| I don't know how to start solving this mission | ||
| </div> | ||
| <div class="answer"> | ||
| The idea is to find the correspondence between one hour and one degree, between one minute and one degree. | ||
| After that, just calculate the angle of inclination, taking into account that 18:00 is 180 degrees, and 6:00 is 0 degrees. | ||

| <div class="answer"> | ||
| It will be helpful to read a little information about: | ||
| <a href='https://docs.python.org/3.10/library/stdtypes.html'>str.split()</a> | ||
| (<a href='https://www.w3schools.com/python/ref_string_split.asp'>example</a> ), | ||
| <a href='https://docs.python.org/3.10/library/functions.html?#map'>map()</a> | ||
| (<a href='https://www.w3schools.com/python/ref_func_map.asp'>example</a> ), and | ||

| </div> | ||
| </div> | ||
| <div class="question-answer"> | ||
| <div class="question"> | ||
| Need help! | ||
| </div> | ||
| <div class="answer"> | ||
| Let's start with the preparation of our input line before calculation. We will transfer to the variables "h" | ||
| and "m" the values of hours and minutes, respectively, already converted to the integer data type using | ||
| the map() and int() functions. The form of recording through coma "h, m = map(int, ...)" is equivalent | ||
| to the next form "h = int(...)" and "m = int(...)". We use the int() function to each item of the split | ||
| line using the separator ":". | ||
| <pre class="brush: python"> | ||
| time = "07:00" | ||
| h, m = map(int, time.split(':')) | ||
| print(h) | ||
| print(m) | ||
|
|
||
| # Output: | ||
| # 7 | ||
| # 0 | ||

| <div class="question-answer"> | ||
| <div class="question"> | ||
| I don't know what to do anymore. I need a little hint. | ||
| </div> | ||
| <div class="answer"> | ||
| Let's move on to the calculation formula. Hours and minutes correlate to degrees as follows: 6 hours = 90 | ||
| degrees, so 90/6 = 15, 1 hour is 15 degrees; 6 hours = 360 minutes = 90 degrees, so 90/360 = 0.25, 1 minute | ||
| is 0.25 degrees. 6:00 = 0 degrees, then when calculating, we need to take it into | ||
| account by taking away 90 from the result. The formula will be as follows. | ||
| <pre class="brush: python"> | ||
| time = "07:00" | ||
| h, m = map(int, time.split(':')) | ||
| angle = 15 * h + m * 0.25 - 90 | ||
| </pre> | ||

| </div> | ||
| <div class="question-answer"> | ||
| <div class="question"> | ||
| Nothing works. SOS | ||
| </div> | ||
| <div class="answer"> | ||
| You have to write the condition of if you will return either the result, if the sun is visible, | ||
| or the phrase "I don See the sun!", If the sun is not visible. We use the ternary operator for this purpose. | ||
| <pre class="brush: python"> | ||
| time = "07:00" | ||
| h, m = map(int, time.split(':')) | ||
| angle = 15 * h + m * 0.25 - 90 | ||
| print(angle) if 0 <= angle <= 180 else print("I don't see the sun!") | ||
|
|
||
| # Output: | ||
| # 15.0 | ||

| <div class="question-answer"> | ||
| <div class="question"> | ||
| I don't want to give up, help! | ||
| </div> | ||
| <div class="answer"> | ||
| All you have to do is wrap your code in a function, and add our if condition to the return expression. | ||
| <pre class="brush: python"> | ||
| def sun_angle(time: str) -> Union[float, str]: | ||
| h, m = map(int, time.split(':')) | ||
| angle = 15 * h + m * 0.25 - 90 | ||
| return angle if 0 <= angle <= 180 else "I don't see the sun!" | ||

| I want to be the best of the best PROGRAMMERS!!! SHOW ME MORE SOLUTIONS!!1!!!11! | ||
| </div> | ||
| <div class="answer"> | ||
| Okay, okay! That's the spirit!=) | ||
| The formula is the same as in our decision, but instead of dividing the line into components of the list, it is simply used | ||
| slicing. | ||
| <pre class="brush: python"> | ||
| def sun_angle(time): | ||
| t = int(time[:2]) * 15 + int(time[3:]) / 4 - 90 | ||
| return t if 0 <= t <= 180 else "I don't see the sun!" | ||

| I want more! | ||
| </div> | ||
| <div class="answer"> | ||
| Look at this solution. With the help of the datetime module, we can perform our calculation in time units, | ||
| and only then translate the value into angle units. | ||
| <pre class="brush: python"> | ||
| import datetime | ||
| def sun_angle(time): | ||
| start=datetime.datetime.strptime("06:00","%H:%M") | ||
| end=datetime.datetime.strptime("18:00","%H:%M") | ||
| time=datetime.datetime.strptime(time,"%H:%M") | ||
| diff=(time-start).seconds/60*0.25 | ||
| return diff if start<=time<=end else "I don't see the sun!" | ||

| Потрібна допомога! | ||

| <div class="answer"> | ||
| Давай розпочнемо з підготовки нашого вхідного рядка перед розрахунком. Ми передамо до змінних "h" та "m" значення | ||
| годин і хвилин відповідно, вже конвертовані у цілочисельний тип даних за допомогою функцій map() та int(). | ||
| Форма запису через кому "h, m = map(int, ...)" еквівалентна до наступної форми "h = int(...)" та "m = int(...)". | ||
| Ми використовуємо функцію int() до кожного елементу списку розділеного рядка використовуючи сепаратор ":". | ||

| Я вже не знаю що робити. Мені потрібна маленька підказка. | ||
| </div> | ||
| <div class="answer"> | ||
| Перейдемо до формули розрахунку. Години і хвилини співвідносяться до градусів наступним чином: 6 годин = 90 градусів, | ||
| отже 90/6 = 15, 1 година - це 15 градусів; 6 годин = 360 хвилин = 90 градусів, отже 90/360 = 0.25, 1 хвилина - це 0.25 градуса. | ||
| Враховуючи, що 6:00 це має бути 0 градусів, то при розрахунку нам потрібно це врахувати віднявши 90 від результату. | ||
| Формула буде наступною. | ||
| <pre class="brush: python"> | ||
| time = "07:00" | ||
| h, m = map(int, time.split(':')) | ||

можна написати один раз from datetime import datetime і тоді далі не треба буде двічі писати datetime.datetime...буде трохи чистіший код
