为什么pycharm在类或函数之外为None给出“预期类型”警告？

Question

为什么pycharm在此代码的类或函数之外为None发出“预期类型”警告：

def blah():
    hiya = None  # type: dict   # No type warning

class Foo:
    bar = None  # type: dict    # No type warning

asf = None  # type: dict        # Expected type 'dict', got 'None' instead

Answer 1

我正在使用Pycharm，对我来说这很好

def blah():
hiya = None  # type: #dict   # No type warning

class Foo:
    bar = None  # type: #dict    # No type warning

asf = None  # type: #dict        # Expected type 'dict', got 'None' instead

也许是您设置中的内容。
