  • Writing to CSV issue in Spyder

    - by 0003
    I am doing the Kaggle Titanic beginner contest. I generally work in Spyder IDE, but I came across a weird issue. The expected output is supposed to be 418 rows. When I run the script from terminal the output I get is 418 rows (as expected). When I run it in Spyder IDE the output is 408 rows not 418. When I re-run it in the current python process, it outputs the expected 418 rows. I posted a redacted portion of the code that has all of the relevant bits. Any ideas? import csv import numpy as np csvFile = open("/train.csv","ra") csvFile = csv.reader(csvFile) header = csvFile.next() testFile = open("/test.csv","ra") testFile = csv.reader(testFile) testHeader = testFile.next() writeFile = open("/gendermodelDebug.csv", "wb") writeFile = csv.writer(writeFile) count = 0 for row in testFile: if row[3] == 'male': do something to row writeFile.writerow(row) count += 1 elif row[3] == 'female': do something to row writeFile.writerow(row) count += 1 else: raise ValueError("Did not find a male or female in %s" % row)

    - by avi cohen
    hello, i'm beginner at android development. i want to create an activity, which shows a question with 4 answers, and at the bottom of the screen i want to place a timer. i have already found timer example, and i created a question with the answers. the problem that they are 2 different projects and activities, and i am looking for the best way to implement it. i think i can't show 2 activities on one screen, but i can show 2 views or shell i use the ViewGroup, or maybe to copy-paste one of the activities code to another ( its the easiest way but probably the most ugliest way to implement it). please tell me what is the best way, that i will study and not to waste time to study all the ways and only then to choose one of them. thanks!

  • Java application if/case recommendation

    - by Jesse
    I am writing an application for a Java course. I am a complete beginner and am just going off material I have learned from the course and from the web. The application is exhibiting some behavior and I am not sure what is causing it. The application is GUI based and does calculations on user input. For the action listener section, I have a set of If statements such as: "if this button do this if this button do this" All in a row like that. It seems as if the application is running ALL the if statements instead of running the one that corresponds with the button pressed. Would I be better off using a case/switch structure for this sort of thing? I can post my code if necessary, I am new around this site and am not sure if that thing is acceptable.

  • Eclipse + AppEngine =? autocomplete

    - by Brandon Watson
    I was doing some beginner AppEngine dev on a Windows box and installed Eclipse for that. I liked the autocompletion I got with the objects and functions. I moved my dev environment over to my Macbook, and installed Eclipse Ganymede. I installed the AppEngine SDK and Eclipse plug in. However, when I am typing out code now, the autocomplete isn't functioning. Did I miss a step? UPDATE Just to add to this: the line: import cgi appears to give me what I need. When I type "cgi." I get all of the auto complete. However, the lines: from google.appengine.api import users from google.appengine.ext import webapp from google.appengine.ext.webapp.util import run_wsgi_app from google.appengine.ext import db don't give me any auto complete. If I type "users." there is no auto complete.

  • Windows Shell Programming book suggestion

    - by Lijo
    Hi, I am a web developer using C#. I would like to experiment with Windows shell programming in C#. Many people suggests that using managed applications for shell program, is dangerous. (Creation of separate instances for each process versus in process shell. Also version dependency) Frankly speaking, I am totally new to shell. Is there a book available, that will treat these topics; both through managed code and unmanaged code (but mostly towards managed code)? It would be great if that book is concise , for beginner and giving theoretical background of the shell. Please suggest…. Thanks Lijo

  • Parsing NTFS Partition in C

    - by DooriBar
    Hello all, I'm just a beginner and I have a need to parse a NTFS partition for the purpose of extracting Security Descriptors. (I been trying to use the native functions of the Windows API, but my conclusion is that something is seriously wrong with the functions' behavior, or their documentation.) I was wondering if anybody here experienced with such requirement, and could give me few hints, references, guidance... where to begin? (I've found www.ntfs.com, seems to have NTFS structure information, but I'm afraid I'll need something more to get started...) My intention is to use it under Windows XP. Thanks in advanced, Doori Bar

  • How can I (both) create a row and accessing that row in the same 'Stored Procedure'?

