反射(hasattr , getattr, setattr) 输入的字符串用来运行程序

import easygui

	print(‘%s is talking‘%self.name)

class Dog(object):
	def __init__(self,name):
		self.name = name 
	
	def eat(self, food):
		print(‘%s is eating %s‘%(self.name, food))
	

find_info = easygui.enterbox(‘please give me you want‘)
d = Dog(‘ronghua‘)

if hasattr(d, find_info): #判断这个变量是否在函数内
	func = getattr(d, find_info)  #找到这个变量 
#	print(getattr(d, find_info)) 
	func(‘包子‘)  #运行
else:
	setattr(d, find_info, bulk)  # 如果bulk 函数不在类内，载入bulk函数，用find_info 命名

func = getattr(d, find_info)
func(d)
