Complete the function that calculates the area of the red square, when the length of the circular arc A is given as the input. Return the result rounded to two decimals. Note: use the π value provided in your language (Math::PI, M_PI, math.pi, etc) Solution: def square_area(A): import math return round((A/math.pi*4/2)**2, 2)

Create a function that converts US dollars (USD) to Chinese Yuan (CNY) . The input is the amount of USD as an integer, and the output should be a string that states the amount of Yuan followed by 'Chinese Yuan' Examples (Input -> Output) 15 -> '101.25 Chinese Yuan' 465 -> '3138.75 Chinese Yuan' The conversion rate you should use is 6.75 CNY for every 1 USD. All numbers should be represented as a..

Write a function to split a string and convert it into an array of words. Examples (Input ==> Output): "Robin Singh" ==> ["Robin", "Singh"] "I love arrays they are my favorite" ==> ["I", "love", "arrays", "they", "are", "my", "favorite"] Solution: from typing import List def string_to_array(s: str) -> List[str]: return split(s) def split(s: str, c: str = " ") -> List[str]: list, ci = [], 0 for i..

Write a function that checks if a given string (case insensitive) is a palindrome. Solution: def is_palindrome(s): target = s.lower() for i in range(len(target)//2): if target[i] != target[-i-1]: return False return True def is_palindrome(s): s = s.lower() return s == s[::-1]

Given an array of integers your solution should find the smallest integer. For example: Given [34, 15, 88, 2] your solution will return 2 Given [34, -345, -1, 100] your solution will return -345 You can assume, for the purpose of this kata, that the supplied array will not be empty. Solution: # 1 def find_smallest_int(arr): return sorted(arr, reverse=True).pop() # 2 def find_smallest_int(arr): r..

외부 API로부터 받은 응답 값이 정상이 아니라면 우리는 응답이 잘못되었음을 어떻게 확인할 수 있을까? 매번 요청 때마다 응답의 상태 코드를 일일이 체크하고 핸들링해야 할까? python의 requests 라이브러리에서는 이러한 번거로움을 줄이기 위해 raise_for_status() 메서드가 있다. raise_for_status()는 응답의 상태 코드가 400 이상인 경우 HTTPError를 raise 한다. raise 를 통해 외부 모듈과의 통신상태를 확인하고 쉽게 핸들링을 할 수 있다. 사용법은 간단하다. requests 요청으로 응답받은 res 객체로부터 raise_for_status() 메서드를 호출하면 된다. url = "" res = requests.post(url) res.raise_for..

Create a method that accepts a list and an item, and returns true if the item belongs to the list, otherwise false. Solution: from typing import List def include(arr: List[int], item: int) -> bool: return bool(arr.count(item))

Your goal is to return multiplication table for number that is always an integer from 1 to 10. For example, a multiplication table (string) for number == 5 looks like below: 1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25 6 * 5 = 30 7 * 5 = 35 8 * 5 = 40 9 * 5 = 45 10 * 5 = 50 P. S. You can use \n in string to jump to the next line. Note: newlines should be added between rows, but there sh..

You are required to create a simple calculator that returns the result of addition, subtraction, multiplication or division of two numbers. Your function will accept three arguments: The first and second argument should be numbers. The third argument should represent a sign indicating the operation to perform on these two numbers. if the variables are not numbers or the sign does not belong to t..

In this simple exercise, you will build a program that takes a value, integer , and returns a list of its multiples up to another value, limit . If limit is a multiple of integer, it should be included as well. There will only ever be positive integers passed into the function, not consisting of 0. The limit will always be higher than the base. For example, if the parameters passed are (2, 6), t..
