delimiter

In a list like the one below: biglist = ['X', '1498393178', '1|Y', '15496686585007', '-82', '-80', '-80', '3', '3', '2', '|Y', '145292534176372', '-87', '-85', '-85', '3', '3', '2', '|Y', '11098646289856', '-91', '-88', '-89', '3', '3', '2', '|Y', '35521515162112', '-82', '-74', '-79', '3', '3', '2', '|Z', '0.0', '0.0', '0', '0', '0', '0', '0', '4', '0', '154'] There could be some numerical elements preceded by a character. I would like to break this into sub-lists like below: smallerlist = [ ['X', '1498393', '1'], ['Y', '1549668', '-82', '-80', '-80', '3', '3', '2', ''], ['Y', '1452925', '-87

The software I am using produces log files with a variable number of lines of summary information followed by lots of tab delimited data. I am trying to write a function that will read the data from these log files into a data frame ignoring the summary information. The summary information never contains a tab, so the following function works: read.parameters <- function(file.name, ...){ lines <- scan(file.name, what="character", sep="\n") first.line <- min(grep("\\t", lines)) return(read.delim(file.name, skip=first.line-1, ...)) } However, these logfiles are quite big, and so reading the file

recently i've been searching for a solution to the following situation: I have mysql table with structure: CREATE TABLE IF NOT EXISTS `battles` ( `id` int(11) NOT NULL AUTO_INCREMENT, `active` tinyint(1) NOT NULL, `created` datetime NOT NULL, `modified` datetime NOT NULL, `begindate` datetime NOT NULL, `enddate` datetime NOT NULL, PRIMARY KEY (`id`), ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1 ; Every battle has begindate and enddate. Begindate is datetime of insert and usually enddate is three days later. I would like to create a mysql event that stops the

How do I convert "1,,2'3,4'" into a list? Commas separate the individual items, unless they are within quotes. In that case, the comma is to be included in the item. This is the desired result: ['1', '', '2', '3,4'] . One regex I found on another thread to ignore the quotes is as follows: re.compile(r'''((?:[^,"']|"[^"]*"|'[^']*')+)''') But this gives me this output: ['', '1', ',,', "2'3,4'", ''] I can't understand, where these extra empty strings are coming from, and why the two commas are even being printed at all, let alone together. I tried making this regex myself: re.compile(r'''(, | "[^

I need to be able to figure out which delimiter is being used in a csv file (comma, space or semicolon) in my Ruby project. I know, there is a Sniffer class in Python in the csv module that can be used to guess a given file's delimiter. Is there anything similar to this in Ruby ? Any kind of help or idea is greatly appreciated. Looks like the py implementation just checks a few dialects: excel or excel_tab. So, a simple implementation of something that just checks for "," or "\t" is: COMMON_DELIMITERS = ['","',"\"\t\""] def sniff(path) first_line = File.open(path).first return nil unless first

import java.io.*; import java.util.*; class usingDelimiters { public static void main(String args[]) { Scanner dis=new Scanner(System.in); int a,b,c; a=dis.nextInt(); b=dis.nextInt(); c=dis.nextInt(); System.out.println("a="+a); System.out.println("b="+b); System.out.println("c="+c); } } This program is working fine when my input is 1 2 3 (separated by space) But, how to modify my program when my input is 1,2,3 (separated by commas) you can use the nextLine method to read a String and use the method split to separate by comma like this: public static void main(String args[]) { Scanner dis=new

This question already has answers here : Closed 4 years ago . Passing a varchar full of comma delimited values to a SQL Server IN function (22 answers) I would like retrieve a certain users from a full list of a temp table #temptable. The query is like this: DECLARE @List varchar(max) SELECT @List = coalesce(@List + ',','') + '''' + StaffCode + '''' FROM tblStaffs SELECT UserName FROM #temptable WHERE #temptable.StaffCode IN (@List) I can tell @List is in a right format: 'AAA','ABB','BBB','CCC','DDD','MMM' And if I change it to WHERE #temptable.StaffCode IN ('AAA','ABB','BBB','CCC','DDD','MMM'
