Не очень хорошо, что main() определяется до определения подфункций, вызываемых main(). Лучше соблюдать логику кода: сначала определение подфункций, а уже потом больших функций.

Если хочется сделать сплит по пробельным символам, то советую такую конструкцию. В случае введения двойного пробела ваш вариант вставит " " в список, а предложенная - нет. 😌

expression_array = expression.split(' ')
array_of_operands = []

Очень уместное и лаконичное использование конструкции try-except для определения типов👍

nums.append(left_int)

Логичнее было бы назвать переменную списком чисел, т.к. операнд - это +, -, /, *, и т.п.

Куда потерялся пробел?😢

Снова пробел...


answer = None

if expression_array[1] == '+':

Уместнее было бы записать операнд в переменную и сравнивать её значение, но это так, перфекционизм

По PEP8 тут нужны пробелы)) Сейчас на оценку не влияет, но в будущем обращайте внимание)

Такие комментарии лучше удалять из кода, если они не несут дополнительной информации 😌

Хороший вариант сказать пользователю о делении на ноль!)

README малоинформативный. Не указан вклад каждого из членов команды, нет примеров использования программы: что она получает на вход и что выдает на выходе.
Здорово, что дана команда для вызова из терминала!

Хорошая работа!
Основное задание - работа с гитом в команде - выполнено отлично; небольшие комментарии по стилю и логике кода, PEP8, отступам и неймингу переменных - это советы на будущее (в следующих дз на это будем обращать внимание).

Так что молодцы!

Итог:
Функции: 1.6 * 5 = 8
Ветки и пулл-реквесты: 1 балл
README: 0.5
Доп. балл за фото: 1

Итог: 10.5
