python知识点积累_2

异常之间是并列的，也就是说只能在一次错误中从上到下，抛出一次异常，抛出后跳出异常语句。

import time
try:
    print "ai"
    time.sleep(1)
    res = True
    l = [1,2]
    print l[5]
#except Exception as e:
#    print e,"11"
except SyntaxError,e:
    print e
except IndexError, e:
    print Exception
    print e,"1"
except Exception as e:
    print e

>>> 
ai
<type 'exceptions.Exception'>
list index out of range 1
