python - 使用检查返回包内定义的类列表

Question

我有以下模块结构:

里面的代码Person.py是:

class person:
    def __init__(self,name,age):
        self.name = name
        self.age = age

    def displayage(self):
        print ("Your age is {0}".format(self.age))

内部Vechile.py是:

class vechile:
    def __init__(self,type):
        self.type = type

    def display_type(self):
        print ("Your vechile type is {}".format(self.type))

内部__init__.py :

pass

里面Test.py我想知道Person.py里面定义的类名和Vechile.py .

import inspect
from Fetch import Vechile
from Fetch import Person

modules = ['Vechile','Person']
for module in modules:
    for name, obj in inspect.getmembers(module):
        if inspect.isclass(name):
            print (obj)

v = Vechile.vechile("Auto")
print (v)

我得到的答案只是这样:

<Fetch.Vechile.vechile object at 0x0000000000DD0C18>

我哪里出错了？如何获取 Person 中定义的类列表和Vechile ？

Answer 1

您当前正在将模块名称作为字符串传递到此处的 inspect.getmembers:

modules = ['Vechile','Person']
for module in modules:
    for name, obj in inspect.getmembers(module):
        ...

这将查看字符串实例的成员，而不是模块的成员。要查找模块的成员，请为其提供一个模块。

modules = [Vechile, Person]
for module in modules:
    for name, obj in inspect.getmembers(module, inspect.isclass):
        # no need to check if is class here
        ...
