  • finding a string of random characters (with possible errors) within a large string of random charact

    - by mike
    I am trying to search a large string w/o spaces for a smaller string of characters. using regex I can easily find perfect matches but I can't figure out how to find partial matches. by partial matches i mean one or two extra characters in the string or one or two characters that have been changed, or one of each. the first and last characters will always match though. this would be similar to a spell checker but there are no spaces and the strings dont contain actual words, just random hex digits. i figured a way to find the string if there are no extra characters using indexOf(string.charAt(0)) and indexOf(charAt(string.length()-1) and looping through the characters between the two indexes. but this can be problematic when dealing with randomized characters because of the possibility of finding the first and last characters at the correct spacing but none of the middle characters matching. i've been scratching my head for hours on this issue. any ideas?

  • Having problems with a mask in C#

    - by Nard Dog
    I guess this would be a DevExpress mask, but here is what I have: var dlEdit = new DevExpress.XtraEditors.Repository.RepositoryItemTextEdit(); dlEdit.Mask.MaskType = MaskType.RegEx; dlEdit.Mask.EditMask = "\\d{1,10}"; I'm trying to get a number that can be up to 10 digits in length that WILL accept leading 0's, as it is now it will show the leading 0's (ex. 0032421243) until the field is clicked off in which case it removes them. I tried a numeric masktype but same thing only it wouldn't let me enter the 0's to start with at all. I thought this would be my answer but this custom type isn't. Can someone point me in the right direction for what I need? Maybe a different type of mask or something?

  • Match multiline regex in file object

    - by williamx
    How can I extract the groups from this regex from a file object (data.txt)? import numpy as np import re import os ifile = open("data.txt",'r') # Regex pattern pattern = re.compile(r""" ^Time:(\d{2}:\d{2}:\d{2}) # Time: 12:34:56 at beginning of line \r{2} # Two carriage return \D+ # 1 or more non-digits storeU=(\d+\.\d+) \s uIx=(\d+) \s storeI=(-?\d+.\d+) \s iIx=(\d+) \s avgCI=(-?\d+.\d+) """, re.VERBOSE | re.MULTILINE) time = []; for line in ifile: match = re.search(pattern, line) if match: time.append(match.group(1)) The problem in the last part of the code, is that I iterate line by line, which obviously doesn't work with multiline regex. I have tried to use pattern.finditer(ifile) like this: for match in pattern.finditer(ifile): print match ... just to see if it works, but the finditer method requires a string or buffer. I have also tried this method, but can't get it to work matches = [m.groups() for m in pattern.finditer(ifile)] Any idea?

  • How do I make this simple list comprehension?

    - by Carson Myers
    I'm new to python, and I'm trying to get to know the list comprehensions better. I'm not even really sure if list comprehension is the word I'm looking for, since I'm not generating a list. But I am doing something similar. This is what I am trying to do: I have a list of numbers, the length of which is divisible by three. So say I have nums = [1, 2, 3, 4, 5, 6] I want to iterate over the list and get the sum of each group of three digits. Currently I am doing this: for i in range(0, len(nums), 3): nsum = a + b + c for a, b, c in nums[i, i+3] print(nsum) I know this is wrong, but is there a way to do this? I'm sure I've overlooked something probably very simple... But I can't think of another way to do this.

  • DateTime: Require the user to enter a time component

    - by Heinzi
    Checking if a user input is a valid date or a valid "date + time" is easy: .NET provides DateTime.TryParse (and, in addition, VB.NET provides IsDate). Now, I want to check if the user entered a date including a time component. So, when using a German locale, 31.12.2010 00:00 should be OK, but 31.12.2010 shouldn't. I know I could use DateTime.TryParseExact like this: Dim formats() As String = {"d.M.yyyy H:mm:ss", "dd.M.yyyy H:mm:ss", _ "d.MM.yyyy H:mm:ss", "d.MM.yyyy H:mm:ss", _ "d.M.yyyy H:mm", ...} Dim result = DateTime.TryParseExact(userInput, formats, _ Globalization.CultureInfo.CurrentCulture, ..., result) but then I would hard-code the German format of specifying dates (day dot month dot year), which is considered bad practice and will make trouble should we ever want to localize our application. In addition, formats would be quite a large list of all possible combinations (one digit, two digits, ...). Is there a more elegant solution?

  • Databinding int32 to MaskedEditExtender enabled TextBox

    - by Zach Skinner
    I have a master/detail scheme for editing an asp:GridView using an asp:DetailsView. One of my fields is for a phone number of type int64 (always 10 digits). I would like this field to always be displayed as (###)###-####. My issue is the first digit in the phone number is always truncated for my edit item field which I used a MaskedEditExtender to achieve the formatting. Here is my EditItemTemplate for the details view: <cc1:MaskedEditExtender TargetControlID="edtPROJ_Leader_Phone" Mask="(999)999-9999" runat="server" ClearMaskOnLostFocus="false" ClipboardEnabled="true" MaskType="Number" /> <asp:TextBox ID="edtPROJ_Leader_Phone" runat="server" Text='<%# Bind("PROJ_Leader_Phone") %>' ></asp:TextBox> When my details view is displayed for editing, the text box displays(_23)456-7890 for the integer 1234567890. Also worth noting that if the property MaskType="Number" is removed, the textbox shows: (234)567-890_. I would of course have the textbox show (123)-546-67890 after binding.

