Description: This is a spin off of my first kata. You are given a string containing a sequence of character sequences separated by commas. Write a function which returns a new string containing the same character sequences except the first and the last ones but this time separated by spaces. If the input string is empty or the removal of the first and last items would cause the resulting string ..

Description: Our football team finished the championship. The result of each match look like "x:y". Results of all matches are recorded in the collection. For example: ["3:1", "2:2", "0:1", ...] Write a function that takes such collection and counts the points of our team in the championship. Rules for counting points for each match: if x > y: 3 points if x < y: 0 point if x = y: 1 point Notes: ..

Description: Given an array of integers, return a new array with each value doubled. For example: [1, 2, 3] --> [2, 4, 6] Solution: 1. Get the elements out of the array. 2. Multiply the element by 2 and put it back into the array. 3. Return an array. def maps(a): return list(map(lambda x: x * 2, a)) The lambda function is an anonymous function and is suitable for simple calculations.

예제 코드 # setup.cfg [flake8] exclude = .git max-line-length = 88 [black] line-length = 88 flake8 과 black 에 ‘line-length’설정 값이 중복되는 것이 아니냐는 의견이 있었습니다. 우선 결론부터 말씀드리자면 둘다 있어야 한다고 생각합니다. 그 이유는 어느 한쪽을 생략한 경우, 생략한 쪽은 기본값을 채택하여 개발자가 원하는대로 작동하지 않기 때문입니다. 예를들어 위에 문서에서 flake8의 ‘max-line-length = 88’ 를 생략하는 경우 # 코드 수정 [flake8] exclude = .git # max-line-length = 88 black은 88자를 통과시키지만 flake8은 기본값인 79자를 기준으로 검사..

Description: Write a function which calculates the average of the numbers in a given list. Note: Empty arrays should return 0. Solution: 1. If 'numbers' is an empty array, 0 is returned. 2. If it is not empty, the average value is returned. import statistics def find_average(numbers): return statistics.mean(numbers) if numbers else 0 statistics.mean() is a Python built-in library that calculates..

pre-commit 적용하기 해당 글은 깃헙 레포지토리에서도 확인가능합니다. 깃헙 링크 pre-commit란? 커밋 메시지를 작성하기 전에 호출이 되는 명령어입니다. 커밋이 되기 전 문법 오류나 스타일, 정렬, 타입 오류 등을 체크할 때 사용합니다. 개발자의 기호에 따라 선택하고 커스텀까지 할 수 있습니다. pre-commit 적용 순서 1. git init 2. pip install pre-commit 3. pre-commit install >>> pre-commit installed at .git/hooks/pre-commit 4. pre-commit run >>> An error has occurred: InvalidConfigError: =====> .pre-commit-config.yaml is..

Description: You get an array of arrays. If you sort the arrays by their length, you will see, that their length-values are consecutive. But one array is missing! You have to write a method, that return the length of the missing array. Example: [[1, 2], [4, 5, 1, 1], [1], [5, 6, 7, 8, 9]] --> 3 If the array of arrays is null/nil or empty, the method should return 0. When an array in the array is..

Description: Input : an array of integers. Output : this array, but sorted in such a way that there are two wings: the left wing with numbers decreasing, the right wing with numbers increasing. the two wings have the same length. If the length of the array is odd the wings are around the bottom, if the length is even the bottom is considered to be part of the right wing. each integer l of the le..

Description: Complete the code which should return true if the given object is a single ASCII letter (lower or upper case), false otherwise. Solution: 1. Get the ASCII code of the argument. 2. Check whether the obtained ASCII code corresponds to the alphabet. 3. True if true, false otherwise. def is_letter(s): ascii_num = len(s) == 1 and ord(s) return (ascii_num >= 65 and ascii_num = 97 and asci..
