Python 3.x python 3中ImportLib的属性错误

我正在尝试动态导入特定的模块和方法。为了动态导入模块，我编写了CheckCode.py，它有一个类SystemConfigure和方法Snp_Configure。需要导入的模块是SnpBase.py，它依次具有类SnpBase和方法Unix\u Base\u Configure。为了动态导入模块和方法，我使用importlib功能。然而，当我做同样的事情时，我得到了AttributeError。有人能帮我找出缺了什么吗。谢谢

检查代码.py

class SystemConfigure():

    def __init__(self,snp_dict):
        print ("I am in Init of the SystemConfigure")
        SystemConfigure.Snp_Configure(self,snp_dict)

    def Snp_Configure(self,snp_dict):
        dict = snp_dict
        osname = dict['osname']
        protocol = dict['protocol']
        module = "Snp" + protocol
        func_string = module + "." +osname + "_" + protocol + "_" + "Configure"
        #func_string = osname + "_" + protocol + "_" + "Configure"
        print ("You have called the Class:", module, "and the function:", func_string)
       # my_method =getattr(import_module(module),"SnpBase.Unix_Base_Configure")
        mod = import_module(module)
        #return mod.SnpBase.Unix_Base_Configure(snp_dict)
        func = getattr(mod, func_string)
        func(snp_dict)

class SnpBase():

    def __init__(self,dict):
        pass
        print("BASE INIT")

    def Unix_Base_Configure(self,dict):
        print ("GOT IN THE UNIX BASE CLASS FUNCTION")

    def Linux_Base_Configure(self,dict):
        print("GOT IN THE LINUX BASE CLASS FUNCTION")

SnpBase.py

class SystemConfigure():

    def __init__(self,snp_dict):
        print ("I am in Init of the SystemConfigure")
        SystemConfigure.Snp_Configure(self,snp_dict)

    def Snp_Configure(self,snp_dict):
        dict = snp_dict
        osname = dict['osname']
        protocol = dict['protocol']
        module = "Snp" + protocol
        func_string = module + "." +osname + "_" + protocol + "_" + "Configure"
        #func_string = osname + "_" + protocol + "_" + "Configure"
        print ("You have called the Class:", module, "and the function:", func_string)
       # my_method =getattr(import_module(module),"SnpBase.Unix_Base_Configure")
        mod = import_module(module)
        #return mod.SnpBase.Unix_Base_Configure(snp_dict)
        func = getattr(mod, func_string)
        func(snp_dict)

class SnpBase():

    def __init__(self,dict):
        pass
        print("BASE INIT")

    def Unix_Base_Configure(self,dict):
        print ("GOT IN THE UNIX BASE CLASS FUNCTION")

    def Linux_Base_Configure(self,dict):
        print("GOT IN THE LINUX BASE CLASS FUNCTION")

错误消息

  func = getattr(mod, func_string)
AttributeError: module 'SnpBase' has no attribute 'SnpBase.Unix_Base_Configure'

模块

SnpBase

没有名为

Unix\u Base\u Configure

的函数

---

模块

SnpBase

有一个名为

SnpBase

的类，该类有一个名为

Unix\u Base\u Configure的函数

因此，错误是：

AttributeError: module 'SnpBase' has no attribute 'SnpBase.Unix_Base_Configure'

是正确的。
我使用importlib import\u模块中的以下语句，我还使用以下命令调用CheckCode。m=SystemConfigure（{'protocol'：'Base'，'osname'：'Unix'，'device'：'dut'}）
