try:

target_file="/root/Django-1.7.11"
four=file('mylog.txt','w')
child.logfile=four 输入输出写道文件里面
child.expect('(?i)password') （？i）表示不区别大小写
child.sendline(password)
child.expect('#')
child.sendline('tar -czf /mnt/mimi.tar.gz '+target_file)
child.expect('#')
print child.before
child.sendline('exit')
four.close()
except:
print "failed"
child1=pexpect.spawn('/usr/bin/scp',[user+'@'+ip+':/mnt/mimi.tar.gz','/mnt/'])
four1=file('loffile.txt','w')
child1.logfile=four1
child1.expect('(?i)password')
child1.sendline(password)
child1.expect(pexpect.EOF) 匹配缓冲区EOF（结尾），保证文件复制正常完成
