函数内的 python locals() 包括在函数外导入的类

问题描述

考虑以下代码：

# import a class from another module within package
from .continuous import Continuous
from typing include List,Dict

def build_two_compartment_models(model_descriptions: Dict) -> List:
    print(model_descriptions)

我在 build_two_compartment_models 中设置了一个断点，并惊讶地看到当我运行 Continuous 时列出了 locals() 类。我认为 locals() 只会包含 model_descriptions（可能还有 Dict 和 List）。相反，它包括：

为什么会在这里？尤其是 Continuous ，它是在函数外显式导入的。我对局部变量有什么不了解？
