<p>На сегодняшнем занятии мы подробнее поговорим про три типа данных в Питоне: списки, кортежи и множества. Каждый из них относится к так называемым коллекциям (collections), то есть типам данных, содержащим сразу несколько элементов.</p>



<p>При этом у каждого из них есть свои важные особенности.</p>

<h3 class="wp-block-heading" id="9-list-comprehension">List comprehension</h3>



<p>А теперь рассмотрим list comprehension. По сути, list comprehension позволяет превратить один список в другой, <em>преобразовывая</em> и <em>отбирая</em> элементы исходного списка.</p>

<p>На основе этих двух примеров давайте разберемся с синтаксисом list comprehension.</p>

<ul class="wp-block-list">
<li>Вначале идет выражение, преобразующее каждый элемент исходного списка.
<ul class="wp-block-list">
<li>Если просто указать переменную, как это было в первом примере с переменной

<li>Во втором примере, мы изменили регистр с заглавной буквы на строчную с помощью <strong>метода .lower()</strong>.</li>
</ul>
</li>



<li>Затем идет блок, по сути, повторяющий цикл <strong>for</strong>.</li>



<li>И наконец, если это необходимо, условие c if, с помощью которого мы можем отобрать не все, а лишь некоторые из элементов исходного списка.</li>
</ul>



<p>Приведу еще один пример.</p>

<h2 class="wp-block-heading" id="22-podvedem-itog">Подведем итог</h2>



<p>Мы подробно рассмотрели три относящихся к коллекциям типов данных, а именно списки, кортежи и множества.</p>



<p>Списки изменяемы и упорядочены. Кортежи упорядочены, но не изменяемы. Множества не упорядочены и не изменяемы. Кроме того, множества всегда содержат только уникальные элементы, повторы не допускаются.</p>