    - by Richard77
    Hello, I'd like to get the value of the id column for an object just after I've created it. But I don't want to run another query for that. My book for beginner (SQL Server 2008 for Dummies) says that there are 2 tables (inserted and deleted) that hold the last row(s) that have been inserted, updated, or deleted. Unfortunately, only Triggers (says the book) can access those tables. But, if I use triggers, they will go off each time I "insert" a row even when I don't need them that functionality. Can I obtain the same effect with a Store Procedure (without having to run a separate query?) This is what I'm trying to do CREATE PROCEDURE myProcedure DECLARE @OrganizationName @ColumnID OUTPUT AS INSERT INTO Organization (OrganizationName) VALUES (@OrganizationName) SET @ColumnID = (// Please, I need Help here ...) Thanks for helping

  • php and mysql user tracking and reporting

    - by inertiahz
    Hi, I currently have a table which consists of user information and lesson id; the table layout looks like: ---------------------------------------------------- |employeeID|numVisits|lessonID1|lessonID2|lessonID3| ---------------------------------------------------- |33388 |2 |1 |0 |3 | and a lessons table which contains the information about the lesson: ------------------------------------------------------ |lessonID |cateogry |title |filepath |numberviews| ------------------------------------------------------ |1 |beginner |lesson |file:// |10 | Within the lessonID fields in the user table is an integer which tracks how many times someone has clicked on a lesson. Now what I am trying to do is in a report I have the top 5 people who have visited the site and would like to then be able to drill down into what lessons they have clicked on. Can anyone help with this? Or would restructuring the way the database is be an easier task? Thanks

  • Can NSUserDefaults be used for pausing the application during a phone call ?

    - by Anil Kumar
    Friends, currently I dont have iphone to test and using Simulator for testing purposes. I am Just curious to know whether an application continues to run even after a phone call.. here i have no option to test this from simulator. If it terminates then how can i pause things.. and continue after a phone call. Is NSUserDefaults can be used for my case. As far I understood NSuserDefaults are used to store data that is required when the App is next time loaded. But here I dont want my App to terminate instead pause until Call ends and continue as uninterrupted later. Please clear me about this. Sorry I am still a beginner so I request for no harsh replies if my question looks stupid. Thanks in Advance

  • Generate matrix with value flags

    - by pagid
    I do have a solution for the following problem but it's quite ugly and it can most likely be done in a much shorter way. Would be great to get your help. My input looks like this: C1 C2 A B B D D C A D and my output should look like this: A B C D 1 1 0 0 0 1 0 1 0 0 1 1 1 0 0 1 My current solution is: index <- unique(unlist(input[,1:2])) output <- matrix(0,nrows=dim(input),ncols=length(index)) for(i in 1:dim(input)) { output[i, input[i,]$C1] <- 1 output[i, input[i,]$C2] <- 1 } Of course 4-5 lines is actually fine - but even as an R beginner this doesn't feel right to use a for loop. Besides that my actual data has much more than two columns, therefore this doesn't look nice in the end. How would I do that in a smarter way? Cheers

  • How Proxy server works with tcp/http connections?

    - by Vivek
    Since I am a beginner in the world of internet/networking, I always mess up with these kinds of doubts in my head while programming ;) .. My doubts are, While working behind a proxy, how my requests and responses work? Means my request headers and data will first reach to Proxy server- then proxy server sends it(same headers and data) to corresponding server. And server responses to it with a response header and body to the proxy server-then proxy server sends it to my computer. Wright? While using websockets we are upgrading our http connection to tcp. At this time what is happening @ Proxy server? Does the proxyserver also upgrades its connection to plain TCP? After opening such TCP connections, does the proxy server able to track/log those socket messsages? And most importantly, Is the proxy server transparent or acting like an original server infront of a client? Thanks for any answers or helpful links in advance.

  • Projects to learn Python

    - by Andrew
    I know this isn't a question about a specific snippet of code or anything, but here goes - I've been messing around with the idea of learning Python since I'm pretty bored with PHP (and web development in general), but I can't think of any projects to help me learn. I've already worked through some of Project Euler with Python, but it's getting old. I know the basics, and I want to write something more fun that will introduce me to new things in Python. Is there a cliche beginner project for Python? (for example, PHP's would be a blog or something similiar) Are there any common Python projects for newcomers, or any uncommon ones that you'd suggest? Any ideas would help.

  • authorization services question cocoa

    - by Marius
    Sorry for being a total beginner in cocoa and for asking the following stupid question, but it's too confusing for me to google it myself or maybe i'm just missing something. I need to run a shellscript with elevated privileges in cocoa. As i understand, "AuthorizationExecuteWithPrivileges" is the correct way to do it. So i've created an application and tried to use some code from one example i found online. The problem is ... if i understand it correctly ... there should be a Security framework in /System/Library/Frameworks that i have to import to the project, but ... it's not there. What am i missing here? Thank you.

