thanks! total_words must contain sublists for this error to occur. Consider: >>> total_words = ['red', 'red', 'blue'] >>> list(set(total_words)) ['blue', 'red'] >>> total_words = ['red', ['red',

I have following array where I am trying to merge the elements which has shelf and weight value as duplicate and sum the value of piece key. Array ( [0] => Array ( [shelf] => Left [weight] => 10.000 [piece] => 1 ) [1] => Array ( [shelf] => Right [weight] => 04.000 [piece] => 12 ) [2] => Array ( [shelf] => Right [weight] => 04.000 [piece] => 4 ) [3] => Array ( [shelf] => Right [weight] => 07.000 [piece] => 8 ) ) Currently I am getting following desired output with help of following SQL statement by creating the temporary table with following fields shelf , weight and piece and inserting all the

I've inherited a database and I'm having trouble constructing a working SQL query. Suppose this is the data: [Products] | Id | DisplayId | Version | Company | Description | |---- |----------- |---------- |-----------| ----------- | | 1 | 12345 | 0 | 16 | Random | | 2 | 12345 | 0 | 2 | Random 2 | | 3 | AB123 | 0 | 1 | Random 3 | | 4 | 12345 | 1 | 16 | Random 4 | | 5 | 12345 | 1 | 2 | Random 5 | | 6 | AB123 | 0 | 5 | Random 6 | | 7 | 12345 | 2 | 16 | Random 7 | | 8 | XX45 | 0 | 5 | Random 8 | | 9 | XX45 | 0 | 7 | Random 9 | | 10 | XX45 | 1 | 5 | Random 10 | | 11 | XX45 | 1 | 7 | Random 11 |

I joined a table to itself to find duplicate rows select a.data, a.rowNumber, b.rowNumber from DuplicateRows as a join DuplicateRows as b on a.data = b.data and a.Id != b.Id group by a.data, a.rowNumber, b.rowNumber This query gives the results like "content" | 1 | 2 "content" | 1 | 6 "content" | 2 | 1 "content" | 2 | 6 ...and so on Howcome I rewrite it to have results formed like "content" | 1 | 2, 6 EDIT I think the question should be a little bit corrected. You see I don't want to get the inversed result, I mean I just want to get one entry `1 -> 2, 6` not `1 -> 2, 6 and `2 -> 1, 6` Thanks!

I have an issue with my TableView and its items. I have created a small Dialog window to display warnings about my app, and inside the Dialog I have a TableView which displays the name of the warning and some information about it upon clicking on a button. I have created a WarningUtil class ( Singleton pattern) just to open / close the Dialog . The relevant code follows. The constructor of the WarningUtil class (called once only) : private WarningUtil(RootCtrl rootCtrl) { this.rootCtrl = rootCtrl; warnings = new HashMap<>(); setupWarningCallbacks(); // not relevant setupTable(); setupColumns()
