Python PEXPECT中的循环行

我创建了一个名为“commands.txt”的txt文件，它包含两个命令（2行）

我想在交换机中运行这两个命令，但只执行一个命令。下面是我的脚本的样子：

 def shvlan(device,child):  
   commandFile = open('commands.txt', 'r') 
   commands = [i for i in commandFile]  
   for command in commands:  
    child.sendline(command)  
    child.expect('.*#')  
    vlans = child.after  
    child.close()  
    print device + ' conn closed'  
    print 'sh run vlan executed'  
    print vlans  
    return vlans

有什么建议说明为什么只使用.txt文件的第1行吗？

您正在关闭循环中的连接。你必须在循环之后移动那部分代码。试试这样的

 def shvlan(device,child):
     vlans = []
     with open('commands.txt', 'r') as commands: 
         for command in commands:  
             child.sendline(command)  
             child.expect('.*#')  
             vlans.extend(child.after.splitlines())  

     child.close()  
     print device + ' conn closed'  
     print 'sh run vlan executed' 
     print vlans  
     return vlans

胃口大开！！！！！正在执行多个命令…非常感谢。我们可以在列表中用逗号（，）分隔每一行吗？现在，它在列表中以两个元素的形式出现：uuuuuuuuu切换1#sh run vlan 158 uuuuuuuuo！命令：显示正在运行的配置vlan 158！时间：2018年7月19日星期四05:46:37(版本7.1)N1(1c)(虚拟局域网配置158)(虚拟局域网配置158)(名称营销)(模式制造路径)(交换机1)sh运行虚拟局域网159)！命令：显示正在运行的配置vlan 159！时间：2018年7月19日星期四05:46:42 \uuuuu版本7.1（4）N1（1c）\uuuuuuuu vlan配置159 \uuuuuuuuuuu vlan 159 \uuuuuuuu名称销售\uuuuuuu模式FabricPath每行以“\uuuuuuuuuuuu”开头是一个新行。我添加了“uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu？

 def shvlan(device,child):
     vlans = []
     with open('commands.txt', 'r') as commands: 
         for command in commands:  
             child.sendline(command)  
             child.expect('.*#')  
             vlans.extend(child.after.splitlines())  

     child.close()  
     print device + ' conn closed'  
     print 'sh run vlan executed' 
     print vlans  
     return vlans
