extraction

I would like to extract the bold text, which is indicating the latest weather psi from this website http://app2.nea.gov.sg/anti-pollution-radiation-protection/air-pollution/psi/psi-readings-over-the-last-24-hours . Does anyone know how to extract using this code below ? Also I needed to extract two values that is infront of the current weather psi to do calculate. Total of three value (latest and previous two values) Example: current value ( bold ) is 5AM : 51, I need also 3AM and 4AM. Does anyone knows and can help me with this ? Thanks in advance ! from pprint import pprint import urllib2

Recently I'm planning to manipulate a stack of images and the goal is to extract a specific subset of slices from there, for example only even or odd or arbitrary indexes, and then save them into another dataset. In DM, there are a number of helpful functions in the Volume menu but unfortunately, they cannot really fullfill what I want to do. I am just wondering whether this idea can be realized via scripting. Many thanks for your help in advance. There are two ways you can go about it, one of them only suitable for data up to 3D and generally slower than the other, but more flexible. As you

I'm following a tutorial to extract video frames. I've read this question , it doesn't work, also queationfrom Open CV Answer , but the solution is for capturing current frame. I have a 120fps video and want to extract all of them. Here's my code #include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/imgproc/imgproc.hpp> #include <iostream> #include <string> #include <sstream> using namespace cv; using namespace std; int c = 0; string int2str(int &); int main(int argc, char **argv) { string s; VideoCapture cap("test.mp4"); // video if (!cap.isOpened()) { cout

Sorry I am not very sure how to state the question title. My problem is like this, I had developed a Java program, and I wish to distribute it to my friends. So I export it to Jar file, but I don't want them to extract the jar file to view the code. Is there anyway to make the program so that nobody can get the source code instead just launch the program. You appear to be confusing the installation application with the executable. And I also think you are confusing a java jar application with a normal .exe. Even then, these are all just bundles of code which can still be decompiled, it's just

I have a .gz file and I need to get the name of files inside it using python. This question is the same as this one The only difference is that my file is .gz not .tar.gz so the tarfile library did not help me here I am using requests library to request a URL. The response is a compressed file. Here is the code I am using to download the file response = requests.get(line.rstrip(), stream=True) if response.status_code == 200: with open(str(base_output_dir)+"/"+str(current_dir)+"/"+str(count)+".gz", 'wb') as out_file: shutil.copyfileobj(response.raw, out_file) del response This code downloads

I'm trying to use it to manipulate data in large txt-files. I have a txt-file with more than 2000 columns, and about a third of these have a title which contains the word 'Net'. I want to extract only these columns and write them to a new txt file. Any suggestion on how I can do that? I have searched around a bit but haven't been able to find something that helps me. Apologies if similar questions have been asked and solved before. EDIT 1: Thank you all! At the moment of writing 3 users have suggested solutions and they all work really well. I honestly didn't think people would answer so I

System.IO.Compression.ZipFile.ExtractToDirectory(zipPath, extractPath); Using ZipFile in C#, I'm trying to extract a file from a known location and it is throwing the following error: System.IO.Exception: Zip entry name ends in directory separator character but contains data I've done some research, ExtractToDirectory is explained in MSDN but couldn't find this error definition. Would you be able to explain why this error is happening?
