The purpose of this kata is to work out just how many bottles of duty free whiskey you would have to buy such that the saving over the normal high street price would effectively cover the cost of your holiday. You will be given the high street price (normPrice), the duty free discount (discount) and the cost of the holiday. For example, if a bottle cost £10 normally and the discount in duty free..

Your task is to create a function that does four basic mathematical operations. The function should take three arguments - operation(string/char), value1(number), value2(number). The function should return result of numbers after applying the chosen operation. Examples(Operator, value1, value2) --> output ('+', 4, 7) --> 11 ('-', 15, 18) --> -3 ('*', 5, 5) --> 25 ('/', 49, 7) --> 7 Solution: def..

Tenacity 란? 보통 에러나 예외처리에 의해 런타임이 종료될 때가 있다. Tenacity는 런타임 종료없이 함수를 다시 실행시켜주는 Python 라이브러리이다. 사용법 1. Tenacity 설치 pip install tenacity 2. Tenacity 라이브러리 가져오기 및 함수 작성 import tenacity def throw_error(): print("running...") raise ValueError("Errors make me stronger") if __name__ == "__main__": throw_error() 이대로 스크립트를 실행해보면 우리가 의도한대로 에러가 발생하며 곧바로 스크립트가 종료된다. running...

Write a function that takes an array of numbers and returns the sum of the numbers. The numbers can be negative or non-integer. If the array does not contain any numbers then you should return 0. Examples Input: [1, 5.2, 4, 0, -1] Output: 9.2 Input: [] Output: 0 Input: [-2.398] Output: -2.398 Assumptions You can assume that you are only given numbers. You cannot assume the size of the array. You..

Wolves have been reintroduced to Great Britain. You are a sheep farmer, and are now plagued by wolves which pretend to be sheep. Fortunately, you are good at spotting them. Warn the sheep in front of the wolf that it is about to be eaten. Remember that you are standing at the front of the queue which is at the end of the array: [sheep, sheep, sheep, sheep, sheep, wolf, sheep, sheep] (YOU ARE HER..

Your task is to find the first element of an array that is not consecutive. By not consecutive we mean not exactly 1 larger than the previous element of the array. E.g. If we have an array [1,2,3,4,6,7,8] then 1 then 2 then 3 then 4 are all consecutive but 6 is not, so that's the first non-consecutive number. If the whole array is consecutive then return null2. The array will always have at leas..

This kata is from check py.checkio.org You are given an array with positive numbers and a non-negative 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 3^2 == 9; array = [1, 2, 3] ..

Given a string, capitalize the letters that occupy even indexes and odd indexes separately, and return as shown below. Index 0 will be considered even. For example, capitalize("abcdef") = ['AbCdEf', 'aBcDeF']. See test cases for more examples. The input will be a lowercase string with no spaces. Good luck! Solution: def capitalize(s): return [''.join(v.lower() if i%2==1 else v.upper() for i, v i..

This program tests the life of an evaporator containing a gas. We know the content of the evaporator (content in ml), the percentage of foam or gas lost every day (evap_per_day) and the threshold (threshold) in percentage beyond which the evaporator is no longer useful. All numbers are strictly positive. The program reports the nth day (as an integer) on which the evaporator will be out of use. ..

Given a 2D ( nested ) list ( array, vector, .. ) of size m * n, your task is to find the sum of the minimum values in each row. For Example: [ [ 1, 2, 3, 4, 5 ] # minimum value of row is 1 , [ 5, 6, 7, 8, 9 ] # minimum value of row is 5 , [ 20, 21, 34, 56, 100 ] # minimum value of row is 20 ] So the function should return 26 because the sum of the minimums is 1 + 5 + 20 = 26. Note: You will alwa..
