• python mysqldb string formatting

  - by Daniel

  How do I do this correctly: I want to do a query like this: query = """SELECT * FROM sometable order by %s %s limit %s, %s;""" conn = app_globals.pool.connection() cur = conn.cursor() cur.execute(query, (sortname, sortorder, limit1, limit2) ) results = cur.fetchall() All works fine but the order by %s %s is not putting the strings in correctly. It is putting the two substitutions in with quotes around them. So it ends up like: ORDER BY 'somecol' 'DESC' Which is wrong should be: ORDER BY somecol DESC Any help greatly appreciated!

• regex to check string is certain length

  - by Aly

  Hi, I am trying to write a regex to match pairs of cards (AA, KK, QQ ... 22) and I have the regex ([AKQJT2-9])\1. The problem I have is that this regex will match AA as well as AAbc etc. Is there a way to write the regex such that I can specify I want to match ([AKQJT2-9])\1 and only that (i.e. no more characters after). Thanks

• String formatting named parameters?

  - by Mark

  I know it's a really simple question, but I have no idea how to google it. how can I do print '<a href="%s">%s</a>' % (my_url) So that my_url is used twice? I assume I have to "name" the %s and then use a dict in the params, but I'm not sure of the proper syntax? just FYI, I'm aware I can just use my_url twice in the params, but that's not the point :)

• Complex String Processing - well complex to me

  - by percent20

  I am calling a web service and all I get back is a giant blob of text. I am left to process it myself. Problem is not all lines are necessarily the same. They each have 2 or 3 sections to them and they are similar. Here are the most common examples text1 [text2] /text3/ text1/test3 text1[text2]/text3 text1 [text2] /text /3 here/ I am not exactly sure how to approach this problem. I am not too good at doing anything advanced as far as manipulating strings. I was thinking using a regular expression might work, but not too sure on that either. If I can get each of these 3 sections broken up it is easier from there to do the rest. its just there doesn't seem to be any uniformity to the main 3 sections that I know how to work with.

• sql - datetime variable versus string representation of datetime variable

  - by BhejaFry

  Hi folks, I have a query that takes too long to respond when the search parameter happens to be a varchar datatype with date. However, if i convert varchar to datetime variable, the query runs fine. For ex: This takes too long. select count(id) from names where updateddate '1/5/2010' This runs fine. declare @dateparam datetime set @dateparam = convert(datetime, '1/5/2010',102) select count(id) from names where updateddate @dateparam What's the reason one runs fine but the other doesn't? TIA

• Perl, evaluate string lazily

  - by Mike

  Consider the following Perl code. #!/usr/bin/perl use strict; use warnings; $b="1"; my $a="${b}"; $b="2"; print $a; The script obviously outputs 1. I would like it to be whatever the current value of $b is. What would be the smartest way in Perl to achieve lazy evaluation like this? I would like the ${b} to remain "unreplaced" until $a is needed.

  I have a pretty large insert statement something like INSERT INTO multimedia (filename, regex, flag) VALUES (('adsfavr.jpg', '<div id="title">', 0), (...), (...)); How do I prepare the query for MySQL.It's too long to do it manually.

• Simple javascript string problem in ie6 and ie7

  - by Jeff Lamb

  I have a very simple function that takes a list of comma separated (x,y) points and imports them into a graph. I have FF, Chrome and IE8 installed. I use IETester to test for IE6 and IE7. // Import Data this.Import = function(data) { alert("Data in: "+data); var d; // Make sure the first and the last are start/ending parenthesis if ( (data[0] != '(') || (data[data.length-1] != ')') ) { alert("After if: "+data[0]+" "+data[data.length-1]); return false; } ... In Chrome, FF and IE8, I don't see the "After if:" alert. In IE6 and IE7, I see the following two alerts: Data in: (52,16),(100,90) After if: undefined undefined The "Data in" alert matches in all browsers. Any ideas?

• Tricky string transformation (hopefully) in LINQ

  - by Larsenal

  I'm hoping for a concise way to perform the following transformation. I want to transform song lyrics. The input will look something like this: Verse 1 lyrics line 1 Verse 1 lyrics line 2 Verse 1 lyrics line 3 Verse 1 lyrics line 4 Verse 2 lyrics line 1 Verse 2 lyrics line 2 Verse 2 lyrics line 3 Verse 2 lyrics line 4 And I want to transform them so the first line of each verse is grouped together as in: Verse 1 lyrics line 1 Verse 2 lyrics line 1 Verse 1 lyrics line 2 Verse 2 lyrics line 2 Verse 1 lyrics line 3 Verse 2 lyrics line 3 Verse 1 lyrics line 4 Verse 2 lyrics line 4 Lyrics will obviously be unknown, but the blank line marks a division between verses in the input.

