All functions except repeatntimes are ok.

Try to test the following call and think about why it gives such result repeatntimes(squares([1, 2, 3]), 2)

[romanovamar]

Ok, I get why it happens. I changed it a bit.

[YakutovDmitriy]

Lets executethe following code:

for elem in repeatntimes(itertools.count(), 2):
    if elem % (10 ** 6) == 0:
        print(elem)

Your implementation gets MemoryError after about 68 million operations. This is because you spend infinite memory if your input is infinite. Try to avoid it. itertools docs can help you

[romanovamar]

Ok, then I just use tee.

[YakutovDmitriy]

Almost ok. But I can't run your function. Please fix it

[romanovamar]

Done, I guess

[YakutovDmitriy]

Good :)
