反射

--------------每一点滴的进展都是缓慢而艰巨的，一个人一次只能着手解决一项有限的目标。

# ---------------------------------------------------------------------------------#

# 本节主要内容:

#         return a+b

# 1. 看代码写结果并画图表示对象和类的关系积极执行过程

# class StarkConfig(object):
#     list_display = []
#
#     def get_list_display(self):
#         self.list_display.insert(0, 33)
#         return self.list_display
#
#
# class RoleConfig(StarkConfig):
#     list_display = [11, 22]
#
#
# s1 = StarkConfig()
# s2 = StarkConfig()
#
# result1 = s1.get_list_display()
# print(result1)
#                 # -- >   33
# result2 = s2.get_list_display()
# print(result2)
# -- >   33

# 2. 看代码写结果并画图表示对象和类的关系积极执行过程


# class StarkConfig(object):
#     list_display = []
#
#     def get_list_display(self):
#         self.list_display.insert(0, 33)
#         return self.list_display

# 4. 看代码写结果

# class Base(object):
#     pass
#
# class Foo(Base):
#
#     pass
#
# print("issubclass(Base,Foo)")  # -- > False


# ---------------------------------------------------------------------------------#
# 5. 看代码写结果
# 如果有以下 handler. py文件,请在run,py中补充代码实现
# 获取 handler中所有成员名称:dir( handler)

  #-->['Base', 'F1', 'F2', 'F3', 'F4', 'F5', 'F6', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__']

# 获取 handle中名字叫Base的成员


# 检查其他成员是否是Base类的子类(不包含Base),如果是则创建对象并添加到objs列表中

#  handler.py
# class Base(object):
#     pass
#
# class F1(Base):
#     pass
#
# class F2(Base):
#     pass
#
# class F3(F2):
#     pass
#
# class F4(Base):
#     pass
#
# class F5(object):
#     pass
#
# class F6(F5):
#     pass
#
# #  run.py
# import handler
#
#
# def func():
#     objs = []
#
#     name_list = dir(handler)
#     print(name_list)
#
#
# if__name__ == '__main__':
#
#     func()j
# ---------------------------------------------------------------------------------#
#6. 补充代码
class Foo(object):
    def __init__(self,name=None,age=None):
        self.name = "小猪佩奇"
        self.age = 100
obj = Foo
setattr(obj,"email","xiaozhupeiqi@zhuzhu.com")


#请实现 : 一行代码实现获取obj中所有成员(字典类型)


# ---------------------------------------------------------------------------------#
#7.看代码写结果

class Foo(object):
    def __init__(self,name=None,age=None):
        self.name = "小猪佩奇"
        self.age = 100
obj = Foo
setattr(obj,"email","xiaozhupeiqi@zhuzhu.com")

v1 = getattr(obj,"email")
v2 = getattr(Foo,"email")

print(v1,v2)
