使用键入和分配错误值时不显示警告/通知/错误

Question

I'm new to python and i know that types can't be enforced and the maximum we can do is provide "warnings" . So i'm using typing with python3.7 with pycharm professional. But i don't get any warning, notification or indication that i'm using the wrong types. Example:

from typing import List

class MyClass:

__event_ids: List[str]

def __init__(self):

    self.__event_ids = 15 <---- This don't react in any way

    return

I've researched it, but no tutorial stated any additional steps i need to take to make it work properly

Answer 1

试试mypy ，一个独立的类型检查器。
