问题 I'm making a small Python program, which calls the webbrowser module to open a URL. Opening the URL works wonderfully. My problem is that once this line of code is reached, the problem is unresponsive. How do I get the program to proceed past this line of code and continue to execute? Below the problematic line is the problematic line, in context: if viewinbrowser == "y": print "I can definitely do that. Loading URL now!" webbrowser.open_new(url) print "Exiting..." sys.exit() The program does

问题 I'm new here and to C++. I've had some experience in python, and found "if a in b" really easy, and I'm wondering if there's an equivalent in C++. Background I've been trying to make a list of strings and check if an input is in that list. The reason I want to do this is because I want to only use a function if the input will actually do something in that function. (Change int x and y coordinates in this case) Question string myinput; string mylist[]={"a", "b", "c"}; cin>>myinput; //if

问题 In the following code i need the value of varArray[i] for executing the if-else statements but the if-else statements are to be executed only once. If i place the if-else statements outside the for loop the if-else statements do execute correctly. When i place the if-else statement inside the for loop the if-else statements get executed multiple times. for (int i=0;i<varArray.length;i++) { varArray[i]= rand.nextInt(1999)-1000; System.out.println(varArray[i]); if(d==varArray[i]) { System.out

问题 I am getting value from a text field. I have one if and several else if statement. The problem the last else if doesn't execute even if the condition is true. If I change the last else if to if it executes and gives alert. When I change that back to else if the statement doesn't execute. The else if before that is fine as it's firing/executing on a particular condition. function Valcheck() { var txtVal = document.getElementById("sometextField").value; if(txtVal =="%") { alert("% is only

问题 I want to insert values in a column based on the following conditions. Name of the column to be inserted is project_renewal. If decimal exists in project_code, insert the numbers after decimals. SELECT substring_index(project_code, '.', -1) FROM projects where project_code like '%.%' If no decimal, insert 0. SELECT project_code FROM projects where project_code not like '%.%' Order of insert must be the same as the order of reading values from project_code. 回答1: INSERT IGNORE INTO outtable
