Я делаю калькулятор, проблема в строке 42 TypeError: неподдерживаемые типы операндов для ** или pow(): 'str' и 'int'

не могу понять строку 42, продолжаю получать ошибку TypeError: неподдерживаемые типы операндов для ** или pow(): 'str' и 'int' может кто-нибудь посоветовать мне, как это исправить, поскольку я застрял на нем в течение нескольких часов как работает код, вы запускаете его, а затем выбираете, какой тип расчета вы хотите сделать, в этом случае область круга сломана, и по какой-то причине он не будет работать, как он должен работать, так это то, что проверка проверки проверяет, является ли строка цифры или буквы, и если это цифры, он продолжится, а если это буквы, он перезапустится и скажет, что вам нужно выбирать цифры, а не буквы
