You can use the second argument of iter(), to call a function repeatedly until its return value matches that argument. This would loop forever as 1 will never be equal to 0 (which is the return value of int()): for _ in iter(int, 1): pass If you wanted an infinite loop using numbers that are … Read more
In Kotlin you can use this syntax: for (a in 1..10) print(“$a “) // >>> 1 2 3 4 5 6 7 8 9 10 for (a in 10 downTo 1 step 2) print(“$a “) // >>> 10 8 6 4 2 As for “why was the indexed loop removed” – scroll down for @yole’s … Read more
It’s done like this: class A { public static void main(String[] args) { int n = 13; found: { for (int x : new int[]{2,3,4,5,6,7,8,9,10,11,12}) if (n % x == 0) { System.out.println(“” + n + ” equals ” + x + “*” + (n/x)); break found; } System.out.println(“” + n + ” is a … Read more
You should put your loops inside a function and then return: def myfunc(): for i in range(1, 1001): for i2 in range(i, 1001): for i3 in range(i2, 1001): if i*i + i2*i2 == i3*i3 and i + i2 + i3 == 1000: print i*i2*i3 return # Exit the function (and stop all of the loops) … Read more
Using a labeled break: mainloop: for(){ for(){ if (some condition){ break mainloop; } } } Also See “loop:” in Java code. What is this, and why does it compile? Documentation
This is just meant to be an addition to jonas w’s solutions. If you need the key of the current value: const object = {a:2, b:4, c:6, d:8}; for (const [index, [key, value]] of Object.entries(Object.entries(object))) { console.log(`${index}: ${key} = ${value}`); } Object.entries(object).forEach(([key, value], index) => { console.log(`${index}: ${key} = ${value}`); }); Of course, you can … Read more
Try to do it like this: #set($start = 0) #set($end = 4) #set($range = [$start..$end]) #foreach($i in $range) doSomething #end The code has not been tested, but it should work like this.
C-style for loop has been deprecated in Swift 3. You can continue using it for a while, but they will certainly disappear in the future. You can rewrite your loop to Swift’s style: for i in 0..<len { let length = UInt32 (letters.length) let rand = arc4random_uniform(length) randomString.appendFormat(“%C”, letters.characterAtIndex(Int(rand))) } Since you don’t use i … Read more
I think the documentation referenced in Mike’s answer below is extremely misleading. The order of For Each is defined by the collection it’s called (i.e. its implementation of IEnumerable/IEnumerable<T>), but that’s not the same as saying it shouldn’t be used when the order is important. Many collections (such as arrays, List<T> etc) always go in … Read more
