<p>На курсе &#171;Программирование на Питоне&#187; мы во многом продолжим изучать то, о чем узнали на вводном курсе, но на гораздо более детальном уровне. И начнем мы этот путь с того, что еще раз взглянем на переменные в Питоне.</p>



<p class="has-background" style="background-color:#ffe8c4">Перед прохождением этого занятия рекомендую изучить первый раздел вводного курса или, как минимум, познакомиться с <a href="https://www.dmitrymakarov.ru/intro/software-03/">программой Google Colab</a>, которую мы используем в нашей работе, а также повторить <a href="https://www.dmitrymakarov.ru/intro/coding-basics-04/">основы программирования</a>.</p>

<h3 class="wp-block-heading" id="0-kak-obyavit-peremennuyu-v-pitone">Как объявить переменную в Питоне</h3>



<p>Создание или объявление переменной в Питоне происходит в тот момент, когда вы присваиваете ей определенное значение. Это очень удобно. Заранее объявлять переменную не требуется.</p>

<p class="has-background" style="background-color:#ffe8c4">Возможно, вы спрашиваете себя зачем инженеру машинного обучения в таких деталях разбираться в типах переменных. Одним из наиболее очевидных применений является предварительная обработка данных, поступивших, скажем, в формате строки (str), хотя с точки зрения логики это должно быть целое число (int).</p>



<h3 class="wp-block-heading" id="4-imenovanie-peremennykh">Именование переменных</h3>



<p>Напомню, что имя переменной может включать только латинские буквы и цифры, а также символ подчеркивания. Одновременно оно не должно начинаться с цифры. Питон отличает заглавную от строчной буквы. Пробелы и кириллицу использовать нельзя.</p>



<p>Как я не устаю повторять, название переменных должно быть осознанным. Это упростит работу с длинным кодом.</p>



<p>Посмотрим на допустимые названия переменных:</p>