  • Is It Worth Using Bitwise Operators In Methods?

    - by user1626141
    I am very new to Java (and programming in general, my previous experience is with ActionScript 2.0 and some simple JavaScript), and I am working my way slowly and methodically through Java: A Beginner's Guide by Herbert Schildt. It is an incredible book. For one thing, I finally understand more-or-less what bitwise operators (which I first encountered in ActionScript 2.0) do, and that they are more efficient than other methods for certain sums. My question is, is it more efficient to use a method that uses, say, a shift right, to perform all your divisions/2 (or divisions/even) for you in a large program with many calculations (in this case, a sprawling RPG), or is it more efficient to simply use standard mathematical operations because the compiler will optimise it all for you? Or, am I asking the wrong question entirely?

  • Jquery/CSS help needed to make fallback for IE and older browsers

    - by matt_50
    Wondering if any of you can help me: I've made a signup modal that uses a CSS transform to switch between two methods of signing up. I've decided to try a 'card flip' type effect. Have a look at this JSfiddle in any browser that supports CSS 3D transforms - click the 'old fashioned way' text to 'flip' the modal (simplified for demo purposes): http://jsfiddle.net/voodoo6/cnTMz/8/ Then take a look in IE8/9 - as the 'back' is taller than the front and IE does;t support 'backface-visibility: hidden;' the reverse can be seen below the front. I've been trying to use JQuery and conditional CSS to 'display:none' the 'back' on load in IE (and older browsers), then add a 'display:block;' class to show it on click, problem is, I'm a JQuery beginner and have been struggling to get it to work! Not even sure if this is the best approach? Can anybody suggest an approach that would get this working in less-capable browsers? Thanks for any advice..

  • Many-to-one relationship in SQLAlchemy

    This is a beginner-level question. I have a catalog of mtypes: mtype_id name 1 'mtype1' 2 'mtype2' [etc] and a catalog of Objects, which must have an associated mtype: obj_id mtype_id name 1 1 'obj1' 2 1 'obj2' 3 2 'obj3' [etc] I am trying to do this in SQLAlchemy by creating the following schemas: mtypes_table = Table('mtypes', metadata, Column('mtype_id', Integer, primary_key=True), Column('name', String(50), nullable=False, unique=True), ) objs_table = Table('objects', metadata, Column('obj_id', Integer, primary_key=True), Column('mtype_id', None, ForeignKey('mtypes.mtype_id')), Column('name', String(50), nullable=False, unique=True), ) mapper(MType, mtypes_table) mapper(MyObject, objs_table, properties={'mtype':Relationship(MType, backref='objs', cascade="all, delete-orphan")} ) When I try to add a simple element like: mtype1 = MType('mtype1') obj1 = MyObject('obj1') obj1.mtype=mtype1 session.add(obj1) I get the error: AttributeError: 'NoneType' object has no attribute 'cascade_iterator' Any ideas?

  • how does teamviewer find my computer even if my comp. behind of the firewall and firewall isn't conf

    - by uzay95
    Did you use teamviewer? (comic question i know... Who doesn't use it?) Do you have any idea how does teamviewer make connection even if i am behind the router, firewall, switch and my local firewall..? I'm trying to imagine a connection that is between remote machinge and my computer. Remote machine is sending the packets (and its header (for instance, destination IP, message body)) to me but it only knows my id number(which is given by my local teamviewer application). And this packets are reaching to my computer even if there is a juniper firewall (and also my windows firewall). What kind a message body is recieving by computer? (of course it is not like xml, text, html, excel :) Do you have any idea? PS. Please share your knowledge like you are explaining to beginner level user.

  • Is it still too early to hop aboard the Python 3 train?

    - by Znarkus
    I'm still a beginner to Python, so I thought I could as well learn the newest iteration of Python. Especially since it is now 3.1 or 3.2 something. But it seems like many mayor modules are still only supported by 2.6. Like the python-mysql module; from what I read on http://mysql-python.blogspot.com/ it seems like 3.x support won't be seen in any near future. Do you use version 3, how do you get around these problems? Should I retreat to 2.6? If not, what should I use to connect to MySQL?