  • Regex for splitting a german address into its parts

    - by Christian
    Good evening, I'm trying to splitting the parts of a german address string into its parts via Java. Does anyone know a regex or a library to do this? To split it like the following: Name der Straße 25a 88489 Teststadt to Name der Straße|25a|88489|Teststadt or Teststr. 3 88489 Beispielort (Großer Kreis) to Teststr.|3|88489|Beispielort (Großer Kreis) It would be perfect if the system / regex would still work if parts like the zip code or the city are missing. Is there any regex or library out there with which I could archive this? EDIT: Rule for german addresses: Street: Characters, numbers and spaces House no: Number and any characters (or space) until a series of numbers (zip) (at least in these examples) Zip: 5 digits Place or City: The rest maybe also with spaces, commas or braces

  • Decoding a compressed short string; uncertain on compression used - Updated

    - by James
    Hi, I have a program that is compressing a string in an unknown way. I know a few inputs and the output produced, but I am not sure what is being used to compress the string. Here are my examples. (just 38 x a, no spaces or anything else) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" Out: "026900211AA63000026900"   (just 32 x a) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" Out: "0209001c1aa7a000020900" (31 x a, then 1 b) In: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaab" Out: "0209000177c553c000020900" (31 x b, then 1 a) In: "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbba" Out: "0209001e7754f38000020900" In: "Hey wot u doing 2day u wanna do something" Out: "02990011C7C62E78CE6B8E3ACD83E81B37C5C5A6B9D1E1B06963DB5E71155C1000029900" (same as previous string, but with a space at the end) In: "Hey wot u doing 2day u wanna do something " Out: "02A90012C7718B9E339AE2EB360FA02CDF17177A674786DF4B1EDAF388AAE08000000002A90000" The only definite thing I can see so far is digit 2 and 3 are the amount of characters (hex value), ie first one is 26 = 38 Also the first 6 digits are repeated at the end Any help / advice would be great, thanks!

  • Replace values in a dataframe based on another factor which contains NA's in R

    - by PaulHurleyuk
    I have a dataframe which contains (among other things) a numeric column with a concentration, and a factor column with a status flag. This status flag contains NA's. Here's an example df<-structure(list(conc = c(101.769, 1.734, 62.944, 92.697, 25.091, 27.377, 24.343, 55.084, 0.335, 23.280), status = structure(c(NA, NA, NA, NA, NA, NA, 2L, NA, 1L, NA), .Label = c("<LLOQ", "NR"), class = "factor")), .Names = c("conc", "status"), row.names = c(NA, -10L), class = "data.frame") I want to replace the concentration column with a string for some values of the flag column, or with the concentration value formatted to a certain number of significant digits. When I try this ifelse(df$status=="NR","NR",df$conc) The NA's in the status flag don't trigger either the true or false condition (and return NA) - as the documentation suggests it will. I could loop over the rows and use IF then else on each one but this seems inefficient. Am I missing something ? I've tried as.character(df$status) as well which doesn't work. My mojo must be getting low....

  • Significant figures in the decimal module

    - by Jason Baker
    So I've decided to try to solve my physics homework by writing some python scripts to solve problems for me. One problem that I'm running into is that significant figures don't always seem to come out properly. For example this handles significant figures properly: from decimal import Decimal >>> Decimal('1.0') + Decimal('2.0') Decimal("3.0") But this doesn't: >>> Decimal('1.00') / Decimal('3.00') Decimal("0.3333333333333333333333333333") So two questions: Am I right that this isn't the expected amount of significant digits, or do I need to brush up on significant digit math? Is there any way to do this without having to set the decimal precision manually? Granted, I'm sure I can use numpy to do this, but I just want to know if there's a way to do this with the decimal module out of curiosity.

  • Decimal Base Conversion using PYTHON

    - by Butinyane More
    PROBLEM DESCRIPTION Given a decimal number, and a new base to represent it in. If the base is larger than 10, use capital letters for the digits(that is, A is 10, B is 11 and so forth). The decimal number given, and the new base, will both be integer values, separated by a space. The base to convert to will always be smaller than or equal to 30. Please create a program that will convert a decimal number to any base in this instance. When evaluating the program the sample input must something like: 18 2 and the program must output the following: 10010 Please i beg of you to send me a solution to this problem as soon as possible.

