The brief states "You may assume the parameter is positive", but one of the tests uses 0 as a parameter. Consider changing "positive" to "non-negative".

чтобы найти корень числа в Питоне, нужно возвести его в степень 0.5, например 121**0.5

.sqrt(n); is what I'm using with javascript

'looks like you solved it'

'looks like you solved it'

There is still a typo in that sentence.

I am curious of this one, if it is ok to ask, how would someone here go about getting the roots of a number, possibly on paper the easiest way possible. For example how could I determine that the roots of 121 would in fact be 11?
Edit: Perhpas in python I could use sqrt() for that

ah i see thx

I am not able to submit kata.please help me to resolve issue. there is not button for submit kata

Judging by the fact it hasn't been solved in 4 months and no feedback given to your comment, it seems that nobody really cares about those corner cases. :( Although they render a good portion of solutions plainly wrong.
There's also a really interesting one edge case: (2^26 + 1)^2 - 1. Solutions that test for fraction part of sqrt() to be zero will think it's a perfect square.
