try块后面必须至少有一个except或finally。你在这里没有发现任何异常，所以只需摆脱try部分：

#!/usr/bin/python
import pxssh
import getpass

s = pxssh.pxssh()
hostname = raw_input('hostname:')
username = raw_input ('username:')
password = getpass.getpass ('password:')
s.login (hostname,username,pawssword)
s.sendline('uptime')
s.prompt()
print s.before
s.sendline('ls-l')
s.prompt()
print s.before
s.sendline('df')
s.prompt()
print s.before
