使用inspect返回包内定义的类列表

Question

我有以下模块结构：

Person.py内的代码是：

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

在Test.py内，我想知道Person.py和Vechile.py中定义的类名。

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)

我得到的答案只有这个：

<Fetch.Vechile.vechile object at 0x0000000000DD0C18>

我哪里错了？如何获取Person和Vechile中定义的类列表？

Answer 1

您当前正在将模块名称作为字符串传递给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，为其提供模块。

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

我想我修正了你的错误。

Person.py

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

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

Vechile.py

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

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

Test.py（保持不变）

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.display_type("Auto")
print (v)

main.py中有两个错误。这是一个固定版本，其中包含更改：

import inspect
from Fetch import Vechile
from Fetch import Person

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

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