python和c++,java等面向对象语言一样都提供了异常处理机制。

 

 

 

#coding:utf-8 

def fun(a, b):
    if b == 0:
        raise Exception('info', 'zero')  
    else:
        return a / b  
i = 2
while i > 0:
    try:
        k = 0
        n = 5 / k
    except  KeyboardInterrupt:#键盘异常：ctr+ d可以推出循环
        break               
    except Exception, e:      #异常对象
        print 'error', e      #输出异常信息
    finally:
        'finally'
    i -= 1
print 'end'

print fun(1, 1)
print fun(1, 0)
