学习python异常处理，rasie ShortInputException(len(s),3)，invalid syntax错误

3.0版本提示这一句invalid syntax错误，该怎么写
class ShortInputException(Exception):
'''A user-defined exception class.'''
def __init__(self,length,atleast):
Exception.__init__(self)
self.length=length
self.atleast=atleast
try:
s=input('Enter something--->')
if len(s)<3:
rasie ShortInputException(len(s),3)
#O the work cam continue as usual here
except EOFError:
print('\nWhy did you do an EOF on me?')
except ShortInputException as x:
print('ShortInputException:The input was of length%d,\
was expecting at least %d'%(x.length,x.atleast))
else:
print('No exception was raised.')

class ShortInputException(Exception):
'''A user-defined exception class.'''
def __init__(self, length, atleast):
Exception.__init__(self)
self.length = length
self.atleast = atleast
try:
s = input('Enter something--->')
if len(s) < 3:
raise ShortInputException(len(s), 3)
#O the work cam continue as usual here
except EOFError:
print('\nWhy did you do an EOF on me?')
except ShortInputException as x:
print('ShortInputException:The input was of length%d,\
was expecting at least %d' % (x.length, x.atleast))
else:
print('No exception was raised.')

注意最后一个else的缩进
