i many examples in internet there same: public class test extends thread { public synchronized void run() { (int = 0; <= 10; i++) { system.out.println("i::"+i); } } public static void main(string[] args) { test obj = new test(); thread t1 = new thread(obj); thread t2 = new thread(obj); thread t3 = new thread(obj); t1.start(); t2.start(); t3.start(); } } so why call same task (in run() method) 3 times different threads? e.g. if want upload file, why call 3 times? assume if need multithreading then: thread t1 task1, e.g.: - update database info thread t2 task2, e.g.: - upload file server thread t3 task3, e.g.: - bring message user is there example work described above. you can create multiple threads code given below start thread , don't need call multiple times same method. can see, once started, 3 child threads share cpu. notice call slee

python - How to fix this? RuntimeError: dictionary changed size during iteration -

when added item dictionary in a function, it's giving error: inv = { "rope": 1, "torch": 6, "gold coin": 42, "dagger": 1, "arrow": 12 } dragonloot = ['gold coin', 'dagger', 'gold coin', 'gold coin', 'ruby'] def addinventory(invloop, lst): item in lst: k,v in invloop.items(): if item == k: v += 1 else: invloop[item] = 1 return(invloop) inv = addinventory(inv, dragonloot) indeed should not add items inventory while looping on it. what's more, don't need inner loop, because advantage of dictionary have direct access via keys: can test whether has key or not in operator. so instead: def addinventory(invloop, lst): item in lst: if item in invloop: invloop[item] += 1 else: invloop[item] = 1 return(invloop)
