infinite-loop

问题 I'm very new to Python. I made a math program that keeps generating a new math problem every time you get the last one right. however I don't know how to exit/break the while True loop and switch from addition to subtraction. import random while True: question = input("press 1 for addition, press 2 for subtraction.") if question == "1": print("Try your skill at these problems.") number1 = random.randint(0, 9) number2 = random.randint(0, 9) while True: print(number1, "+", number2, "=") number3

问题 I have this htaccess file: RewriteEngine On RewriteCond %{HTTP_HOST} =test.example.com [NC] RewriteRule ^((?!test/).*)$ test/$1 [L,NC] And a completely identical copy of the same file in the "test" directory. So, of course, this leads to an infinite loop when the first file pass you to the second file running the rules again. I have tried add the rule RewriteCond %{REQUEST_URI} !^test [L,NC] in hope that REQUEST_URI stood for the real path and not the new "alias". However, it didn't worked.

问题 Hi I have some simple code here. https://pastebin.com/97uuqKQD I would simply like to add something like this, to the button function, so while the root window is open the datetime and exrates are constantly regotten from the xe website and displayed. amount = '1' def continuousUpdate(): while amount == '0': results() def results(): #Get xe data put to labels etc here btnConvert = tk.Button(root, text="Get Exchange Rates",command=continuousUpdate).place(x=5,y=102) Once I input the two exrates

问题 Note - this question is a follow-up to Find infinite loop in progress in a modal form?. Once I learned how to debug that issue, it raised this question. I have a rare condition which causes my WPF app to consume maximum CPU and the GUI become unresponsive. Based on the high CPU usage it obviously is running (not blocked externally) Using Process Explorer I can see that in the stack trace nearly all the time is being spent inside functions in wpfgfx_v0400.dll , mostly in functions Utility

问题 I am trying to make updates to two linked TextBox es. I disable events in one and then send keystrokes using eg SendKeys::Send("A"); having first given it focus: texBox2->Focus(); texBox2->KeyDown -= gcnew KeyEventHandler(this, &Form1::texBox2_KeyDown); SendKeys::Send("A"); texBox2->KeyDown += gcnew KeyEventHandler(this, &Form1::texBox2_KeyDown); It almost works but goes totally mental instead repeating the character (I daren't look to check which exact key because I'm frantically

问题 I've just started learning C++. I am currently using Bloodshed Dev C++. dI'm creating a very basic and simple Rock Paper and Scissors Game. Everything in the program is working correctly except for the exit loop. Here is my code: /* FILE INFO File Name: Chapter 3 - Project 1.cpp Author: Richard P. P#: --------- Assignment: Chapter 3 Project 1 */ #include <iostream> using namespace std; int main() { char Player1_choice; char Player2_choice; char keep_going; cout << "Welcome to Rock, Paper,

问题 I'm building a program that fills a hollow cube with many small cubes. Then, makes a connected path through random cubes. The path is found step by step by looking at the direct neighbors of each cube and select anyone of them as the next step. To illustrate, The following picture shows the path that consists of cubes (red cubes), To build the path I started form some cube, colored it with red, found its neighbor cubes (6 neighbors because we have 6 faces), selected any of them randomly,

问题 I'm trying to write a simple hand-rolled function to flatten a nested array. My code works fine as a switch statement, but not when I'm recursively calling it within a "for i in 0..arr.count" loop. I look at each element in the passed in array and say "if this is an array, call the function and pass this in, else append to the output array". func flatten (input: [Any]) -> [Any] { var outputArray = [Any] () for i in 0..<input.count { let data = input[i]; (data is Array) ? outputArray +=
