如何告诉 python 如何告诉 python 将意外变量类型传递到函数的意外变量类型在上下文中正确
原标题:How to tell python that the unexpected variable type passing to a function is correct in the context
I m new to Python 3 and testing with pytest. Sometimes, I want to test that my function raises TypeError or AssertionError when I provide it with type that it is not supposed to process. Consider this simple example: import pytest def concatenate_string(first_string: str, second_string: str) -> str: return first_string + second_string def test_concatenate_string_raises_type_error(): with pytest.raises(TypeError) as pytest_wrapped_e: concatenate_string( abc , 1) assert e.type == TypeError My problem here is, that when I provide the integer 1 to the function concatenate_string, PyCharm warns me about unexpected type assigned. I know this is a correct behaviour, but is there a way to tell the program (e.g. by some other annotation): "I know what I m doing, I really want to have this type here, don t warn be about it."? I know I can just tell the editor to ignore it, but it feels somehow wrong to me.

From here: concatenate_string( abc , 1) # type: ignore this should suppress the type checking for that line
