为什么 PyCharm 不显示类型提示验证错误

Question

I'm using PyCharm 2021.2.2 (Community Edition). I'm learning about Python Type Hints from the FastAPI docs . When I write a function like this

def get_name_with_age(name: str, age: int) -> str:
    name_with_age = name + " is this old: " + age
    return 10

Shouldn't Pycharm warn me that I'm attempting to return an int but the function is supposed to return a string? And / or shouldn't it warn me that I can't concatenate a string with an int? Pycharm doesn't warn me about either of these things..

Answer 1

Apparently I was in "power save" mode. Once disabled this, type hint validation started working.
