Python Glade пример. Калькулятор # 21

В данном примере вы увидите, как сделать калькулятор используя Glade и ваш редактор. Можно запрограммировать так, чтобы он вычислял математические функции, возводил в степень, извлекал корни любой степени...

Для начала создаём проект Glade, заполняем его элементами (кнопки, поля).

Теперь переходим к исходному коду вашего проекта:

Будет использоваться огромное количество функций и команд, так как программировать придётся каждую кнопку.

Не буду перечислять подробно каждое действие, так как всё проекты начинаются одинаково.

Все тонкости уже были описаны в предыдущем посте.

Вот исходный код Python-файла:
