You are given an array of integers. You should find the sum of the integers with even indexes (0th, 2nd, 4th...). Then multiply this summed number and the final element of the array together. Don't forget that the first element has an index of 0. For an empty array, the result will always be 0 (zero). Input: A list of integers. Output: The number as an integer. Example: checkio([0, 1, 2, 3, 4, 5..

"Fizz buzz" is a word game we will use to teach the robots about division. Let's learn computers. You should write a function that will receive a positive integer and return: "Fizz Buzz" if the number is divisible by 3 and by 5; "Fizz" if the number is divisible by 3; "Buzz" if the number is divisible by 5; The number as a string for other cases. Input: A number as an integer. Output: The answer..

"Where does a wise man hide a leaf? In the forest. But what does he do if there is no forest? ... He grows a forest to hide it in." -- Gilbert Keith Chesterton Ever tried to send a secret message to someone without using the postal service? You could use newspapers to tell your secret. Even if someone finds your message, it's easy to brush them off as paranoid and as a conspiracy theorist. One o..

You are given a positive integer. Your function should calculate the product of the digits excluding any zeroes. For example: The number given is 123405. The result will be 1*2*3*4*5=120 (don't forget to exclude zeroes). Input: A positive integer. Output: The product of the digits as an integer. Example: checkio(123405) == 120 checkio(999) == 729 checkio(1000) == 1 checkio(1111) == 1 * 0을 빼고 각 자..

You are given an array with positive numbers and a number N. You should find the N-th power of the element in the array with the index N. If N is outside of the array, then return -1. Don't forget that the first element has the index 0. Let's look at a few examples: - array = [1, 2, 3, 4] and N = 2, then the result is 32 == 9; - array = [1, 2, 3] and N = 3, but N is outside of the array, so the ..

대부분의 기계 학습 데이터는 최종 모델을 만드는데 있어서 이상적인 형식이 아니다. 범주형 변수를 조작하거나 스케일링 및 정규화와 같은 많은 데이터 변환이 수행되어야 한다. Scikit-Learn은 전처리 기능에 일반적으로 사용되는 대부분의 기능을 내장하고 있다. 그러나 일반적인 기계 학습 워크플로우에서는 이러한 모든 변환을 두 번 이상 적용해야 한다. 모델을 교육할 때 한 번 그리고 예측하고자 하는 모든 새로운 데이터에 대해 다시 한 번하기 때문이다. 물론 재사용하는 기능을 쓸 수 있지만 먼저 실행하고 나서 모델을 따로 불러야 할 것이다. Scikit-Learn pipeline은 이 과정을 단순화하는 도구로써 다음과 같은 몇 가지 주요 이점이 있다. 파이프라인을 사용하면 데이터 사전 처리 및 분류의 모든..

our mission here is to create a function that gets a tuple and returns a tuple with 3 elements - the first, third and second to the last for the given array. Input: A tuple, at least 3 elements long. Output: A tuple. Example: easy_unpack((1, 2, 3, 4, 5, 6, 7, 9)) == (1, 3, 7) easy_unpack((1, 1, 1, 1)) == (1, 1, 1) easy_unpack((6, 3, 7)) == (6, 7, 3) * 튜플에서 첫번째, 세번째 그리고 뒤에서 두번째 값을 output - 풀이 def..

n this mission you should write a function that introduces a person with the given parameter's attributes. Input: Two arguments. String and positive integer. Output: String. Example: say_hi("Alex", 32) == "Hi. My name is Alex and I'm 32 years old" say_hi("Frank", 68) == "Hi. My name is Frank and I'm 68 years old" - 풀이 def say_hi(name: str, age: int): s_age = str(age) return "Hi. My name is "+ na..
