Question

我有以下模塊結構的包內定義的類的列表：

內部Person.py的代碼是：

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

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

內部Vechile.py是：

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

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

裏面__init__.py：

pass 

而且裏面Test.py我想知道里面Person.py和Vechile.py定義的類名。

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) 

，我得到的答案是隻有這個：

<Fetch.Vechile.vechile object at 0x0000000000DD0C18>

我要去哪裏錯了？我如何獲得Person和Vechile中定義的類別列表？

Answer 1

您正在傳遞一個模塊名作爲一個字符串inspect.getmembers這裏：

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

這將是尋找一個字符串實例的成員，一個模塊的不是成員。要找到某個模塊的成員，請給指定一個模塊。

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

我想我解決了你的錯誤。

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（保持不變）

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)

有兩件事情錯在main.py。這裏有一個固定的版本，其中包含以下變化：

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)
