您可以使用字符串实例化类吗？

不确定这是否是您想要的，但是似乎更Python化的方式来实例化字符串中列出的一堆类：

class idClasses:    class ID12345:pass    class ID01234:pass# could also be: import idClassesclass ProcessDirector:    def __init__(self):        self.allClasses = []    def construct(self, builderName):        targetClass = getattr(idClasses, builderName)        instance = targetClass()        self.allClasses.append(instance)IDS = ["ID12345", "ID01234"]director = ProcessDirector()for id in IDS:    director.construct(id)print director.allClasses# [<__main__.ID12345 instance at 0x7d850>, <__main__.ID01234 instance at 0x7d918>]
