duplicate-removal

问题 My script for plotting creates two legends for each label. I do not know how to make legend() not duplicate. I checked on stackoverflow and found two methods. But I could not implement them here. Any ideas? Matplotlib: Don't show errorbars in legend Stop matplotlib repeating labels in legend symbols = [u'\u2193'] #Plotting our vsini values for i, symbol in enumerate(symbols): for x0,y0 in zip(vsini_slit_cl, vsini_slit): plt.text(x0,y0, symbol, fontname='STIXGeneral', size = 10, va='center',

问题 Need help in removing the duplicate node from the input xml using XSLT This is how my XML looks like, <?xml version="1.0"?> <NodeA NodeAattr="123"> <NodeB NodeBattr="456"></NodeB> <NodeC> <NodeD="ValueD"> <NodeE Name="ValueABC"> <NodeF Value="0"></NodeF > </NodeE > <NodeE Name="ValueABC"> <NodeF Value="0"></NodeF > </NodeE> </NodeD> </NodeC> </NodeA> My final output should look like <NodeA NodeAattr="123"> <NodeB NodeBattr="456"></NodeB> <NodeC> <NodeD="ValueD"> <NodeE Name="ValueABC"> <NodeF

问题 I am trying to run a query that joins a table against itself and does fuzzy string comparison (using trigram comparisons) to find possible company name matches. My goal is to return records where the trigram similarity of one record's company name (ref_name field) matches another record's company name. Currently, I have my threshold set to 0.9 so it will only bring back matches that are very likely to contain the a similar string. I know that self joins can result in many comparisons by

问题 Having approximately 600GB of photos collected over 13 years - now stored on freebsd zfs/server. Photos comes from family computers, from several partial backups to different external USB HDDs, reconstructed images from disk disasters, from different photo manipulation softwares (iPhoto, Picassa, HP and many others :( ) in several deep subdirectories - shortly = TERRIBLE MESS with many duplicates. So in the first i done: searched the the tree for the same size files (fast) and make md5

问题 Consider the following list of tuples: val input= List((A,B), (C,B), (B,A)) and assuming that the elements (A,B) and (B,A) are the same and therefore are duplicates, what is the efficient way (preferably in Scala) to eliminate duplicates from the list above. That means the desired output is an another list: val deduplicated= List((A,B), (C,B)) Thanks in advance! p.s: this is not a home work ;) UPDATE: Thanks to all! The "set"-solution seems to be the preferable one. 回答1: You could try it with

问题 I have an ordinary Python list that contains (multidimensional) numPy arrays, all of the same shape and with the same number of values. Some of the arrays in the list are duplicates of earlier ones. I have the problem that I want to remove all the duplicates, but the fact that the data type is numPy arrays complicates this a bit... • I can't use set() as numPy arrays are not hashable. • I can't check for duplicates during insertion, as the arrays are generated in batches by a function and

问题 So I understand how to remove duplicates in a list when it comes to strings and int, etc by using Distinct() from Linq. But how do you remove duplicates based on a specific attribute of an object? For example, I have a TimeMetric class. This TimeMetric class has two attributes: MetricText and MetricTime . I have a list of TimeMetrics called MetricList . I want to remove any duplicates TimeMetric with the same MetricText attribute. The TimeMetric value can be the same but if any TimeMetric has

问题 I have list of products (3 million items) without IDs - only titles. But I don't know which titles already exist in DB. New products (about 2.9 million items) must be added into DB. After that I must know ID for each products (new and existing). Is there the fastest way to do it in PostgreSQL? I can change DB as needed (add default values, add columns etc.). 回答1: Import data COPY everything to a temporary staging table and insert only new titles into your target table. CREATE TEMP TABLE tmp

问题 I have table of duplicate records like Now I want only one record from duplicate records which has latest created date as How can I do it ? 回答1: use row_number() : select EnquiryId, Name, . . . from (select t.*, row_number() over (partition by enquiryID order by CreatedDate desc) as seqnum from table t ) t where seqnum = 1; 回答2: Use ROW_NUMBER function to tag the duplicate records ordered by CreatedDate, like this: ;with CTE AS ( select *, row_NUMBER() over( partition by EnquiryID -- add

问题 I have a tab-delimited input.txt file like this A B C A B D E F G E F T E F K These are tab-delimited. I want to remove duplicates only when multiple rows have the same 1st and 2nd columns. So, even though 1st and 2nd rows are different in 3rd column, they have the same 1st and 2nd columns, so I want to remove "A B D" that appears later. So output.txt will be like this. A B C E F G If I was to remove duplicates in usual way, I just make the lists into "set" function, and I am all set. But now
