1.针对类中方法的反射
# 反射的使用
class Dog(object): def __init__(self,name):
self.name = name def eat(self):
print('%s is eating...'%self.name)
def bulk(self):
print('%s is yaling...'%self.name) d = Dog('wt')
choice = input('>>:').strip() if hasattr(d,choice):
func = getattr(d,choice)
func()
else:
setattr(d,choice,bulk)
func = getattr(d, choice)
func(d)
2.针对类成员变量的使用
# 反射的使用
class Dog(object): def __init__(self,name):
self.name = name def eat(self):
print('%s is eating...'%self.name)
def bulk(self):
print('%s is yaling...'%self.name) d = Dog('wt')
choice = input('>>:').strip() if hasattr(d,choice):
print(getattr(d,choice))
else:
setattr(d,choice,'hjc')
print(getattr(d,choice))
总的来说就是判断是否有输入的choice,若有则进行输出,若没有则进行赋值或者替换。