• String munging in Objective-C with NSAttributedString.

  - by dreeves

  I have an NSAttributedString s and an integer i and I'd like a function that takes s and i and returns a new NSAttributedString that has a (stringified) i prepended to s. It looks like some combination of -stringWithFormat:, -initWithString:, and -insertAttributedString: would do it but I'm having trouble piecing it together without a lot of convolution and temporary variables. More generally, pointers to guides on making sense of NSAttributedString and NSMutableAttributedString would be awesome.

• Ruby delete method (string manipulation)

  - by brianheys

  I'm new to Ruby, and have been working my way through Mr Neighborly's Humble Little Ruby Guide. There have been a few typos in the code examples along the way, but I've always managed to work out what's wrong and subsequently fix it - until now! This is really basic, but I can't get the following example to work on Mac OS X (Snow Leopard): gone = "Got gone fool!" puts "Original: " + gone gone.delete!("o", "r-v") puts "deleted: " + gone Output I'm expecting is: Original: Got gone fool! deleted: G gne fl! Output I actually get is: Original: Got gone fool! deleted: Got gone fool! The delete! method doesn't seem to have had any effect. Can anyone shed any light on what's going wrong here? :-\

• Objective c string formatter for distances

  - by nevan

  I have a distance as a float and I'm looking for a way to format it nicely for human readers. Ideally, I'd like it to change from m to km as it gets bigger, and to round the number nicely. Converting to miles would be a bonus. I'm sure many people have had a need for one of these and I'm hoping that there's some code floating around somewhere. Here's how I'd like the formats: 0-100m: 47m (as a whole number) 100-1000m: 325m or 320m (round to the nearest 5 or 10 meters) 1000-10000m: 1.2km (round to nearest with one decimal place) 10000m +: 21km If there's no code available, how can I write my own formatter? Thanks

• How does string comparison work in OCAML?

  - by Steve Rowe

  From what I can tell, = and != is supposed to work on strings in OCAML. I'm seeing strange results though which I would like to understand better. When I compare two strings with = I get the results I expect: # "steve" = "steve";; - : bool = true # "steve" = "rowe";; - : bool = false but when I try != I do not: # "steve" != "rowe";; - : bool = true # "steve" != "steve";; (* unexpected - shouldn't this be false? *) - : bool = true Can anyone explain? Is there a better way to do this?

• parsing a string based on specified identifiers

  - by jml

  Let's say that I have the following text: input = "one aaa and bbb two bbbb er ... // three cccc" I would like to parse this into a group of variables that contain criteria = ["one", "two", "three"] v1,v2,v3 = input.split(criteria) I know that the example above won't work, but is there some utility in python that would allow me to use this sort of approach? I know what the identifiers will be in advance, so I would think that there has got to be a way to do this... Thanks for any help, jml

• String Manipulation: Spliting Delimitted Data

  - by Milli Szabo

  I need to split some info from a asterisk delimitted data. Data Format: NAME*ADRESS LINE1*ADDRESS LINE2 Rules: 1. Name should be always present 2. Address Line 1 and 2 might not be 3. There should be always three asterisks. Samples: MR JONES A ORTEGA*ADDRESS 1*ADDRESS2* Name: MR JONES A ORTEGA Address Line1: ADDRESS 1 Address Line2: ADDRESS 2 A PAUL*ADDR1** Name: A PAUL Address Line1: ADDR1 Address Line2: Not Given My algo is: 1. Iterate through the characters in the line 2. Store all chars in a temp variables until first * is found. Reject the data if no char is found before first occurence of asterisk. If some chars found, use it as the name. 3. Same as step 2 for finding address line 1 and 2 except that this won't reject the data if no char is found My algo looks ugly. The code looks uglier. Spliting using //* doesn't work either since name can be replaced with address line 1 If the data is *Address 1*Address2, split will create two indexes in the array where index 0 will have the value of Address 1 and index 2 will have the value of Address2. Where's the name. Was there a name? Any suggestion?
