Есть три ситуации

Есть три ситуации, в которых только что созданную переменную нельзя аннотировать типом: распаковка кортежей, циклы for и инструкции with.

Все эти примеры некорректны:


name: str, age: int = student

for x: int in numbers: 
    ...

with connection() as conn: Connection:
    ...

Правильный способ указать тип таких переменных — объявить их заранее, без инициализации:


conn: Connection
with connection() as conn:
    ...
