Python编程从入门到实践 10-9 沉默的猫和狗

修改你在练习10-8中编写的except 代码块，让程序在文件不存在时一言不发。

#!/usr/bin/env python
# -*- coding: utf-8 -*-
filenames=['cats.txt','dogs.txt']
for filename in filenames:
	try:
		with open(filename) as file_object:
			contents=file_object.read()
			print("Their names are "+contents+" .")
	except IOError:
		pass
	
		

结果
