코드로 우주평화

This Kata is intended as a small challenge for my students All Star Code Challenge #18 Create a function that accepts 2 string arguments and returns an integer of the count of occurrences the 2nd argument is found in the first one. If no occurrences can be found, a count of 0 should be returned. ("Hello", "o") ==> 1 ("Hello", "l") ==> 2 ("", "z") ==> 0 Notes: The first argument can be an empty s..

Complete the square sum function so that it squares each number passed into it and then sums the results together. For example, for [1, 2, 2] it should return 9 because 1^2 + 2^2 + 2^2 = 9. Solution: def square_sum(numbers): square = lambda x:(x**2+x**2)//2 return sum(square(number) for number in numbers)

일상 이번 주에는 특별한 무언가가 있진 않았다. 새로운 프로젝트를 들어갔고 수요일에는 정기회의가 있었다. 회의가 끝나고 저녁에는 동료들과 간단히 치맥을 했다. 원래는 옥상에 돗자리를 펴고 즐기려 했지만 갑자기 날씨가 추워지는 바람에 그러지는 못했다. 그래도 동료들과 함께 마시고 떠드는 게 좋더라. 이런 자리가 종종 있었으면 좋겠다고 생각했다. 운동 매일 조금이라도 운동을 하고 있다. 가장 베스트는 출근 전 헬스장을 가는 것인데, 이번 주는 대체로 지켜진 편이었다. 그런데 요즘 드는 생각은 아침에 헬스장을 가는 것이 꽤나 피곤하다는 것이다. 우선 헬스장을 들렀다 회사를 출근해야 하므로 안 들고 다녀도 될 몇 가지 물품을 들고 다녀야 한다. 그리고 출근을 하면 10시쯤이 되는데 나는 더 일찍 출근하기를 원한..

Given a string, you have to return a string in which each character (case-sensitive) is repeated once. Examples (Input -> Output): * "String" -> "SSttrriinngg" * "Hello World" -> "HHeelllloo WWoorrlldd" * "1234!_ " -> "11223344!!__ " Good Luck! Solution: def double_char(s: str) -> str: return "".join((lambda x: x+x)(i) for i in s)

Write a function that returns the total surface area and volume of a box as an array: [area, volume] Solution: def get_size(w,h,d): wh = w*h*2 hd = h*d*2 wd = w*d*2 return [wh+hd+wd, w*h*d]

Kids drink toddy. Teens drink coke. Young adults drink beer. Adults drink whisky. Make a function that receive age, and return what they drink. Rules: Children under 14 old. Teens under 18 old. Young under 21 old. Adults have 21 or more. Examples: (Input --> Output) 13 --> "drink toddy" 17 --> "drink coke" 18 --> "drink beer" 20 --> "drink beer" 30 --> "drink whisky" Solution: DRINKS = { "Childr..

Bob needs a fast way to calculate the volume of a cuboid with three values: the length, width and height of the cuboid. Write a function to help Bob with this calculation. Solution: from typing import List, Callable def get_multiply(args: List[int], result:int = 1) -> int: for i in args: result *= i return result def get_volume_of_cuboid(length: int, width: int, height: int, func: Callable = get..

Write a function that takes a list of strings as an argument and returns a filtered list containing the same elements but with the 'geese' removed. The geese are any strings in the following array, which is pre-populated in your solution: ["African", "Roman Tufted", "Toulouse", "Pilgrim", "Steinbacher"] For example, if this array were passed as an argument: ["Mallard", "Hook Bill", "African", "C..

Palindrome strings A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. This includes capital letters, punctuation, and word dividers. Implement a function that checks if something is a palindrome. If the input is a number, convert it to string first. Examples(Input ==> Output) "anna" ==> true "walter" ==> false 12321 ==> true 123456 =..

Alex just got a new hula hoop, he loves it but feels discouraged because his little brother is better than him Write a program where Alex can input (n) how many times the hoop goes round and it will return him an encouraging message :) If Alex gets 10 or more hoops, return the string "Great, now move on to tricks". If he doesn't get 10 hoops, return the string "Keep at it until you get it". Solu..
