Not much to go on here, but after a for statement such as this, you need a line after this and 4 spaces before your next statement. A lot of programming languages use { and } to signify the start and stop of a block of code, Python uses indentation (4 spaces) to do this. … Read more
I feel bad writing this answer, but hopefully this will prevent all other answers and close the ticket. private static int ToPercentage(double d) { return (int)(d*100); } EDIT: Thanks Devid for the suggestion 🙂 TIL how to make an answer a community wiki post! 2 solved Converting decimal percentage to int
Forgot to add a reference to the ctp5 dll to my schemas project, it was using System.Data.Linq.Mapping instead. solved EF4 CTP5 Code First approach ignores Table attributes
There are a whole bunch of reasons why this is the wrong approach. First, innerHTML returns a string containing, not only the text content of an element, but also any nested HTML elements as well. If it’s just the text you want, use textContent. Next, by having the user input the actual math operator they … Read more
Use defaultdict() to collect parameters per url path: from collections import defaultdict from urllib import quote from urlparse import parse_qsl, urlparse urls = defaultdict(list) with open(‘links.txt’) as f: for url in f: parsed_url = urlparse(url.strip()) params = parse_qsl(parsed_url.query, keep_blank_values=True) for key, value in params: urls[parsed_url.path].append(“%s=%s” % (key, quote(value))) # printing results for url, params in … Read more
Integer.parseInt couldn’t do the job, unless you were happy to lose data. Think about what you’re asking for here. Try Long.parseLong(String) or new BigInteger(String) for really big integers. solved In Java, how do I parse a string bigger than int size
To make apps (mobile apps, I think you mean) for different OS’s(I think you mean the different OS’s on each phone),(assumption: that you’re coding it from scratch) you learn a programming language first, then proceed to learn how to make apps for a particular OS. Typically, you purchase a book (look online for good recommendations) … Read more
I was able to edit a JavaScript file using regex. my code is below: function updateFile(filename, replacements) { return new Promise(function(resolve) { fs.readFile(filename, ‘utf-8’, function(err, data) { var regex, replaceStr; if (err) { throw (err); } else { regex = new RegExp(“(\\” + ‘let’ + “\\s* ]*” + replacements[0].rule + “\\s*=\\s*)([^\\n;}]+)([\\s*;}])”); replaceStr = “$1” + … Read more
Change the 9 to a 10: if temp2[4] == ‘-‘ and temp2[10] != ‘-‘: temp3 = temp2[:10] + ‘-‘ + temp2[10:] When you call a string its str[from:to], so temp2[:9] is equivalent to temp2[0:9] and it would only return the characters from 0-9 instead of the required 0-10 0 solved Python String unwanted overwrite
I think the recommended answer would be something along these lines: hello=”Hello” world=’World’ hello_world=hello + ‘ ‘ + world print=hello_world Run output: Hello World solved What’s wrong here? (concatenation) in Python
Every widget constructor should never block the main message loop! The main message loop looks usually like this: int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w(nullptr); w.show(); int r = a.exec(); return r } In your case your MainWindow ctor never returns, so w.show() is never called and a.exec() (main messgae loop) … Read more
There is probably not a significant performance gain in using a C/C++ dll. The C# runs in an environment with a quite efficient JIT compiler, so my guess is that the code performance is limited by a hard disk read speed of approximately 100 MB/s. Of course, if you have an SSD, your mileage may … Read more

To achieve this you could use ggplot. Here an example: require(ggplot2) df <- data.frame(x = c(-2, -1.5, 1, 2, 3), y = c(-1, 0.8, 1, 1, 2), country = c(“SWI”, “FRA”, “US”, “UK”, “NL”), size = c(15,12,20,4,7)) ggplot(df, aes(x = x, y = y)) + geom_point(aes(size = size), pch=1) +geom_text(aes(label=country),hjust=-0.5, vjust=0) + xlim(c(-3,4)) + scale_size_continuous(range … Read more
It depends on your operating system. On Windows the new FileOutputStream(…) will probably fail. On Unix-line systems you will get a new file while the old one continues to be readable. However your copy loop is invalid. available() is not a test for end of stream, and it’s not much use for other purposes either. … Read more
