Python之反射练习
# 什么是反射？可以用字符串的方式去访问对象的属性 class Test(): _name = "sss" def fun(self): return "Helloword" t = Test() # print(hasattr(t,"_name")) #hasattr(obj,name)#查看类里面有没有name属性 # print(hasattr(t,"fun")) #True if hasattr(t,"_name"): print(getattr(t,"_name")) #sss if hasattr(t,"fun"): print(getattr(t,"fun")()) #Helloword if not hasattr(t,"age"): #如果属性不存在 print("没有该属性和方法，我来给设置一个") setattr(t,"age","18") #给t对象设置一个默认值，默认age=18 print(getattr(t,"age"))
