这篇文章主要介绍了python__双划线参数代码实例解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
代码如下
'''
>>> Class1.__doc__ # 类型帮助信息 'Class1 Doc.'
>>> Class1.__name__ # 类型名称 'Class1'
>>> Class1.__module__ # 类型所在模块 '__main__'
>>> Class1.__bases__ # 类型所继承的基类 (<type 'object'>,)
>>> Class1.__dict__ # 类型字典，存储所有类型成员信息。 <dictproxy object at 0x00D3AD70>
>>> Class1().__class__ # 类型 <class '__main__.Class1'>
>>> Class1().__module__ # 实例类型所在模块 '__main__'
>>> Class1().__dict__ # 对象字典，存储所有实例成员信息。 {'i': 1234}
'''
class Ren(object):
'''ok,it's crazy'''
name = 'a human being'
@staticmethod
def look():
return "ok"
class Men(Ren):
sex = "male"
class Women(Ren):
sex = "female"
class Baby(Women):
sex = "children"
if __name__ == "__main__":
r = Men()
print(Ren.__dict__, "__dict__")
print(Ren.__doc__, "__doc__")
print(Men.__doc__, "__doc__")
print(Ren.__bases__, "__bases__")
print(Baby.__bases__[0].__bases__, "__bases__")
print(Baby.__bases__[0].__dict__, "__dict__")
print(Baby.__dict__, "__dict__")
print(Men.__bases__[0](), "__bases__")
print(Men.__name__, "__name__")
print(r.__class__(), "__class__")
print(r.__module__, "__class__")
print(Men.__module__, "__class__")
print(__file__)
结果