  • Modify cmd.exe properties using the command prompt

    - by CodexArcanum
    Isn't that nicely recursive? I've got a portable command prompt on my external drive, and it has a nice .bat file to configure some initial settings, but I'd like more! Here's what I know how to set from .bat: Colors = (color XY) where x and y are hex digits for the predefined colors Prompt = (prompt $p$g) sets the prompt to "C:\etc\etc " the default prompt Title = (title "text") sets the window title to "text" Screen Size = (mode con: cols=XX lines=YY) sets the columns and lines size of the window Path = (SET PATH=%~d0\bin;%PATH%) sets up local path to my tools and appends the computer's path So that's all great. But there are a few settings I can't seem to set from the bat. Like, how would I set these up wihtout using the Properties dialogue: Buffer = not screen size, but the buffer Options like quick edit mode and autocomplete Popup colors Font. And can you use a font on the portable drive, or must it be installed to work? Command history options

  • Regex question: Why isn't this matching?

    - by AllenG
    I have the following regex: (?<=\.\d+?)0+(?=\D|$) I'm running it against a string which contains the following: SVC~NU^0270~313.3~329.18~~10~~6.00: When it runs, it matches the 6.00 (correctly) which my logic then trims by one zero to turn into 6.0. The regex then runs again (or should) but fails to pick up the 6.0. I'm by no means an expert on Regex, but my understanding of my expression is that it's looking for a decimal with 1 or more optional (so, really zero or more) digits prior to one or more zeros which are then followed by any non-digit character or the line break. Assuming that interpretation is correct, I can't see why it wouldn't match on the second pass. For that matter, I'm not sure why my Regex.Replace isn't matching the full 6.00 on the first pass and removing both of the trailing zeros... Any suggestions?

  • How do I get a TextBox to only accept numeric input in WPF?

    - by Giffyguy
    I'm looking to accept digits and the decimal point, but no sign. I've looked at samples using the NumericUpDown control for WinForms, and this sample of a NumericUpDown custom control from Microsoft. But so far it seems like NumericUpDown (supported by WPF or not) is not going to provide the functionality that I want. The way my app is designed, nobody in their right mind is going to want to mess with the arrows. They don't make any practical sense, in the context of my app. So I'm looking for a simple way to make a standard WPF TextBox accept only the characters that I want. Is this possible? Is it practical? Thanks, SO!

  • How can I process command line arguments in Python?

    - by photographer
    What would be an easy expression to process command line arguments if I'm expecting anything like 001 or 999 (let's limit expectations to 001...999 range for this time), and few other arguments passed, and would like to ignore any unexpected? I understand if for example I need to find out if "debug" was passed among parameters it'll be something like that: if 'debug' in argv[1:]: print 'Will be running in debug mode.' How to find out if 009 or 575 was passed? All those are expected calls: python script.py python script.py 011 python script.py 256 debug python script.py 391 xls python script.py 999 debug pdf At this point I don't care about calls like that: python script.py 001 002 245 568 python script.py some unexpected argument python script.py 0001 python script.py 02 ...first one - because of more than one "numeric" argument; second - because of... well, unexpected arguments; third and fourth - because of non-3-digits arguments.

  • Integer comparison as string

    - by J Pollack
    Hi I have an integer column and I want to find numbers that start with specific digits. For example they do match if I look for '123': 1234567 123456 1234 They do not match: 23456 112345 0123445 Is the only way to handle the task by converting the Integers into Strings before doing string comparison? Also I am using Postgre regexp_replace(text, pattern, replacement) on numbers which is very slow and inefficient way doing it. The case is that I have large amount of data to handle this way and I am looking for the most economical way doing this.

  • not readable PDF files

Extractor (PDFBox library) returns a string like this: "¦xDn¦if|d+gDF"Ti&cD+lh d FÁhis~n +xd f«"d¦ffih »h" or "10a61a91a22a25a3a27a17a23a20a8a13a14a61a25a17" I was checking each file that makes this extraction's problem and all these files' text also can not be copy-pasted from PDF Reader (Adobe Reader and FoxIt reader). Viewing them in this readers is enabled, but after selecting its content and copying to the clipboard I get the same wrong text (as described above - strings of not semanticaly correct chars or strings of digits and letters) Could anybody help me???

  • SQL Server won't perform regular expression validation on XML column

I have an email address regex working fine, but can't get this simple numerical regex to work.

  • how to prevent white spaces in a regular expression regex validation

  • SSIS - How do I see/set the field types in a Recordset?

    - by thursdaysgeek
    I'm looking at an inherited SSIS package, and a stored procedure is sending records to a recordset called USER:NEW_RECORDS. It's of type Object, and the value is System.Object. It is then used for inputting that data to a SQL table. We're getting an error, because it seems that the numeric results of the stored procedure are being put in a DT_WSTR field, and then failing when it is then put into a decimal field in the database. Most of the records are working, but one, which happens to have a longer number of decimal digits, is failing. I want to see exactly what my SSIS recordset field types are, and probably change them, so I can force the data to be truncated properly and copied. Or, perhaps, I'm not even looking at this correctly. The data is put into the recordset using a SQL Task that executes the stored procedure.
