python学习：反射

–

#反射学习
class Teacher(object):
    dic = {"查看学生":"show_student", "查看老师":"show_teacher"}

    @classmethod
    def show_student(self):
        print("show_student")

    def show_teacher(self):
        print("show_teacher")



#反射
if hasattr(Teacher, 'dic'):
    ret = getattr(Teacher, 'dic')
    print(ret)

#获取属性
ret2 = getattr(Teacher,'show_student')
ret2()

#获取方法调用结果
alex = Teacher()
func = getattr(alex,'show_teacher')
func()

#根据字符串执行对应的方法名
# for k in Teacher.dic:
#     print(k)
alex = Teacher()
#key = "查看学生"
key = "查看老师"
func = getattr(alex, Teacher.dic[key])
func()
