Weird behaviour of a generator function while converting it to a list

I am trying to get every state of a list while it is being sorted for a visualization. So with bubbleSort algorithm i made a generator function : def bubbleSort(arr): n = len(arr) yield arr # yielding original state for i in range(n): swapped = False for j in range(0, n-i-1): if arr[j] > arr[j+1]:… Read More Weird behaviour of a generator function while converting it to a list

How to break from middle of generator in dart?

How can I break from dart generator based on some condition? fn sync*(…){ yield 1; yield 2; if(someCondition()) //cancel/break the generator yield 3; if(someCondition2()) //cancel/break the generator yield 4; if(someCondition4()) //cancel/break the generator yield 5; } >Solution : Simply return from your generator when you want it to stop generating new values: Iterable<int> fn(bool flag)… Read More How to break from middle of generator in dart?

Print the nth step of a Generator in an easy way

I want to know if there is a better and cleaner way of printing the 3rd step of a generator function. Currently I have written the following code def imparesgen(): n = 0 while n<200: n=n+2 yield n gen = imparesgen() y = 0 for x in gen: y+=1 if y == 3: print(x) This… Read More Print the nth step of a Generator in an easy way

Yield having different behavior when iterated

I have the following function:: def f123(): lista = range(2) print("2: before yields") yield [lista, "A: yield"] print("- after yield A") yield [lista, "B: yield"] print("- after yield B") yield [lista, "C: yield"] print("- after yield C") From what I’ve researched, I can take advantage of my generator by iterating over it or using the… Read More Yield having different behavior when iterated

Is it possible to add the output of a generator when making a list in Python?

Is it possible to make a generator’s output be added into a list creation, without making a nested list in Python? I have tried the following code, but it only gives me a generator object, and not the items. x = 5 expected_list = [3, 0, 0, 0, 0, 0, 3] list = [3, 0… Read More Is it possible to add the output of a generator when making a list in Python?

Generator-based for loop and list-based for loop turns out different output?

Here is the code def func(x): print(x) return x for x in (func(i) for i in range(2)): print(x) print(‘-‘*20) for x in [func(i) for i in range(2)]: print(x) This is the output 0 0 1 1 ——————– 0 1 0 1 Why do they have the different result? i.e, what does python do about (i… Read More Generator-based for loop and list-based for loop turns out different output?

What happens to argument value of first .next() in generator function*

Consider this generator function. Why is the argument of the first call to .next() essentially lost? It will yield and log each of the letter strings but skips "A". Can someone offer an explanation. Please advise on a way that I can access each argument each argument of the .next() method and store it in… Read More What happens to argument value of first .next() in generator function*

Why does generator yield value after loop

I’ve been learning how send method and yield assignment work in generator and met a problem: def gen(): for i in range(5): x = yield i print(x) s = gen() print(next(s)) print(s.send(15)) output: 0 #after print(next(s)) 15 1 so it prints 15 and 1 after print(s.send(15)). It broke my understanding of yield, because I don’t… Read More Why does generator yield value after loop

Is there a danger in letting a generator run for a very long time?

I am designing code to run certain enumeration simulations. I’ll put the code at the end, but I don’t think my question really should concern the details of this program. In principle I think my question could apply just as well to this much more minimal example script: class Generator: def __init__(self, n): self.current =… Read More Is there a danger in letting a generator run for a very long time?

Javascript generator function?

Am I stupid of what does this generator function in Javascript do: function* generator() { let hook, waiting = yield new Promise(resolve => { function* wait() { resolve(yield) } hook = wait(); hook.next(); }); hook.next(waiting); } Source: https://github.com/padlet/async-semaphore >Solution : This one took a couple minutes to process. The resolve(yield) part actually gives the promise… Read More Javascript generator function?
