"For centuries, left-handers have suffered unfair discrimination in a world designed for right-handers." Santrock, John W. (2008). Motor, Sensory, and Perceptual Development. "Most humans (say 70 percent to 95 percent) are right-handed, a minority (say 5 percent to 30 percent) are left-handed, and an indeterminate number of people are probably best described as ambidextrous." Scientific American..

For the input of your function, you will be given one sentence. You have to return a corrected version, that starts with a capital letter and ends with a period (dot). Pay attention to the fact that not all of the fixes are necessary. If a sentence already ends with a period (dot), then adding another one will be a mistake. Input: A string. Output: A string. Example: correct_sentence("greetings,..

점프 투 파이썬 기초 책 한 권을 다 떼고.. 그럼 이젠 뭐하지 ? 이런 고민 하는 사람들 많을 것이다. 물론 나도 그랬다. 이런 저런 사이트를 뒤져보고 파이썬 문제 은행도 뒤져봤지만 딱히 내가 만족할만 곳을 찾지 못했다. 그때 발견한 CheckIO 사이트. CheckIO는 Python 문제를 게임처럼 풀 수 있는 사이트인데 Java Script도 가능하다. 다음에 시간남으면 java script도 해봐야딩.. 영어라서 한국 사람들에게 안맞을 수도 있지만 영어 공부도 하면서 파이썬 문제도 풀수 있어서 나한테는 딱 맞는 곳인듯. 그리고 영어가 별로 어려운 단어도 없고 나에겐 파파고가 있으니까 ! CheckIO 추천합니다. 저랑 같이 풀어봐욥 https://py.checkio.org/ CheckiO - co..

You are given the current stock prices. You have to find out which stocks cost more. Input: The dictionary where the market identifier code is a key and the value is a stock price. Output: The market identifier code (ticker symbol) as a string. Example: best_stock({"CAC": 10.0, "ATX": 390.2, "WIG": 1.2}) == "ATX" best_stock({"CAC": 91.1, "ATX": 1.01, "TASI": 120.9}) == "TASI" * 딕셔너리 형태로 값 비교해서 제..

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 ..

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..
