A couple of changes mean that only an R or r will roll. Any other character will quit import random while True: print(‘Your score so far is {}.’.format(myScore)) print(“Would you like to roll or quit?”) ans = input(“Roll…”) if ans.lower() == ‘r’: R = np.random.randint(1, 8) print(“You rolled a {}.”.format(R)) myScore = R + myScore … Read more
Good lord no. Sometimes there is a possibility that something can occur in the loop that satisfies the overall requirement, without satisfying the logical loop condition. In that case, break is used, to stop you cycling around a loop pointlessly. Example String item; for(int x = 0; x < 10; x++) { // Linear search. … Read more
You’re currently making a command-line application which reads stuff from standard input and prints stuff to standard output. How buttons presses are handled depends entirely on the terminal in which your are running your program, and most terminals won’t send anything to your application’s stdin when escape is pressed. If you want to catch key … Read more
break; is what you need to break out of any looping statement like for, while or do-while. In your case, its going to be like this:- for(int x = 10; x < 20; x++) { // The below condition can be present before or after your sysouts, depending on your needs. if(x == 15){ break; … Read more

if is not a loop structure, so you cannot “break out of it”. You can, however, break out of the foreach by simply calling break. In your example it has the desired effect: $device = “wanted”; foreach($equipxml as $equip) { $current_device = $equip->xpath(“name”); if ( $current_device[0] == $device ) { // found a match in … Read more
Use break: while (true) { …. if (obj == null) { break; } …. } However, if your code looks exactly like you have specified you can use a normal while loop and change the condition to obj != null: while (obj != null) { …. }
