运行一小段代码出错，网上搜索无果，请教各位：



import pexpect

child = pexpect.spawn('telnet 61.XXX.52.210')

child.expect('Username:')

child.sendline('zte')

……

运行到child.expect('Username:')时，IDLE出错，错误信息如下：



Traceback (most recent call last):

  File "<pyshell#9>", line 1, in <module>

    child.expect('Username:')

  File "/usr/lib/python2.6/site-packages/pexpect.py", line 1311, in expect

    return self.expect_list(compiled_pattern_list, timeout, searchwindowsize)

    return self.expect_loop(searcher_re(pattern_list), timeout, searchwindowsize)
